Definitions
- the present invention relates to an improvement in a method for producing an organic compound using a fluid treatment apparatus which adopts a treatment space defined by at least two treatment surfaces, at least one of which rotates with respect to the other. It also relates to a method for producing an organic compound using a continuous stirrer. More specifically, the present invention relates to the fields of chemistry, biochemistry, agriculture, food, medicine, cosmetics and the like, and more particularly to a chemical reaction using an organic compound and a method for producing an organic compound using a continuous reaction apparatus which is effective and useful for chemical synthesis.
- a reaction process for chemically reacting two or more kinds of substances or one kind of substances themselves to obtain a new substance is roughly classified into a batch type and a continuous type.
- a solvent, a substrate, a reaction agent and the like are put in a container typified by a flask in a laboratory, and the reaction is performed by stirring with a stirrer or the like.
- Both the batch type and the continuous type have been industrially put into practical use, but the reaction field naturally has a volume. The volume in this reaction vessel affects the heterogeneity of reaction conditions in the reaction field.
- a reactant when added to a uniform substrate solution to perform a chemical reaction, it takes a certain amount of time until the concentration of the reactant becomes uniform.
- the reaction agent is added to the solvent and the substrate in the container, the reaction conditions are already different at the start and the end of the addition of the reaction agent. The heterogeneity of the reaction conditions in the reaction field caused by the factors as described above eventually affects the reaction products.
- the desired reaction cannot be ideally performed because various reaction conditions occur in one container. For example, it is not possible to completely select the main reaction and the side reaction, generation of a by-product accompanying it, and in the case of a polymerization reaction, it is difficult to obtain a uniform molecular weight distribution of the obtained product. Including the adhesion of the product to the wall surface of the container, the yield of the reaction product to the product is naturally low.
- the reaction vessel is usually equipped with a stirring device such as a stirrer or a turbine. By increasing the mixing speed of the mixed reaction fluid in the vessel with the stirring device, the uniformity of the reaction field is ensured and the reaction speed is dealt with.
- microreactors, micromixers and microreactors that are microchannel reactors have been proposed as shown in Patent Document 1 and Patent Document 2, and it is possible to synthesize in a minute amount.
- advantages such as high efficiency of temperature control, high efficiency of interfacial reaction, and efficient mixing have been proposed.
- the pressure loss is actually inversely proportional to the fourth power of the flow path as the diameter of the microflow path becomes narrower.
- a pump for sending a fluid is required to have a large sending pressure that is difficult to obtain, and in the case of a reaction involving precipitation, a phenomenon in which a product is clogged in a flow path or a micro flow path is closed by bubbles generated by the reaction, Furthermore, since basically the reaction is expected to the diffusion rate of the molecule, it cannot be said that the micro flow channel is effective and adaptable to all reactions. However, there are many problems such as the need to select the one that is successful. Therefore, the problem of deposits generated in the microreactor as in Patent Document 1 may be avoided by ultrasonic treatment, but irregular turbulence and cavitation in the flow path caused by ultrasonic waves are It is likely that it will not always work well for the reaction.
- Patent Document 3 discloses a thin-film fluid that is disposed so as to be able to approach and separate from each other so as to face each other, and is formed between processing surfaces in which at least one rotates with respect to the other.
- the first issue is to secure the reaction time. Since the fluids are merged in the thin film fluid between the processing surfaces, the diffusion efficiency is unprecedented and as a result, perfect mixing can be realized, but especially in the case of organic reaction, the absolute reaction time is extended. There were times when I wanted to. In order to shorten the reaction time, trial and error such as extremely raising the reaction temperature or increasing the amount of catalyst is repeated, but adverse effects such as increase of by-products and danger are conspicuous. Also, if the processing surface is made extremely large, it is possible to secure the reaction time, but such problems as large cost and installation area are not realistic.
- Patent Document 4 relating to the applicant of the present application is to dispose each fluid in a thin-film fluid formed between processing surfaces that are arranged so as to be able to approach and separate from each other so that at least one rotates with respect to the other.
- a vessel for depositing fine particles in the thin film fluid to collect the discharge liquid discharged from between the processing surfaces and connecting a tubular container to the lower end of the vessel to be included in the discharge liquid in the tubular container.
- the present proposal is useful for growing crystal nuclei and crystallites, but in organic synthesis, for example, a considerably large tubular container is required to satisfy the retention time of the discharge liquid in the tubular container.
- a separate stirrer or liquid transfer system is often required.
- Patent Document 5 relating to the present applicant discloses a microreactor that employs an annular flow channel defined between processing surfaces that rotate relative to each other, and has a cylindrical stirring space inside the annular flow channel in the radial direction.
- the stirring blade and the screen are arranged in the stirring space, and the stirring energy is applied by the stirring blade to the fluid to be treated immediately before being introduced into the annular flow path, and the stirring blade and the screen are provided between the stirring blade and the screen.
- a fluid treatment arrangement is disclosed that is configured to apply a shearing force.
- Patent Document 5 is intended to realize a homogeneous reaction in the annular flow passage by improving the homogeneity of the fluid to be treated introduced into the annular flow passage. There is no specific description of further processing.
- a mixer for mixing one or more fluids in which a volume body is arranged on the downstream side of a static microreactor.
- the volume body forms a labyrinth wall inside to form a labyrinth-type flow channel.
- the labyrinth-type flow channel is provided to generate turbulence in the passing fluid and promote mixing. It is a thing.
- Patent Document 7 a Taylor reaction device in which a plurality of Taylor vortices are generated in a gap space formed between an outer cylinder and an inner cylinder rotating in the outer cylinder, , A labyrinth passage for suppressing the flow between Taylor vortices is disclosed.
- the reaction device of Patent Document 7 is premised on the generation of Taylor vortices (for example, paragraph 0017 of Patent Document 7), and the structure of the device should be set to conditions under which Taylor vortices can be generated.
- Patent Document 8 if the number of Taylors calculated by the following formula (1) is 2000 or less, Taylor vortices can be stably obtained.
- the labyrinth seal installation interval is set.
- Ta ⁇ R ⁇ b/ ⁇ (b/R) 1/2
- ⁇ the angular velocity of the rotating part (1/sec)
- R the radius of the rotating part (cm)
- b is the outer peripheral surface of the inner cylinder and the inner peripheral surface of the outer cylinder. Is the distance (cm)
- v the kinematic viscosity of the fluid (cm 2 /sec). Since organic solvents often have lower kinematic viscosities than water, there are many restrictions on setting conditions to keep the Taylor number at 2000 or less, and it is not practical to use the apparatus for organic reaction.
- the applicant of the present invention has proposed a method for producing an organic compound using a fluid treatment device or a continuous stirring device, which can sufficiently secure a reaction time and obtain a desired reaction product with high efficiency. It is a proposal.
- the present invention provides a method for producing an organic compound capable of obtaining a target substance with a high yield by sufficiently securing the reaction time even in an organic reaction that requires a relatively long time to complete the reaction.
- the challenge is to provide.
- the target product X is obtained by reacting the raw material A and the raw material B in a chemical reaction process.
- the first fluid treatment is mixing of the raw material A and the raw material B, and it is desired to mix the raw material A and the raw material B more uniformly and faster.
- the reaction between the raw material A and the raw material B is allowed to proceed as the second fluid treatment.
- the reaction conditions for efficiently obtaining the product X are adjusted.
- the reaction conditions include the concentrations of the raw materials A and B, the temperature conditions in the reaction field, the pressure conditions and the stirring conditions, the presence or absence of a catalyst and its optimization, the reaction time, and the like. Therefore, a highly efficient, continuous, inexpensive, and simple processing apparatus must be able to process each of the above processes (first fluid process and second fluid process) with high efficiency.
- the present invention is a method for producing an organic compound, wherein the fluid treatment device used in the production method is an upstream treatment section that treats a fluid to be treated between at least two treatment surfaces that relatively rotate, And a downstream processing unit provided with a plurality of labyrinth seals arranged downstream of the upstream processing unit and having a function of retaining and stirring the fluid to be processed processed by the upstream processing unit.
- the fluid treatment device used in the production method is an upstream treatment section that treats a fluid to be treated between at least two treatment surfaces that relatively rotate, And a downstream processing unit provided with a plurality of labyrinth seals arranged downstream of the upstream processing unit and having a function of retaining and stirring the fluid to be processed processed by the upstream processing unit.

第1処理用部10と第2処理用部20のうち、少なくとも一方の処理用部は、電動機などの回転駆動機構Mにて、他方の処理用部に対して相対的に回転する。回転駆動機構Mの駆動軸は回転軸31に接続されており、この例では、回転軸31に取り付けられた第1処理用部10が第2処理用部20に対して回転する。本実施形態においては、回転軸31は、第1処理用部10の中心にネジなどの固定具32によって固定され、その後端が回転駆動機構Mの駆動軸と接続され、回転駆動機構Mの駆動力を第1処理用部10に伝えて第1処理用部10を回転させるものであり、環状の第2ホルダ22の環状の中央には、回転軸31を軸支するための支持部33を備える。もちろん、第2ホルダ22に支持された第2処理用部20を回転させるようにしてもよく、双方を回転させるようにしてもかまわない。
この実施の形態では、第1処理用部10と第2処理用部20とは、少なくとも何れか一方が、少なくとも何れか他方に、回転軸31の軸方向に対して接近及び離反可能となっており、両処理用面1、2は接近及び離反することができる。
被処理流動体(この例では第1流体と第2流体)は、流体圧付与機構P1、P2によって流体処理装置Fに供給される。流体圧付与機構P1、P2には、種々のポンプを用いることができるものであり、所定の圧力で被処理流動体を流体処理装置Fに供給できる。また圧送時の脈動の発生を抑制するために、流体圧付与機構P1、P2として、加圧容器を備えた圧力付与装置を採用することもできる。被処理流動体が収納された加圧容器に加圧用ガスを導入し、その圧力によって被処理流動体を押し出すことにより、被処理流動体を圧送することができる。
前記の被処理流動体は、流体圧付与機構P1、P2により圧力が付与される。この加圧状態で、第1流体と第2流体とを含む被処理流動体が、第1導入部d1と、第2導入部d2から両処理用面1、2間に導入される。
レイノルズ数Re=慣性力/粘性力=ρVL/μ=VL/ν 式(2)
ここで、ν=μ/ρは動粘度、Vは代表速度、Lは代表長さ、ρは密度、μは粘度を示す。
そして、流体の流れは、臨界レイノルズ数を境界とし、臨界レイノルズ数以下では層流、臨界レイノルズ数以上では乱流となる。
なお、第1処理用部10の回転数を高めてレイノルズ数を上げることで、薄膜流体にせん断力を加えてもよい。
遠心力F=ma=mv2/R 式(3)
ここで、aは加速度、mは質量、vは速度、Rは半径を示す。
次に、第1処理用面1と第2処理用面2とを接近させる方向に作用させる力を処理用部に付与するための接面圧付与機構について説明する。この実施の形態では、接面圧付与機構は、第2ホルダ22に設けられ、第2処理用部20を第1処理用部10に向けて付勢する。前記の接面圧付与機構は、第1処理用部10の第1処理用面1と第2処理用部20の第2処理用面2とに対して、互いに接近する方向に加えられる力(以下、接面圧力という)を発生させるための機構である。この接面圧力と、流体圧付与機構P1、P2による流体圧力などの両処理用面1、2間を離反させる力との均衡によって、1mm以下のnm単位ないしμm単位の微小な膜厚を有する薄膜流体を発生させる。言い換えれば、前記力の均衡によって、両処理用面1、2間の間隔が所定の微小間隔に保たれる。
図2に示すように、第1処理用部10の第1処理用面1には、第1処理用部10の中心側から外側に向けて、即ち径方向について伸びる溝状の凹部13を形成して実施してもよい。この凹部13の平面形状は、図2(B)へ示すように、第1処理用面1上をカーブして或いは渦巻き状に伸びるものや、図示はしないが、真っ直ぐ外方向に伸びるもの、L字状などに屈曲あるいは湾曲するもの、連続したもの、断続するもの、枝分かれするものであってもよい。また、この凹部13は、第2処理用面2に形成するものとしても実施可能であり、第1及び第2の処理用面1、2の双方に形成するものとしても実施可能である。このような凹部13を形成することによりマイクロポンプ効果を得ることができ、被処理流動体を第1及び第2の処理用面1、2間に吸引することができる効果がある。
この凹部13の先端と第1処理用部10の外周面11との間には、凹部13のない平坦面14が設けられている。
前記の第2導入部d2の第2導入口d20を第2処理用面2に設ける場合は、対向する第1処理用面1の平坦面14と対向する位置に設けることが好ましい。
第2導入口d20の形状は、図1に示すように、リング状のディスクである第2処理用面2の中央の開口を取り巻く同心円状の円環形状などの連続した開口であってもよく、図2(B)や図3(B)に示すように、円形などの独立した開口であってもよい。また、第2導入口d20を円環形状とした場合、その円環形状の開口部は全周にわたって連続していてもよいし、一部分が不連続であってもよい。
前記の被処理流動体の種類とその流路の数は、図1の例では、2つとしたが、1つであってもよく、3つ以上であってもよい。図1の例では、第2導入部d2から上流側処理空間3に第2流体を導入したが、この導入部は、第1処理用部10に設けてもよく、双方に設けてもよい。また、一種類の被処理流動体に対して、複数の導入部を用意してもよい。また、各導入口は、その形状や大きさや数は特に制限はなく適宜変更して実施し得る。また、前記第1及び第2の処理用面間1、2の直前或いはさらに上流側に導入口を設けてもよい。また、各流体における第1、第2という表現は、複数存在する流体の第n番目であるという、識別のための意味合いを持つに過ぎないものであり、第3以上の流体も存在する。図6-8、図10に、第3の被処理流動体である第3流体の流路である第3導入部d3とその開口d30を示す。第3導入部d3は、第2導入部d2と同じように、第2処理用部20の内部に設けられた通路であり、その一端が、第2処理用面2にて開口するものであって、その導入開口(第3導入口d30)は、第2導入部d2の第2導入口d20よりも、第2処理用面2において、下流側に位置する。図6-8、図10においては、図面が煩雑になるのを避けるため、第1導入部d1はその記載を省略している。この点については、第1導入部d1が設けられていない位置の断面と考えればよい。なお各流路は、密閉されたものであり、液密(被処理流動体が液体の場合)、気密(被処理流動体が気体の場合)とされている。
次に本発明の実施に用いる流体処理装置Fの要部である、下流側処理空間81内におけるさらなる流体の処理(下流側処理)に関して説明する。
第1処理用部10を収容するために、回転する第1処理用部10の外側にアウターケーシング61を設ける。アウターケーシング61は、上流側流出口4から排出された流体を受容する。本実施の形態においては、アウターケーシング61は、第1処理用部10と第2処理用部20の一部とを収容するもので、第1処理用部10の上流側流出口4から流出した流体は、アウターケーシング61の内面と第1処理用部10の外面との間の下流側処理空間81にて下流側処理がなされる。
この上下動のための構成は種々変更して実施することができるが、これに適する構造の一例を示せば、アウターケーシング61は、底部62と、底部62の周囲から上方に伸びる周壁部63とを備え、周壁部63の上端には、周壁部63から径方向外側に突出するフランジ67が全周に渡って形成されている。本実施形態においては、周壁部63には、その厚さが薄い薄肉部64とその厚さが厚い厚肉部65と両者の境界である境界部66を備え、底部62の中央に流出部68を備える。本実施形態においては、周壁部63の厚みにより薄肉部64と厚肉部65とを備えたが、周壁部63の厚みは一定であってもよい。また、フランジ67は、周方向の一部分にのみ形成してもよく、フランジ67をアウターケーシング61に備えなくてもよい。流出部68は、下流側処理空間81を流れる流体を系外(装置外)に排出するための排出口である。
上述のように、第2ホルダ22にアウターケーシング61を取り付けることによって、(a)第1、2処理用部10、20の外周面11、21とアウターケーシング61の周壁部63(肉厚部65)の内周面70との間と、(b)第1処理用部10の外端面12とアウターケーシング61の底部62の内面71との間に、下流側処理空間81を設けることができる。なお、この第1処理用部10の外端面12は、第1処理用部10の下面(言い換えれば第1処理用面1とは軸方向において反対側の面)である。
この実施の形態においては、回転する第1処理用面1と一体的に回転する第1処理用部10が回転部材であり、第1処理用部10の外周面11と外端面12は、下流側処理空間81を構成する壁部の一部を構成する。言い換えれば第1処理用部10が全体として円柱状をなす円柱部を構成し、その外面とアウターケーシング61の内面との間が下流側処理空間81を構成し、外面と内面の間で下流側処理がなされる。
流出部68は、底部62に開口するものに限らず、例えば、周壁部63に開口するものであってもよい。また、複数個の流出部68を設けてもよく、複数個の流出部68を設けることによって、下流側処理空間81内の流体の滞留時間に応じた流体の流出入を可能とする。
さらに、後述する図12(A)に示される実施の形態に示すように、流体を下流側処理空間81に供給するための導入装置(図示無し)を備え、その導入部69をアウターケーシング61内に配置してもよい。導入部69から下流側処理空間81に供給される流体に含まれる物質の一例として、原料そのものや重合開始剤、反応停止剤、重合停止剤、pH調整剤、触媒、コーティング剤などが挙げられる。
アウターケーシング61は、取付位置調整機構(図示せず)により上下方向(回転の軸方向)に移動可能に備えてもよい。アウターケーシング61を上下方向(回転の軸方向)に移動可能に備えることにより、下流側処理空間81の容積を増減することができ、下流側処理空間81内の流体の滞留時間を制御することができる。取付位置調整機構の具体的構成は、特に限定されるものではなく、ネジによる送り機構、エアーや油圧などの流体圧駆動機構など、直線的な送り手段を適宜選択して採用することができる。
下流側処理空間81に撹拌用の凹凸を備えて、流体に対する撹拌機能を持たせてもよい。例えば、第1処理用部10の外周面11や第1処理用部10の外端面12に撹拌羽根を備えることができる。第1処理用部10の外周面11や第1処理用部10の外端面12に撹拌羽根を備えると、回転軸31の回転を利用して、上流側処理がなされた流体を撹拌羽根で撹拌することができる。撹拌羽根は、両処理用面1、2から両処理用部10、20の外側に排出された流体に対してせん断力を与えることができる種々の形態として実施することができ、例えば、プレート状の羽根やスクリュー型の羽根、また凹状に加工されたものでも良い。撹拌羽根の形状は、処理目的に合った吐出量(流出部68からの流出量)やせん断力により最適に選定される。
第1処理用部10の外周面11や外端面12、アウターケーシング61の周壁部63の内周面70や底部62の内面71などの下流側処理空間81を構成する壁部に、下流側処理空間81の流体の滞留時間を延ばすための、ラビリンスシール機構を備えてもよい。ラビリンスシールとは、半径方向または軸方向に間隙をもちながら流体の流れに対する抵抗を与える、漏れが最小のシールであって、周辺部のナイフ状構造や接触点が形成する迷路によって、通過する流体の膨張が次々と引き起こされるものをいう。
本実施形態においては、突起部73は、その基端から先端に向けてすぼまっている。突起部73の先端と第1処理用部10の外周面11との間には、処理物の粘度にもよるが0.01mmから1mm程度の微小な間隙を有する。また、アウターケーシング61の底部62を周壁部63に設けた流出部68に向けて傾斜したものとしてもよい。
このように微小な間隙に設定されることによって、流体はそこを通過する際に層流状となり、通過が困難となる。その結果、この微小な間隙を通過するために時間を要することとなり、微小な間隙より上流側の比較的広い空間内に流体が滞留することになる。
言い換えれば、本発明の実施に用いる流体処理装置Fに適用されるラビリンスシール機構は、完全に漏れのないシール機構ではなく、その上流側の空間に流体を滞留させながら徐々に流体を下流側へ漏らしていく機構であると言える。
具体的には、更に他の実施の形態として、図6に示すものを挙げることができる。この実施の形態では、第1処理用部10の外端面12に、底部材91を備え、底部材91の下面93から下流側処理空間81に向けて下方向に突出する複数の突起部94を備えた形態を示すことができる。底部材91は、第1処理用部10と同体に回転するように第1処理用部10に取り付けられる。本実施形態においては、複数の突起部94はその基端から先端に向けてすぼまっている。突起部94の先端とアウターケーシング61の底部62の内面71と間には、0.01mmから1mm程度の微小な間隙を有する。本実施形態においては、(a)第1、2処理用部10、20並びに底部材91の外周面11、21、92とアウターケーシング61の周壁部63(肉厚部65)の内周面70との間と、(b)底部材91の下面93とアウターケーシング61の底部62の内面71との間に、下流側処理空間81を設けることができる。この実施の形態においては、第1処理用部10と底部材91とが回転部材であり、第1処理用部10の外周面11と底部材91の外周面92と下面93とが下流側処理空間81を構成する壁部の一部を構成する。本実施形態においては、底部材91を第1処理用部10とは別部品として作製し、第1処理用部10と同体に回転するように第1処理用部10に取り付けたが、底部材91は、第1処理用部10を直接加工して形成するなど、第1処理用部10と完全な同体として構成してもよい。また、図6に示すように、下流側処理空間81の深さを径方向外側から内側に向けて深くなるようアウターケーシング61の底部62の内面71を円錐形状のロート状としてもよい。
第1処理用部10の外周面11と底部材91の外周面92と下面93とが下流側処理空間81を構成する壁部の一部を構成する。
下流側処理空間81は、シール部84とプール部83とを備える。シール部84は、突出部16の先端とアウターケーシング61の周壁部63(肉厚部65)の内周面70との間に形成される狭隘な空間であり、プール部83は、第1処理用部10の突起部16のない外周面11とアウターケーシング61の周壁部63(肉厚部65)の内周面70との間に形成される空間であって、シール部84の上流側に配置され、シール部84よりも広い空間である。
特に、プール部83とシール部84を複数組設けることによって、装置全体における流体の滞留時間が平準化する。例えば、単一のプール部83によって、装置全体で予定する流体の総貯留容量を、満たすようにした場合を考えると、この単一のプール部83が空の状態からこれが満杯となるまでの滞留時間は一定であるとしても、満杯となった以降も連続運転をしていく場合には、単一のプール部83を満たした全ての流体が上流から流れ込んでくる新たな流体に全て入れ替わるように構成することは困難であり、一部の流体は上記の滞留時間に至らないまでに下流へ流出して、他の一部の流体はいつまでもプール部83内で滞留する。したがって、この滞留時間の制御は、偶然が支配する可能性が大きくなり、その結果、予定された所定の滞留時間に至らないまでに下流へ流出してしまう流体の割合も偶然が支配することになる。これに対して、プール部83とシール部84を複数組設けた場合には、一つあたりのプール部83での滞留時間は偶然が支配したとしても、設ける組数を多くしていくことによって、それぞれの流体の滞留時間が平準化していくことになり、滞留時間の安定的な制御の点で有利となる。
この実施の形態では、回転軸31に取り付けられた第1処理用部10が第2処理用部20に対して回転する。従って、第1処理用部10が回転部材である。回転軸31は、第1処理用部10を貫通する空洞に配置され、第1処理用部10の頂部17の中心にネジなどの固定具32によって固定される。回転軸31の基端は回転駆動機構Mの駆動軸と接続され、回転駆動機構Mの駆動力を第1処理用部10に伝えて第1処理用部10を回転させる。この回転を円滑に軸支するために、回転支持部34が、その外周に配置され、その先端側と基端側で回転軸31を回動可能に軸支する。
この機械的なクリアランス設定の構造での実施では、両処理用面1、2は、接近及び離反するものではなく、固定された間隔を有するものとして実施することができる。
機械的なクリアランス設定の構造の例とすれば、図示しないが、両処理用面1、2の間隔を測定可能なセンサーで測定し、その測定結果に基づいて、クリアランス調整機構を用いて第2処理用部20を軸方向へ移動させるよう構成してもよい。クリアランス調整機構の具体的構成は特に限定されるものではなく、ネジによる送り機構、エアーや油圧などの流体圧駆動機構など、直線的な送り手段を適宜選択して採用することができる。
導入部69は、上流側処理及び/又は前記下流側処理において発生するガスを排出する排出口と兼用させてもよく、排出口を別途設けてもよい。
したがって、上流側流出口4から流出した流体は、必要に応じて導入部69を通じて、流体の導入や気体などの流体の排出が行なわれながら、流出部68から排出されることにより、制限された下流側処理空間81にての下流側処理が完了するものである。
ラビリンスシール機構の例ではないが、更に他の実施の形態としては、図8に示すように、第1処理用部10の外端面12に、底部材91を備え、底部材91の下面93から下流側処理空間81に向けて下方向に突出する櫛歯状の突起部96と、アウターケーシング61の底部62の内面71から下流側処理空間81に向けて上方向に突出する櫛歯状の突起部74とを備え、突起部96と突起部96との間に突起部74を受容し、突起部74と突起部74との間に突起部96を受容するように配置した形態を示すことができる。底部材91は、第1処理用部10と同体に回転するように第1処理用部10に取り付けられる。このような配置とすることにより、突起部96と突起部74との間を通過する流体に対してせん断力を付与することができる。より詳しくは、底部材91が第1処理用部10と同体に回転することにより、底部材91に設けられた櫛歯状の突起部96が回転し、回転する櫛歯状の突起部96が櫛歯状の突起部74と突起部74との間を通過する際に、突起部96と突起部74との間の微小な間隙において被処理流動体に対してせん断力を付与することができる。突起部96と突起部74との間を通過する流体に効率よくせん断力を付与するために、突起部96と突起部74との間のクリアランスは0.1mmから1mm程度が望ましい。また、櫛歯状の突起部96の先端とアウターケーシング61の底部62の内面71と間には、0.5mmから2mm程度の微小な間隙を有し、櫛歯状の突起部74の先端と底部材91の下面93と間には、0.5mmから2mm程度の微小な間隙を有する。櫛歯状の突起96と74について、図8においては、中心線の左側には両者がオーバーラップしているものを描き、中心線の右側には両者がオーバーラップしていないものを描いている。図9に、最も径方向外側に設けられた一組の櫛歯状の突起部96aと櫛歯状の突起部74aとを取り上げた説明図を示す。理解しやすくするために、アウターケーシング61について、底部62の内面71と櫛歯状の突起部74aのみを描いている。
上流側処理がなされたがなされた流体は、上流側処理空間3の下流端から排出される。上流側処理空間3の下流端から排出された流体は、アウターケーシング61に受容され、下流側処理空間81を流れながら下流側処理として反応を進行させ反応生成物を得る処理がなされ、流出部68から系外(装置外)に排出される。
回転部材である第1処理用部10や底部材91は回転しているため、下流側処理空間81を流れる流体が下流側処理空間81を満たしている場合には、径方向外向きに遠心力が作用する。この遠心力の作用により、下流側処理空間81内の流体の滞留時間を制御する。
アウターケーシング61は、単一の部材または複数の部材を組み合わせて構成することができ、その材質は、各種の金属の他、シリコンカーバイド(SiC)などのセラミックスや焼結金属、耐磨耗鋼、サファイア、その他金属に硬化処理を施したものや、硬質材をライニングやコーティング、メッキなどを施工したものなど、第1、第2処理用部10、20と同等の材質のものを採用することができる。また、底部材91においては、ステンレスやチタンなどの金属やポリテトラフルオロエチレン(PTFE)、ポリエーテルエーテルケトン(PEEK)などの樹脂など加工のしやすい材質を選択して用いることができる。
第1処理用部10、底部材91やアウターケーシング61には、その少なくともいずれか1つに温度調整機構Tを組み込み、冷却或いは加熱して、部材の温度を調整するようにしてもよい。それによって、下流側処理空間81を流れる流体の温度を調整することができる。図1、図4-8、図10、図12-15に示す実施形態において、温度調整機構Tとしてアウターケーシング61に氷水やスチームを含む各種の熱媒体を流す温度調整ジャケットを設けている。熱媒体に替えて、冷却素子や発熱素子をその少なくともいずれか1つの部材に取り付けてもよい。
第1処理用部10、底部材91やアウターケーシング61は、少なくとも何れか1つにマイクロウェーブを照射する為の、マグネトロンなどのマイクロ波発生装置をマイクロウェーブ照射機構として備え、下流側処理空間81を流れる流体の加熱、化学反応の促進を行ってもよい。
第1処理用部10、底部材91やアウターケーシング61に、下流側処理空間81を流れる流体の圧力を調整するために、圧力調整機構を備えてもよい。例えば、圧力調整機構として、種々のポンプを用いることができる。下流側処理空間81に負圧をかけてもよい。具体的には、窒素ガスを用いて下流側処理空間81を加圧状態としたり、真空ポンプによる下流側処理空間81の真空度を制御することが挙げられる。
本発明の流体処理装置を用いて、上流側処理と下流側処理とを行うことによって、反応場の温度条件、圧力条件や撹拌条件、反応時間といった反応条件を調整することができることから、例えば、原料の反応率、選択率、生成物の収率といった処理特性の制御を行うことができるものであり、原料の反応率は、供給された原料に対する反応により消費された原料の割合であり、選択率は、反応により消費された原料が目的生成物の生成に消費された割合であり、生成物の収率は反応率と選択率とを乗じたものである。
本発明においては、上流側処理空間3内での上流側処理を層流条件下で行い、下流側処理空間81内での下流側処理を非層流条件下で行うことが好ましい。上流側処理空間3内で薄膜流体となっている第1流体に対して第2流体を層流条件下で合流させ、層流条件下で分子拡散による被処理流動体の均質な混合を行わせることが好ましい。上流側処理空間3の下流端から排出された流体は、両処理用面1、2による強制から解放され、より広い下流側処理空間81へと排出される。これに対し、上流側処理空間3の下流端から下流側処理空間81へ排出された流体に対してせん断力を付与したり上述の式(2)に記載の代表長さLを大きくするなどして乱流状態とし、流体中の分子同士が接触したり衝突したりする頻度を増加させることにより、生成物を得ることもできる。例えば、上流側処理空間3において有機反応により有機顔料粒子を生成させた後、その顔料粒子を分散させたい場合に乱流条件下での撹拌は有用である。また、乱流条件下では、温度調整機構Tを流れる熱媒体と下流側処理空間81を流れる流体との熱交換率のアップが期待できる。
流体処理装置Fを用いて、上流側処理を層流条件下で行うことで、上流側処理部で分子拡散により被処理流動体に含まれる反応物質を分子レベルで即座に混合することができる。そして、流体処理装置Fを用いて、上流側処理に引き続いて下流側処理を行うことで、層流条件下で上流側処理が行われた被処理流動体が、下流側処理部での反応に必要な反応条件、例えば反応場の温度条件、圧力条件や撹拌条件を保ったまま長時間被処理流動体を保持することができる。従って、流体処理装置Fは、短時間で反応を完了させることが困難な、付加反応、重合反応、縮合反応、加溶媒分解等の有機反応を行うのに好適な装置である。
また、第1処理用部10の回転数を高めてレイノルズ数を上げることで、上流側処理空間内を流れる被処理流動体にせん断力を加えてもよい。例えば、流体処理装置Fを用いて乳化重合を行う際、上流側処理部で乳化工程を行い下流側処理部で重合工程を行うが、上流側処理空間内を流れる互いに相溶しない被処理流動体にせん断力を加えることで、効率よく乳化させることができる。
本発明に係る有機化合物の製造方法の実施に適した連続撹拌装置Fについて、図16~図20を参照して、説明する。この形態は、上述の流体処理装置Fの上流側処理部を取り払って、下流側処理部のみで下流側処理を行うものである。下流側処理は有機反応の処理である。
外壁161は、図16(A)に示すように、全体として円筒状をなし、必要に応じて底部や天部を有するものとして実施され得る。本実施の形態においては、外壁161は円筒壁163であって、その両端には、円筒壁163から径方向外側に突出するフランジ167が形成されている。外壁161とは別部材である天部176又は底部162とフランジ167、167とが固定されることによって、円筒壁163の両端が閉鎖されている。
内壁110は、図16(A)に示すように、全体として柱状をなす。本実施の形態においては、内壁110は円柱状であって、その外周面111から径方向外側に突出する複数の突起部116を備える。突起部116は、平面視円周状をなし、軸方向において所定の間隔をあけて設けられている。図16(B)は、連続撹拌装置Fの要部説明図であって、内壁110と突起部116と後述する撹拌羽根211との配置を示す斜視図であり、上方の他の突起部116がない状態を描いている。図16(B)に示すように、突起部116は全体が厚みの等しい円盤状である。突起部116は径方向において厚みが変化するものであってもよい。
突起部116に換えて又は突起部116とともに、外壁161の円筒壁163の内周面170から径方向内側に突出する突起部を設けてもよく、底部162の内面171や天部176の内面から処理空間181に向けて突出する突起部を設けてもよい。
内壁110は外壁161の内側に配置され、外壁161と内壁110とは同心に配置される。外壁161と内壁110との間に処理空間181が形成される。本実施の形態においては、内壁110の外周面111と外壁161の円筒壁163の内周面170との間に、処理空間181を備える。この処理空間181内で被処理物の処理が行われる。被処理物とは、処理空間181内で流体の処理を予定する流体をいい、以下、被処理物を流体とも記載する。本発明において、被処理物には少なくとも1種類の有機化合物が含まれる。外壁161と内壁110との間に処理空間181を設けることができれば、外壁161と内壁110とは同心に配置しなくてもよい。
外壁161には供給部175と流出部168とを備える。供給部175は処理空間181内で流体の処理を予定する流体である被処理物を系外(装置外)から処理空間181へ供給するための供給口であり、その一端は被処理物を貯留するタンクなどの連続撹拌装置Fの外部に接続され、他端は処理空間181に直接又は間接に連通している。本実施の形態においては、図16(A)に示すように、供給部175は外壁161に設けられ、次に述べる受け入れ部182を介してシール部184に連通する。流出部168は、処理空間181で流体の処理がなされた処理物を系外(装置外)に排出するための排出口である。本実施の形態においては、図16(A)の上方が被処理物の流れの上流側であり、図16(A)の下方が被処理物の流れの下流側であって、供給部175は外壁161の円筒壁163の上方に設けられ、流出部168は外壁161の円筒壁163の下方に設けられている。供給部175と流出部168とを外壁161に複数備えてもよい。供給部175を外壁161に複数備えることにより、複数の被処理物を系外(装置外)から処理空間181に供給することを可能とし、流出部168を外壁161に複数備えることにより、処理空間181内の被処理物の処理時間に応じて処理空間181から系外(装置外)へ処理物の流出を可能とする。
内壁110の外周面111や外壁161の円筒壁163などの処理空間181を構成する部材に、処理空間181の流体の滞留時間を延ばすための、ラビリンスシール機構を備えてもよい。ラビリンスシールとは、半径方向または軸方向に間隙をもちながら流体の流れに対する抵抗を与える、漏れが最小のシールであって、周辺部のナイフ状構造や接触点が形成する迷路によって、通過する流体の膨張が次々と引き起こされるものをいう。
このように微小な間隙に設定されることによって、被処理物はそこを通過する際に層流状となり、通過が困難となる。その結果、この微小な間隙を通過するために時間を要することとなり、微小な間隙より上流側の比較的広い空間内に被処理物が滞留することになる。
言い換えれば、本発明の実施に用いる連続撹拌装置Fに適用されるラビリンスシールは、完全に漏れのないシールではなく、その上流側の空間に流体を滞留させながら徐々に流体を下流側へ漏らしていく機構であると言える。
処理空間181は、シール部184とプール部183とを備える。シール部184は、突出部116の先端と外壁161の円筒壁163の内周面170との間に形成される狭隘な空間であり、プール部183は、内壁110の突起部116のない外周面111と外壁161の円筒壁163の内周面170との間に形成される空間であって、シール部184の上流側に配置され、シール部184よりも広い空間である。
連続撹拌装置Fにおいて、ラビリンスシールとはシール部184をいい、ラビリンスシール機構とは一組のシール部184とプール部183をいう。
本実施の形態のように、内壁110が外壁161に対して回転し、内壁110の外周面111に突起部116を設け、突起部116の先端と外壁161の円筒壁163の内周面170との間にシール部184を設けることが、被処理物の齢を制御する点で理想的である。
特に、プール部183とシール部184を複数組設けることによって、装置全体における流体の滞留時間が平準化する。例えば、単一のプール部183によって、装置全体で予定する流体の総貯留容量を、満たすようにした場合を考えると、この単一のプール部183が空の状態からこれが満杯となるまでの滞留時間は一定であるとしても、満杯となった以降も連続運転をしていく場合には、単一のプール部183を満たした全ての流体が上流から流れ込んでくる新たな流体に全て入れ替わるように構成することは困難であり、一部の流体は上記の滞留時間に至らないまでに下流へ流出して、他の一部の流体はいつまでもプール部183内で滞留する。したがって、この滞留時間の制御は、偶然が支配する可能性が大きくなり、その結果、予定された所定の滞留時間に至らないまでに下流へ流出してしまう流体の割合も偶然が支配することになる。これに対して、プール部183とシール部184を複数組設けた場合には、一つあたりのプール部183での滞留時間は偶然が支配したとしても、設ける組数を多くしていくことによって、それぞれの流体の滞留時間が平準化していくことになり、滞留時間の安定的な制御の点で有利となる。
これらを調整することによって、生成物に応じて目的の滞留時間を実現する。
外壁161や天部176には導入部169を備えてもよい。導入部169は、供給部175から処理空間181へ供給される被処理物とは別経路から、処理空間181に被処理物を供給するための供給口である。本実施の形態においては、導入部169は供給部175と流出部168との間の外壁161に設けられ、処理途中の被処理物に対して他の被処理物を供給するものである。導入部169は、外壁161の円筒壁163の上端に設けてもよく、その位置を変更してもよい。導入部169から処理空間181へ供給される被処理物は、供給部175から処理空間181に供給される被処理物とは、被処理物自体を比べると異なるものでもあっても構わないし同一のものであっても構わない。導入部169から処理空間181に供給される被処理物の一例として、原料そのものや重合開始剤、反応停止剤、重合停止剤、pH調整剤、触媒、コーティング剤などが挙げられる。
導入部169は、流体の処理において発生するガスを排出する排出口と兼用させてもよく、ガスを排出する排出口を別途設けてもよい。
したがって、供給部175から処理空間181に供給された被処理物は、必要に応じて導入部169を通じて、被処理物の導入や気体などの流体の排出が行なわれながら、流出部168から排出されることにより、制限された処理空間181にて流体の処理が完了するものである。
外壁161と内壁110とのうちの少なくとも何れか1つに温度調整機構T10を備え、冷却或いは加熱して、部材の温度を調整することによって、処理空間181を流れる流体の温度を調整してもよい。図16(A)では、温度調整機構T10として、氷水やスチームを含む各種の熱媒体を流すための温度調整ジャケットを外壁161の円筒壁163の外周面に取り付けている。図16(A)に示すように、1つの温度調整ジャケットを外壁161に備えてもよく、後述する図20(A)に示すように、複数の温度調整ジャケット(図20(A)ではT11とT21の2つ)を外壁161に備えてもよい。また、図20(A)に示すように、複数の温度調整ジャケットを外壁161に備えた場合、これらのジャケットを同じ温度に調整してもよく、異なる温度に調整してもよい。複数の温度調整ジャケットを異なる温度に調整することで、処理空間181での流体の処理の進行に応じて処理空間181を流れる流体の温度を調整することができる。温度調整ジャケットに替えて、冷却素子や発熱素子を外壁161と内壁110とのうちの少なくとも何れか1つに取り付けてもよい。
内壁110には撹拌羽根211やスクレーパ212を備えてもよい。高粘性の被処理物の流体の処理を行う際に効果的である。
本実施形態においては、図16(A)(B)に示すように、内壁110に設けられた突起部116と突起部116との間の突起部116のない外周面111に複数枚の板状の撹拌羽根211を周方向に間隔をあけて備える。撹拌羽根211は内壁110の外周面111に固定されていてもよいし、円盤状の突起部116に固定されていてもよい。内壁110とともに撹拌羽根211が回転することにより、処理空間181を流れる被処理物への撹拌機能を高めることができる。撹拌羽根211に着脱自在に別個の羽根を取り付けてもよい。
また、本実施の形態においては、図16(A)に示すように、内壁110に設けられた突起部116と突起部116との間にスクレーパ212を備える。図17(A)は、図16(A)のA-A線に沿う要部断面図であり、(B)は図17(A)のB-B線に沿う要部断面図である。図17(A)(B)に示すように、突起部116と突起部116との間にスクレーパ212を支持するための柱部213を設ける。図17(A)に示すように、柱部213は2枚の板状部材であって、2枚の板状部材の間にスクレーパ212を挟みスクレーパ212と2枚の板状部材とをボルト214などで固定することによって、柱部213がスクレーパ212を支持する。図17(A)(B)に示すように、スクレーパ212の先端を外壁161の円筒壁170の内周面170に密着させる。
スクレーパ212は外壁161の円筒壁163の内周面170に付着した付着物を掻き取る、掻き取り羽根である。内壁110に設けられた柱部213にスクレーパ212を固定し、スクレーパ212の先端と外壁161の円筒壁163の内周面170とを密着させ、内壁110とともにスクレーパ212が回転することにより、スクレーパ212が付着物を連続して掻き取る。
外壁161の円筒壁163の外周面に温度調整機構T10を取り付け、処理空間181内を流れる被処理物の温度を調整しながら重合反応などの流体処理を行う場合、外壁161の円筒壁163の内周面170に付着物が発生すると、伝熱面となる内周面170の伝熱効率が著しく低下し、処理空間181内の流体の温度が調整できなくなる。スクレーパ212が付着物を連続して掻き取ることにより、外壁161の円筒壁163の内周面170の伝熱効率が低下することを防ぐとともに、生成物の収率の向上を図る。
また、この実施の形態においては、内壁110は六角柱状であって、その外周面111から径方向外側に突出する複数の突起部116を備える。内壁110は、円柱状や六角柱状、四角柱状など角柱状であってもよく、異形柱状であっても構わない。
なお、それぞれの実施の形態は、先の実施の形態と組み合わせて実施することができる。
内壁110や外壁161は、単一の部材または複数の部材を組み合わせて構成することができ、その材質は、各種の金属の他、シリコンカーバイド(SiC)などのセラミックスや焼結金属、耐磨耗鋼、サファイア、その他金属に硬化処理を施したものや、硬質材をライニングやコーティング、メッキなどを施工したものを採用することができる。
次に、図20(A)を参照して、連続撹拌装置Fの変形例について説明する。なお、以下の説明においても連続撹拌装置Fの基本的な構造や作用は同じであり、異なる部分を中心に説明するが、説明のない点については、前記の実施の形態の説明がそのまま適用されるものとする。この変形例にあっても、ラビリンスシール機構を備えその機能を奏する。
内壁110は、円錐台筒状であって、その外周面111から径方向外側に突出する複数の突起部116を備える。本実施の形態においては、突起部116は、平面視円周状をなし、軸方向において所定の間隔をあけて設けられ、突起部116の基端から先端に向けてすぼまっており、径方向において厚みが変化するものである。内壁110は中実の円錐台形状であってもよい。
外壁161と内壁110とのうちの少なくとも一つを間隙調整機構(図示せず)により移動可能に備えてもよい。外壁161と内壁110とのうちの少なくとも一つを移動可能に備えることにより、シール部184の広さを調整可能としている。この実施の形態においては、内壁110を間隙調整機構(図示せず)により同心上で即ち中心軸方向に移動可能に備える。中心軸の位置が変化しないことが好ましい。内壁110を同心上で移動可能に備えることにより、シール部184の広さを調整可能としている。この実施の形態においては、外壁161は円錐台筒状であり、内壁110を同心上で移動可能に備えることにより、突起部116の先端と外壁161の円筒壁163の内周面170との間の微小な間隙を調整可能としている。反応中に発生するガスを抜きたいときや高粘性の被処理物を処理する際にシール部184の広さを調整して比較的広いシール部184を備えることができ有利である。図20(B)(C)は、連続撹拌装置Fの要部説明図であって、内壁110を間隙調整機構(図示せず)により同心上で移動させた際のシール部の広さの変化を示す。実線で内壁110が下降している状態を描き、二点鎖線で内壁110が上昇している状態を描いている。なお、図20(C)は、円柱状である内壁110を間隙調整機構(図示せず)により同心上に移動させた際の要部断面図である。図20(B)(C)に示すように、内壁110を間隙調整機構(図示せず)により同心上で上昇させると、シール部184の広さが広くなる。間隙調整機構の具体的構成は、特に限定されるものではなく、ネジによる送り機構、エアーや油圧などの流体圧駆動機構など、直線的な送り手段を適宜選択して採用することができる。
外壁161や内壁110には、少なくとも何れか1つにマイクロウェーブを照射する為の、マグネトロンなどのマイクロ波発生装置をマイクロウェーブ照射機構として備え、処理空間181を流れる流体の加熱、化学反応の促進を行ってもよい。
内壁110や外壁161に、処理空間181を流れる流体の圧力を調整するために、圧力調整機構を備えてもよい。例えば、圧力調整機構として、種々のポンプを用いることができる。処理空間181に負圧をかけてもよい。具体的には、窒素ガスを用いて処理空間181を加圧状態としたり、真空ポンプによる処理空間181の真空度を制御することが挙げられる。
また、本発明に係る連続処理装置Fとは異なる装置を用いてプレ分散、プレ乳化、プレ粉砕などの前処理を行った流体に対する流体の処理を行ったり、前処理を行わずにダイレクトに流体の処理を行うなどの展開が可能である。
本発明の連続撹拌装置Fを用いて、流体処理を行うことによって、反応場の温度条件、圧力条件や撹拌条件、反応時間といった反応条件を調整することができることから、例えば、原料の反応率、選択率、生成物の収率といった処理特性の制御を行うことができるものであり、原料の反応率は、供給された原料に対する反応により消費された原料の割合であり、選択率は、反応により消費された原料が目的生成物の生成に消費された割合であり、生成物の収率は反応率と選択率とを乗じたものである。
本発明においては、処理空間181内での流体処理を非層流条件下で行うことが好ましい。供給部175から処理空間181へ供給された流体に対してせん断力を付与したり、上記の式(2)に記載の代表長さLを大きくするなどして乱流状態とし、流体中の分子同士が接触したり衝突したりする頻度を増加させることにより、生成物を得ることもできる。例えば、顔料粒子を含む流体を分散させて顔料分散液を得たい場合に乱流条件下での撹拌は有用である。また、乱流条件下では、温度調整機構T10を流れる熱媒体と処理空間181を流れる流体との熱交換率のアップが期待できる。
本発明における反応は、均一系の液相反応や、互いに混じり合わない液体同士の反応、液体-固体系又は液体-気体系の不均一系の反応でもよい。代表的には、反応基質となる有機化合物そのもの、または有機化合物を予め溶媒に溶解させた溶液の状態としたものおよび/または反応を促進させる物質(反応剤)そのもの、または反応を促進させる物質(反応剤)を予め溶媒に溶解させた溶液の状態としたものを、上述した図12(C)の流体処理装置Fに従って、第1導入部d1、第2導入部d2から導入し、強制的に均一に混合・撹拌して有機反応させる。また、反応基質と反応基質との反応時または反応基質と反応剤との反応時に、必要に応じて反応基質や反応剤とは異なる第3の成分を存在させても良い。第3の成分としては、重合開始剤、反応停止剤、重合停止剤、pH調整剤、触媒、コーティング剤等が挙げられ、反応時に複数の成分を存在させてもよい。
有機溶媒としては、ペンタン、ヘキサンなどの脂肪族系炭化水素、ベンゼン、トルエン、キシレン等の芳香族炭化水素、メタノール、エタノール、プロパノール、イソプロパノール等のアルコール類、エチレングリコール、プロパンジオール、ブタンジオール等のジオール類、アセトン、ジエチルケトン、メチルエチルケトン等のケトン類、ブチルアルデヒドなどのアルデヒド類、ジエチルエーテル、ジブチルエーテル、ジメトキシエタン、テトラヒドロフラン、ジオキサン等のエ-テル類、酢酸メチル、酢酸エチル、酢酸ブチル、γ-ブチロラクトン等のエステル類、トリエチルアミン、ピロリジン、ピリジンなどのアミン類、アセトニトリル等のニトリル類、ジメチルホルムアミド、N-メチルピロリドン等のアミド類、ジメチルスルホキシド等のスルホキシド類、四塩化炭素、クロロホルム、ジクロロメタン、ジクロロエタン等のハロゲン系溶媒、酢酸、蟻酸等のカルボン酸類、メタンスルホン酸等のスルホン酸類、が挙げられ、これらの任意の割合の混合物を用いることもできる。
超臨界流体としては、超臨界水、超臨界二酸化炭素などを用いることが出来る。
イオン液体としては、アンモニウム塩類、イミダゾリウム塩類、モルホリニウム塩類、ホスホニウム塩類、ピペリジニウム塩類、ピリジニウム塩類、ピロリジニウム塩類、スルホニウム塩類が挙げられ、これらの任意の割合の混合物を用いることもできる。
無機酸としては、硝酸、亜硝酸、硫酸、過硫酸、亜硫酸、チオ硫酸、アジチオン酸などの硫酸類、ホスホン酸、亜リン酸、リン酸、ポリリン酸などのリン酸類などがあげられ、これらの任意の割合の混合物を用いることもできる。
中でも、水と有機溶媒が好ましい。溶媒の使用量は、通常反応基質の濃度が、溶媒1リットルに対して0.01~20モル、好ましくは0.1~10モル、更に好ましくは1~5モルとなるような量の溶媒を用いるのがよい。
乳化重合は、安価で安全な水を媒体として用い、高い分子量のポリマーが得られ、0.01~数μmの幅広い範囲の粒子径を持つ微粒子が製造できることから広く普及した重合方法である。典型的な乳化重合では、モノマー、乳化剤もしくは分散剤、開始剤、水を用い、ラジカル重合を経てポリマー微粒子の水分散液を製造する。本発明の実施に用いる流体処理装置Fは、上流側処理部において相対的に回転する少なくとも二つの処理用面の間で被処理流動体にせん断力がかけられるため、互いに相溶しない二つの流体を上流側処理部を通過させることによって効率よく乳化させることができる。また、下流側処理部において一定時間反応を継続することができるため、連鎖重合のように同じ条件の維持が必要な反応に適している。例えば、図12(C)に示す装置を使用して乳化重合を行う場合、重合体原料として乳化重合に用いる各種原料を、第1流体、第2流体として調製し、それぞれ第1導入部d1、第2導入部d2から導入し、上流側処理部にて上流側処理としてモノマーの乳化工程または分散工程を実施し、下流側処理部にて下流側処理として被処理流動体に対して加熱撹拌処理を行うことにより重合工程を実施し、ポリマー微粒子の分散液を製造することが好ましい。上流側処理として一部重合が行われても構わないし、下流側処理として重合と並行してモノマーの乳化または分散が引き続き行われても構わない。第1流体、第2流体の例として、モノマーを少なくとも1つ含む流体と、モノマーと互いに混ざり合わない媒体である水に開始剤と乳化剤または分散剤を少なくとも1つ含む流体とが挙げられる。
エステル結合はプラスチック材料、繊維、医薬品などによくみられる基本的な結合であり、高分子を分解して再利用する際や、医薬品などで中間体の保護基を外して目的の官能基を結合させる場合などに、高分子や医薬品に含まれるエステル結合を分解することがある。加水分解反応はエステルをアルコールとカルボン酸に分ける反応であり、基本的な反応操作の一つである。酸性物質または塩基性物質によって触媒的に反応速度が増加することが知られている。典型的な加水分解の場合、エステル、水、触媒、溶媒を用いて、均一系、または不均一系で行われる。例えば図12(C)に示す装置を使用して、エステルの加水分解を行う場合、加水分解原料として用いる各種化合物を、第1流体、第2流体として調製し、それぞれ第1導入部d1、第2導入部d2から導入し、上流側処理部において上流側処理として混合工程を実施し、下流側処理部において下流側処理として被処理流動体に対して反応工程を実施することにより、アルコールとカルボン酸の混合液を得る。上流側処理として第1流体と第2流体との混合と反応がなされ、下流側処理において被処理流動体に対して反応状態を継続しても構わない。
第1流体、第2流体の例として、エステルを少なくとも1つ含む流体と、エステルの加水分解を促進する酸性物質または塩基性物質のいずれかを少なくとも1つ含む流体とが挙げられる。
反応例2の逆反応であり同じく有機化合物の合成にて多用される。ただし、エステル化反応またはアミド化反応の際に原料から脱離する水を適宜除去しないと逆反応によってエステル化反応またはアミド化反応の進行が阻害されるため、脱水剤等の試薬を必要に応じて併用する。特にカルボン酸自体の反応性が低い場合は、対応するカルボン酸塩化物などのカルボン酸ハロゲン化物、カルボン酸無水物等のカルボン酸等価体を使用することで反応性を改善することができ、取り扱いのしやすさからカルボン酸無水物を用いることが望ましい。また、エステル化反応またはアミド化反応を行う際は、必要に応じて反応を促進する物質(反応剤)を使用してもよい。典型的なエステル化反応またはアミド化反応の場合、アルコールまたはアミン、カルボン酸等価体、反応を促進する物質(反応剤)、溶媒を用いて、均一系、または不均一系で行われる。例えば図12(C)に示す装置を使用して、エステル化反応またはアミド化反応を行う場合、エステル化原料又はアミド化原料として用いる各種化合物を、第1流体、第2流体として調製し、それぞれ第1導入部d1、第2導入部d2から導入し、上流側処理部において上流側処理として混合工程を実施し、下流側処理部において下流側処理として被処理流動体に対して反応工程を実施することにより、目的とするエステルまたはアミドを得る。上流側処理として第1流体と第2流体との混合と反応がなされ、下流側処理として被処理流動体に対して反応状態を継続しても構わない。
第1流体、第2流体の例として、アルコールまたはアミンを少なくとも1つ含む流体と、カルボン酸、カルボン酸無水物、またはカルボン酸ハロゲン化物のうち少なくとも1つを含有する流体とが挙げられる。
脱水縮合反応にはいくつかの様式が存在するが、以下に説明するのはその中のひとつで活性メチレン化合物とアルデヒドまたはケトンとの縮合によりアルケンを得る反応(別名Knoevenagel縮合)である。また、脱水縮合反応を行う際は、必要に応じて反応を促進する物質(反応剤)を使用してもよい。典型的な脱水縮合反応の場合、活性メチレン化合物とアルデヒドまたはケトン、反応を促進する物質(反応剤)、溶媒を用いて、均一系、または不均一系で行われる。例えば図12(C)に示す装置を使用して、脱水縮合反応を行う場合、脱水縮合原料として用いる各種化合物を、第1流体、第2流体として調製し、それぞれ第1導入部d1、第2導入部d2から導入し、上流側処理部において上流側処理として混合工程を実施し、下流側処理部において下流側処理として被処理流動体に対して加熱撹拌処理を行うことにより反応工程を実施することで、目的とするアルケンを得る。上流側処理として第1流体と第2流体との混合と反応がなされ、下流側処理として被処理流動体に対して加熱撹拌処理を行うことにより反応状態を継続しても構わない。
第1流体、第2流体の例として、アルデヒド又はケトンと活性メチレン化合物をそれぞれ少なくとも1つずつ含む流体と、アルデヒドと活性メチレン化合物との反応又はケトンと活性メチレン化合物との反応を促進する物質を含む流体とが挙げられる。
アセタール化反応は、酸触媒存在下でアルデヒドまたはケトンとアルコールを縮合させてアセタールを得る反応、または、ビニルエーテルとアルコールを縮合させてアセタールを得る反応であり、樹脂や接着剤の中間体合成に用いられる。また、反応を行う際は、必要に応じて反応を促進する物質(反応剤)を使用してもよい。典型的なアセタール化反応の場合、アルコールと、アルデヒドまたはケトンまたはビニルエーテル、酸触媒、反応を促進する物質(反応剤)、溶媒を用いて、均一系、または不均一系で行われる。例えば図12(C)に示す装置を使用して、アセタール化反応を行う場合、アセタール化原料として用いる各種化合物を、第1流体、第2流体として調製し、それぞれ第1導入部d1、第2導入部d2から導入し、上流側処理部において上流側処理として混合工程を実施し、下流側処理部において下流側処理として被処理流動体に対して加熱撹拌処理を行うことにより工程を実施することで、目的とするアセタールを得る。上流側処理として第1流体と第2流体との混合と反応がなされ、下流側処理として被処理流動体に対して加熱撹拌処理を行うことにより反応状態を継続しても構わない。
第1流体、第2流体の例として、アルデヒドまたはケトンとアルコール類とを少なくとも1つずつ含む流体と、アルデヒドとアルコール類との反応またはケトンとアルコール類との反応を促進するプロトン酸触媒を含む流体とが挙げられる。
図12(C)に示す流体処理装置Fを用いた。あらかじめ原料液を作製し、原料液を貯蔵している容器(図示無し)から送液ポンプP1、P2を用いて第1導入部d1及び第2導入部d2から上流側処理空間3へ原料液を導入し有機反応させた。また、比較のため、下流側処理部を有さない従来型の装置として、本願出願人に係る特開2010-189661号公報の図1(A)に示されているものと同様の、エム・テクニック株式会社製の強制薄膜式リアクター(ULREA SS-11-75)を用いて、同様に送液ポンプP1、P2を用いて原料液を処理用面1、2間に導入し有機反応させた。本発明に係る有機化合物の製造方法の実施に用いる流体処理装置Fは、下流側処理を行うための下流側処理空間81を流体処理装置F内に設ける点において、特開2010-189661号公報に示されている装置と相違するものである。
乳化重合で得られた重合体(ポリマー)微粒子の分散液については、ゲル濾過クロマトグラフィーにより数平均分子量(Mn)、重量平均分子量(Mw)、及び分子量分布Mw/Mnの評価を行った。
