また、従来の不飽和イソシアネート化合物は、従来の判定方法では品質に大きな差が見られなくても、これを用いて不飽和化合物を製造した場合、製造中に急激に反応生成物の粘度が上昇したり、ゲル化したりする場合があった。このため、利用時の安定性を向上させることが要求されていた。
しかし、不飽和イソシアネート化合物に多くの重合防止剤を添加すると、これを原料として不飽和化合物を製造した場合に、不飽和化合物とともに、重合防止剤に起因する着色成分が生成されやすくなる(例えば、非特許文献1参照)。このため、製造した不飽和化合物が、着色されてしまう場合があった。

本実施形態の組成物は、気相部に露点-30℃以下の乾燥窒素ガスが充填された容器内に収容されていることが好ましい。このことにより、蒸留後の組成物中の化合物(A)と水分との接触が防止され、組成物中での化合物(B)の増加が抑制される。その結果、保管時の安定性および利用時の安定性の良好となる。
よって、本発明の組成物を用いて製造した不飽和化合物が、重合防止剤に起因する着色成分によって着色されることを防止できる。
また、本発明の組成物は、高い収率で製造できる。
本実施形態の組成物の製造方法は、容器内に収容された組成物を製造する方法である。
本実施形態の組成物の製造方法は、一般式(1)で示される化合物(A)と、一般式(2)で示される化合物(B)とを含み、化合物(A)100質量部に対して前記化合物(B)を2.0質量部超含有する混合物を製造する工程と、前記混合物を2.0~4.0の還流比、1.0~10.0kPaの圧力、90~140℃の蒸留温度で蒸留法により精製する。精製によって得られた精製物(組成物)の化合物(A)の含有量は、上述したように、好ましくは95.0質量%以上であるが、これのみに限定されない。化合物(A)100質量部に対して化合物(B)を2.0質量部超含有するとは、化合物(A)100質量部に対して化合物(B)を2.0質量部以上含有することを意味する。
化合物(A)と化合物(B)とを含み、化合物(A)100質量部に対して化合物(B)を2.0質量部超含有する混合物を製造する方法としては、任意に選択できるが、例えば、従来公知の化合物(A)の製造方法を用いて、化合物(A)を生成させると同時に化合物(B)を副生させる方法が挙げられる。
具体的には、例えば、以下の方法等が挙げられる。はじめに、不飽和カルボン酸クロリドとアミノアルコール塩酸塩との反応によって、不飽和カルボン酸アミノアルキルエステル塩酸塩を合成する。次いで、不飽和カルボン酸アミノアルキルエステル塩酸塩と塩化カルボニルとを反応させる。このことにより、化合物(A)である不飽和カルボン酸イソシアナトアルキルエステルを生成させる。それと同時に、化合物(A)と不飽和カルボン酸アミノアルキルエステル塩酸塩とを反応させて、不純物である化合物(B)を副生させる方法等が挙げられる。ただし、この方法のみに限定されない。
このようにして得られた化合物(A)と化合物(B)との混合物中には、一般的に、化合物(A)100質量部に対して前記化合物(B)が2.0質量部超含まれている。
なお前記混合物に含まれる化合物(B)の量の上限は、任意に選択できる。例えば、化合物(A)100質量部に対して、化合物(B)の量が10質量部以下であることが一般的であり、好ましくは8質量部以下であり、より好ましくは6質量部以下である。ただし、これらの例のみに限定されない。
また混合物中に含まれる化合物(A)の量は、任意に選択できるが、例えば、前記混合物中の化合物(A)の含有量は、例として55~85質量%であることが挙げられ、60~80質量%であってもよく、65~75質量%であることが好ましい。ただしこれらのみに限定されない。
<蒸留工程>
本実施形態においては、このようにして得られた化合物(A)と化合物(B)との混合物を還流比(還流量/留出量)2.0~4.0、圧力1.0~10.0kPa、蒸留温度90~140℃で、蒸留法により精製し、化合物(A)を低沸成分として回収する。このことにより、化合物(A)100質量部に対する化合物(B)の含有量が0.00002~2.0質量部である精製物を得る。化合物(A)は、通常は液体であるので溶媒は不要である。
混合物に添加した重合防止剤は、蒸留を行うことにより一部除去される。蒸留後に組成物中に残留する重合防止剤は、組成物の保管中および輸送中に組成物がゲル化することを防止し、組成物の保管時の安定性の向上に寄与する。重合防止剤は、必要に応じて、蒸留後に得られた組成物に添加してもよい。
減圧ブレーク工程時の蒸留装置内は、精製物中で化合物(B)が生成されやすい条件となっている。本実施形態では、減圧ブレーク工程において、蒸留後の蒸留装置内に露点-30℃以下の乾燥窒素ガスを供給し、蒸留装置内の圧力を大気圧に戻すため、蒸留後の精製物中の化合物(A)と水分との接触を防止できる。しかも、本実施形態では、充填工程において、容器内の気相部に露点-30℃以下の乾燥窒素ガスを充填するので、容器に収容した組成物中での化合物(A)と水分との接触も防止できる。したがって、減圧ブレーク工程および充填工程を行うことで、組成物中で化合物(B)が生成したり、増加したりすることを防止できる。よって、保管時の安定性および利用時の安定性が良好となる。
本実施形態では、より効果的に精製物中での化合物(B)の増加を防ぐために、蒸留後の蒸留装置内の精製物を容器に送り込む工程において、精製物が露点-30℃以下の乾燥窒素ガス以外の気体と接触しないことが好ましい。
本実施形態の不飽和化合物の製造方法は、上記の組成物と、活性水素を有する化合物とを混合し、組成物に含まれる化合物(A)と活性水素を有する化合物とを反応させて反応生成物(不飽和化合物)を得る工程を含む。
また、活性水素を有する化合物における活性水素は、窒素原子、酸素原子、硫黄原子等に結合した水素原子であり、炭素原子に結合した水素原子と比較して高い反応性を示す。
活性水素を有する化合物は、特に限定されるものではなく、不飽和化合物の構造に応じて適宜選択できる。
例えば、活性水素を有する化合物として、水酸基、メルカプト基、アミノ基(環状アミン、アミド、イミドを含む)、カルボキシ基等の、活性水素含有基を有する化合物を用いた場合、以下に示す反応により、以下に示す反応生成物(不飽和化合物)が得られる。
組成物に含まれる化合物(A)とメルカプト基を有する化合物とを反応させると、化合物(A)のイソシアナト基と、メルカプト基とが反応して、不飽和チオウレタン化合物が生成する。本実施形態において、不飽和チオウレタン化合物は、分子内にエチレン性不飽和結合およびチオウレタン結合を含む化合物を意味する。
組成物に含まれる化合物(A)とカルボキシ基を有する化合物とを反応させると、化合物(A)のイソシアナト基とカルボキシ基とが反応して、不飽和アミド化合物が生成する。本実施形態において、不飽和アミド化合物は、分子内にエチレン性不飽和結合およびアミド結合を含む化合物を意味する。
水酸基を有する化合物としては、上記の中でも、ポリオールが好ましく、脂肪族ポリオールがより好ましい。
メルカプト基を有する化合物としては、上記の中でも、ポリチオールが好ましく、脂肪族ポリチオールがより好ましい。
アミノ基を有する化合物としては、上記の中でも、ポリアミンが好ましく、脂肪族ポリアミンがより好ましい。
カルボキシ基を有する化合物としては、上記の中でも、ポリカルボン酸が好ましく、脂肪族・芳香族ポリカルボン酸がより好ましい。
活性水素を有する化合物としては、上記の中でも、汎用性の点で、ポリオール、ポリチオール、ポリアミンまたはポリカルボン酸であることが好ましく、ポリオールが特に好ましい。
イソシアナト基/活性水素の比は、従来、化合物(A)と活性水素を有する化合物との反応において適用されている比と同じであってよい。イソシアナト基/活性水素の比は、活性水素を有する化合物の種類によって異なる。
反応触媒としては、公知の反応触媒を用いることができる。反応触媒の具体例としては、ジブチル錫ジラウレート、ナフテン酸銅、ナフテン酸コバルト、ナフテン酸亜鉛、トリエチルアミン、1,4-ジアザビシクロ[2.2.2]オクタン、ジルコニウムアセチルアセトナート、チタンジイソプロポキシビス(エチルアセトアセテート)、ビスマストリス(2-エチルヘキサノエート)と2-エチルヘキサン酸の混合物、等が挙げられる。これらの反応触媒は、1種単独で用いてもよいし、2種以上を組み合わせて用いてもよい。
その他、前記反応に際し、目的に応じて、公知の光安定剤、紫外線吸収剤、酸化防止剤、染料充填剤、反応性希釈剤等の種々の物質を添加してもよい。
また、本実施形態の組成物は、化合物(A)100質量部に対して、化合物(B)を0.00002質量部以上含有するため、高い収率で製造できる。
また、本実施形態の組成物の製造方法では、精製工程において、蒸留後の蒸留装置内に露点-30℃以下の乾燥窒素ガスを供給し、蒸留装置内の圧力を大気圧に戻す減圧ブレーク工程と、蒸留後の蒸留装置内の精製物を容器に収容し、容器内の気相部に露点-30℃以下の乾燥窒素ガスを充填する充填工程とを行う。このため、蒸留後の精製物中の化合物(A)が水分と接触しにくく、精製物中で化合物(B)が増加しにくい。よって、本実施形態の組成物の製造方法によれば、保管時の安定性および利用時の安定性の良好な組成物が得られる。

組成物を下記の条件で内部標準法にてガスクロマトグラフィー(GC)分析することにより行った。
カラム:DB-1、注入口温度:300℃、検出温度:300℃
カラム温度:50℃→(10℃/min)→300℃

実施例1~12、比較例1~16の蒸留直後の液状の組成物100gを、透明なガラス容器に入れてから、窒素ガス雰囲気下、密封状態で、25℃で30日間保管し、保管後の外観を以下に示す方法により評価した。
組成物を入れた透明なガラス容器を、約45度の角度に数回傾け、目視により以下に示す規準で評価した。その結果を表1~表4に示す。
「基準」
変化なし:ガラス容器を傾けてから30秒未満で流れ落ちる。
水飴状:ガラス容器を傾けてから30秒以上180秒未満で流れ落ちる。
固化:ガラス容器を傾けてから180秒以上経過しても流動しない。
密封状態で、25℃で30日間保管した実施例1~12、比較例1~16の組成物の粘度を、JIS―Z 8803:2011に則り以下に示す方法により求めた。その結果を表1~表4に示す。
各組成物について、ウベローデ式粘度計を用いて25℃での動粘度(cm3/sec)を測定した。実施例1~6、比較例1~8については、動粘度の測定値に以下に示すカレンズMOI(登録商標)(昭和電工製)の密度を乗じて粘度(mPa・sec)を算出した。また、実施例7~12、比較例9~16については、動粘度の測定値に以下に示すカレンズAOI(登録商標)(昭和電工製)の密度を乗じて粘度(mPa・sec)を算出した。
(カレンズMOI(登録商標)の密度)1.096g/cm3(25℃)
(カレンズAOI(登録商標)の密度)1.133g/cm3(25℃)
これに対し、化合物(A)100質量部に対する化合物(B)の含有量が2.0質量部超含まれている比較例1~16の組成物では、25℃で30日間の保管することにより粘度が高くなりすぎて、粘度の測定ができなかった。また、比較例1~16の組成物では、外観評価が「水飴状」または「固化」となった。
