- the most important characteristics of the batch process are two points. One is that there is “stay” or “interruption” in the process, and the second is that the production of the products is spaced apart, that is, the product has a batch and only one fixed quantity of product can be obtained in one batch. That is, for each batch of production, a fixed amount of the raw materials is reacted in the order of the reaction steps, resulting in a limited fixed amount of product (product); then a fixed amount of the raw material is put, and the same step is followed. The batch reacted to produce a limited fixed product.
- each step in one reactor there are two ways to achieve a batch process: 1) using multiple reactors (eg, flasks, reactors, etc.), each step in one reactor; 2) using a reactor (eg, flask, reaction) In the reactor, etc., each step of the reaction is sequentially completed in the reactor, and a plurality of raw materials need to be sequentially added according to the progress of the reaction, that is, after each step of the reaction, there is a “stay”, waiting for further addition of the raw materials of the subsequent reaction. .
- Some literatures also refer to mode 2) as continuous, which is also intermittent in nature, because there is "stay” in the process, waiting for feeding, or adjusting to the appropriate temperature for the next reaction (for example, heating, cooling) Or keep warm).
- the first step oxidation process Whether using oxygen auto-oxidation method or hydrogen peroxide oxidation method, the batch process reactor has a large liquid holding capacity, and a single reaction requires a large amount of pure oxygen or hydrogen peroxide, so the batch process has great safety hazards.
- the third step of the condensation process is mostly exothermic, and the reactor needs to have good heat transfer performance to ensure that the reaction does not fly. Once the temperature is too high, the product will decompose and the yield will decrease.
- the existing batch process mainly controls the reaction temperature by controlling the addition rate of the oxidant (slow drop or slow aeration) in combination with the corresponding heat transfer device, so that the operation time is greatly prolonged and the production efficiency is lowered; A large amount of peroxide exists for a long time, and the process safety hazard is very large, and the process safety problem is not fundamentally solved. That is, intermittent process safety, product yield and quality stability are in urgent need of improvement.
- the amplification effect refers to the results obtained by using small equipment for chemical process (ie, small-scale) experiments (such as laboratory scale), and the results obtained under the same operating conditions with large-scale production devices (such as industrial scale). There are often big differences. The effect of these differences is called the amplification effect.
- the reason is mainly that the temperature, concentration, and material residence time distribution in small-scale experimental equipment are different from those in large-scale equipment. That is to say, under the same operating conditions, the results of small-scale experiments cannot be completely repeated on the industrial scale; if the results of the same or similar results as the small-scale experiments are obtained on the industrial scale, it is necessary to optimize the adjustment and change the process parameters and Operating conditions.
- the amplification effect is a difficult and urgent problem to be solved.
- Local production means that the manufacturer places the equipment in the nearest or same location for the end consumer (or downstream user), thus greatly reducing the number of products from the manufacturer to the end consumer (or downstream users).

- This large-scale and uncertain amplification effect will bring many disadvantages to the industrial application of the process. For example, when industrialization is amplified, only multiple steps of amplification can be adopted, and in order to achieve consistency with the laboratory scale.
- each process of amplification must be re-adjusted to optimize process conditions and parameters, which will greatly consume manpower and material resources and project development time; even if multiple step-by-step amplification is used, the magnification effect may be too large, which may eventually lead to amplification. Afterwards, the results of the laboratory scale cannot be achieved; at the same time, the large-scale uncertain amplification effect will affect the stability and reliability of the process, resulting in unstable product quality and difficult to control; in addition, it will bring potential safety to the production process. risk.
- the production time takes 3 to 18 hours, the reaction time is long, the production efficiency is low, and it is impossible to achieve on-line production, that is, ready to use.
- the existing processes all have different degrees of amplification effects, resulting in a large amount of manpower and material resources and a lot of uncertainty when industrialization is amplified; the process reliability after amplification also has problems, resulting in unstable product quality, difficult to control; and production

Description
本发明涉及化学领域,具体涉及一种由醇或烷烃直接制备有机过氧化物的在线全连续流生产工艺,所述的有机过氧化物为易燃易爆的化合物。
有机过氧化物是指过氧化氢中的氢原子被烷基、酰基、芳香基等有机基团置换而形成的含有-O-O-过氧官能团的有机化合物。特征是受热超过一定温度后会分解产生含氧自由基,不稳定、易分解。化工生产的有机过氧化物主要是用来作合成树脂的聚合引发剂、催化剂。在高分子材料领域,有机过氧化物用作自由基聚合的引发剂、接枝反应的引发剂、橡胶和塑料的交联剂、不饱和聚酯的固化剂以及纺丝级聚丙烯制备中的分子量及分子量分布调节剂。有机过氧化物是用于下面用途中自由基的来源:①乙烯基与二烯单体的自由基聚合和共聚合引发剂;②热固性树脂的硫化剂;③弹性体和聚乙烯的交联剂。
除上述高分子材料工业外,有机过氧化物作为光引发剂和增感剂用于胶片工业,用于感光性高分子材料,感光树脂等,也常用于环氧树脂的生产;医用材料方面,有机过氧化物与药物组成的引发剂,用于合成药物缓释给药基质(如微球、微丸、药膜);有机合成方面,有机过氧化物主要用作氧化剂和环氧化剂。另外,有机过氧化物还应用于医疗器械和食品的消毒、纺织品、纸张等日化工业的漂白剂、脱色剂、杀菌剂、清洗剂等。
过氧化羧酸酯和过氧化碳酸酯是重要的有机过氧化物,如过氧化~2~乙基己基碳酸叔丁酯、过氧化新癸酸异丙苯酯和过氧化新癸酸-1,1,3,3-四甲基丁酯。过氧化羧酸酯和过氧化碳酸酯是自由基聚合反应的低温引发剂,广泛用于聚乙烯(LDPE)、聚氯乙烯(PVC)、聚苯乙烯(PS)、苯乙烯共聚物(如,ABS)、聚甲基丙烯酸酯(PMMA)和聚醋酸乙烯酯(PVAc)等生产领域。同时,其也是不饱和聚酯的高温固化剂。而过氧化缩酮主要用于不饱和聚酯的交联剂、橡胶和塑料的引发剂。目前国内外市场对于过氧化羧酸酯、过氧化碳酸酯和过氧化缩酮需求越来越大,所以开发有机过氧化物的连续生产工艺具有现实意义和远大的前景。
有机过氧化物是非常活泼的化合物,极易分解为高反应活性的自由基和氧,该过程中会释放大量的热甚至引发爆炸。作为有机过氧化物,其重要特征是自加速分解温度(SADT),在等于或高于自加速分解温度下,有机过氧化物分解反应放热速率与环境散热速率是失衡的,即体系热量在不断累积,此时,有机过氧化物可通过热分解导致危险的自加速分解反应和在不利环境下的爆炸或起火。与不相容的物质接触以及提高机械应力可导致在等于或低于SADT下的分解。
有机过氧化物在温度的作用下会发生分解,这是由于存在可在约84~184kJ/mol的能量范围△H内打开的氧-氧键,所述能量范围取决于该有机过氧化物的性质。这就是说不同的有机过氧化物发生分解打开氧-氧键时所需的能量是因各自性质而不同的。因此,不同有机过氧化物,自分解加速温度和热稳定性会有很大差异。例如,过氧化羧酸酯类过氧化物过氧化新癸酸异丙苯酯(CNP)的自分解加速温度(SADT)为10℃,10小时半衰期对应的温度为38℃;过氧化新戊酸叔丁酯(TBPV)的自分解加速温度(SADT)为20℃,10小时半衰期对应的温度为57℃;过氧化新癸酸叔丁酯的自分解加速温度(SADT)则为15℃,10小时半衰期对应的温度为46℃;过氧化碳酸酯类过氧化物过氧化2-乙基己基碳酸叔丁酯(TBEC)自分解加速温度(SADT)则为60℃,10小时半衰期对应的温度为100℃;过氧化缩酮类过氧化物1,1-二(叔丁基过氧化)环己烷自分解加速温度(SADT)则为70℃,10小时半衰期对应的温度为94℃。同时由于结构差异,不同有机过氧化物的合成路线和所需原料都不同的,原料的物理、化学性质也千差万别。这众多差异导致不存在一个所谓“通用”的工艺过程能适用所有的有机过氧化物,导致不同的有机过氧化物的生产工艺难以相互移植套用。每个具体有机过氧化物的生产都需要根据其自加速分解温度和热稳定性以及使用原料的物理、化学性质来专门设计开发个性化的适用工艺过程、条件和参数。
现有技术制备过氧化羧酸酯、过氧化碳酸酯或过氧化缩酮包括以下两步反应:
第一步是氧化反应,醇或烷烃与氧化剂反应合成烷基过氧化物R(OOH)

化工产品的工业化生产过程的改进,主要指的是对工艺的改进。所述的工艺是指利用各种设备将原料进行加工或反应,得到最终产品的方法与过程,是化学反应或物理过程结合设备通过调整温度、压力、物料配比等技术参数得到产品的一个过程,也就是,生产工艺是指将化学反应或物理过程在工业化尺度实现的过程。生产工艺与反应并非一一对应关系,一个工艺可以包含一个反应,也可以包含多个反应。化学产品的制备过程包含的反应和对应的反应路线是由其反应机理所决定的,但对于相同的反应路线,可以由不同的生产工艺来实现。生产工艺优化改进可能达到的效果有:第一,提高生产效率,增加产能,降低生产成本;第二,改善工艺安全性;第三,提高产品质量;第四,降低“三废”排放。
工业化生产过氧化羧酸酯、过氧化碳酸酯或过氧化缩酮的过程中,氧化反应、缩合反应分别对应氧化工艺和缩合工艺。其中,氧化反应和缩合反应都是油水两相反应,反应效率低,反应体系中存在大量的水。第一步氧化反应所用的氧化剂为液体氧化剂(例如:双氧水)或气体氧化剂(例如:氧气),氧化反应带来的两个问题是:1)受氧化工艺所限,氧化剂必然无法全部转化,并且不可避免地会生成二烷基过氧化物,二烷基过氧化物、没有反应完全的氧化剂就成为了氧化工艺的杂质,必须要除去这些杂质才能进行下一步缩合反应。例如,使用双氧水作为氧化剂时,过氧化物杂质(二烷基过氧化物和双氧水)会直接影响最终产品(过氧化羧酸酯、过氧化碳酸酯、过氧化缩酮)的品质。由于不同有机过氧化物自加速分解温度和半衰期不同,使用有机过氧化物就是利用这不同的自加速分解温度和半衰期等特性,因此有机过氧化物一般不能混用,尤其是自加速分解温度和半衰期等相差很大的有机过氧化物更不能混用,否则会严重影响使用效果。例如,目标产物为过氧化新癸酸叔丁酯,过氧化新癸酸叔丁酯的SADT为15℃,10h半衰期对应的温度为46℃,制备过氧化新癸酸叔丁酯过程生成的二叔丁基过氧化氢的SADT为80℃,10h半衰期对应的温度为121℃,不同浓度双氧水的SADT和半衰期各不相同,常温下(通常为25℃)双氧水在淡水中的半衰期为8小时到20天,可见三者SADT和半衰期相差很大,三者混合物无法满足单一使用需求。因此在过氧化新癸酸叔丁酯的合成过程中,氧化反应后必须要去除二烷基过氧化物和双氧水,否则,会严重影响过氧化新癸酸叔丁酯的品质性能。2)大量的水和杂质会影响缩合反应浓度,进而影响反应速率,导致生产效率大大降低。而使用氧气作为氧化剂时其主要杂质是碳酸钠、引发剂和水,同样存在以上两个问题,一是引发剂通常为自由基引发剂如偶氮二异丁氰(SADT为50℃,10h半衰期分解温度为65℃)、二异丙苯过氧化氢(SADT为75℃,10h半衰期分解温度为117℃)等,如不除去混入最终产品中也会影响产品品质性能,二是水等杂质会影响反应速率,进而影响生产效率,如文献中提到高压釜中加入500g二异丙苯、200g水、20gNa
2CO
3和6g偶氮二异丁氰加压反应60h合成二过氧化氢二异丙苯,静止,分离水相得到上层油相才能进行下一步反应(新型交联剂双叔丁基过氧化二异丙苯的合成研究,化学世界,2008(1):38~41)。
现有合成过氧化羧酸酯、过氧化碳酸酯或过氧化缩酮的生产工艺中,氧化工艺后得到的产物为包含烷基过氧化物、杂质、大量的水的混合物,为了保证缩合工艺的有效进行,需经过纯化过程去除混合物中的杂质和大量的水,制得符合市售工业品标准的烷基过氧化物(如市售叔丁基过氧化氢要求如下:二叔丁基过氧化物≤0.08%,叔丁醇≤0.5%,其他有机物≤0.4%)。所述的纯化工艺可以是气液分离、酸碱法、减压精馏或蒸馏、闪蒸分离等,纯化过程通常采用的是间歇工艺,中国专利CN106588734中提到异丙苯过氧化氢提纯步骤包括气液分离、闪蒸分离和浓缩,中国专利CN102617432中提到合成叔丁基过氧化氢后静置分层得到上层有机相,向有机相中加入碱液反应温度10~50℃,反应时间0.5~4h,静置分层,去除上层有机相,下层水相和氯代酯进一步反应得到过氧化2-乙基己基碳酸叔丁酯。可见,制备不同的烷基过氧化物所需的纯化工艺不同,还需要单独的设备如精馏塔等,并且所需的设备也大多不同,现有工艺没有一种通用的设备和工艺能做到可以纯化各种烷基过氧化物。
同时,现有缩合工艺后得到的只是过氧化羧酸酯、过氧化碳酸酯或过氧化缩酮粗品,含有水、烷基过氧化物、盐等,还需进行后处理工艺后才能得到符合市售标准的产品(如市售过氧化新癸酸叔丁酯要求如下:氯离子含量≤0.05%,叔丁基过氧化氢含量≤0.1%),所述后处理工艺可以是分离、碱洗、水洗、减压精馏或蒸馏、闪蒸分离、干燥等,中国专利CN102558399中提到过氧化新癸酸叔丁酯的后处理方法为在反应结束后静置20-40min,分离母液,将反应生成物洗至pH值5~7,加入烷烃溶剂在0℃以下搅拌20-30min得到溶剂型过氧化新癸酸叔丁酯产品,后处理时间大于40min;中国专利CN102336694中提到1,1-二(叔丁基过氧化)环己烷的后处理方法为反应母液碱洗、水洗,得到中性反应液,经减压蒸馏得到无色液体即为产品1,1-二(叔丁基过氧化)环己烷,参考现有后处理工艺常规时间为1-2小时。现有后处理工艺耗时长,效率低,同时还需要单独设备如精馏塔等,不同过氧化羧酸酯、过氧化碳酸酯或过氧化缩酮后处理工艺也不同,现有生产工艺中也没有一种通用的设备和工艺能做到可以纯化各种不同过氧化羧酸酯、过氧化碳酸酯或过氧化缩酮。
因此,现有工艺生产得到符合市售标准的过氧化羧酸酯、过氧化碳酸酯或过氧化缩酮需要分成四步,第一步为氧化工艺,其产物为包含烷基过氧化物、杂质和大量的水的混合物;第二步为纯化工艺,除杂质和大量的水,制得符合市售工业品要求的烷基过氧化物(即中间产品),并将其存储备用;第三步为缩合工艺,制得目标产物(过氧化羧酸酯、过氧化碳酸酯或过氧化缩酮)粗品;第四步后处理工艺,除去杂质和水,制得符合市售工业品要求的过氧化羧酸酯、过氧化碳酸酯或过氧化缩酮。现有生产工艺中,在氧化工艺后必然累积一定量的烷基过氧化物,即宏观上存在中间产品的累积和存储;烷基过氧化物经过纯化后才用于下一步缩合工艺,即过程中存在中间产品纯化工艺和相关操作流程。这说明氧化工艺和缩合工艺实质上是两个相互独立工艺,因此,现有工艺制备过氧化羧酸酯、过氧化碳酸酯或过氧化缩酮从整体上来说都是间歇工艺。此外所述的烷基过氧化物属于易燃易爆危险品,因此该类化合物累积、存储和纯化等过程存在很大的安全风险,并且由于所述的烷基过氧化物易燃易爆对温度异常敏感,需要冷链储存和运输,这大大增加了使用和生产成本。现有技术存在烷基过氧化物的累积、存储和纯化,无法将氧化工艺和缩合工艺无缝衔接,实现从醇或烷烃全连续直接制备过氧化羧酸酯、过氧化碳酸酯和过氧化缩酮;同时由于现有工艺没有一种通用的后处理设备和工艺,无法将氧化、缩合工艺和后处理工艺结合在一起实现全连续,因此需要储存一定量的过氧化羧酸酯、过氧化碳酸酯或过氧化缩酮,而且所述的过氧化羧酸酯、过氧化碳酸酯或过氧化缩酮属于易燃易爆危险品,因此该类化合物存储和后处理等过程存在很大的安全风险,并且由于所述的过氧化羧酸酯、过氧化碳酸酯或过氧化缩酮易燃易爆对温度异常敏感,需要冷链储存和运输,这进一步增加了使用和生产成本。

间歇工艺最重要的特征有两点,一是过程中存在“停留”或“中断”,二是产品生产是间隔开的,即产品存在批次并且一个批次生产只能得到固定数量的产品。也就是,对于每一批次的生产,固定数量的原料按 照反应步骤的顺序进行反应,最终得到有限的固定数量的产品(产物);然后再投入固定数量的原料,按照同样的步骤进行下一批次的反应,制得有限的固定品。
间歇工艺实现的方式有两种:1)分别用多个反应器(例如,烧瓶、反应釜等)实现,每一步反应在一个反应器中进行;2)用一个反应器(例如,烧瓶、反应釜等)实现,在该反应器中依次完成每步反应,反应过程中需要根据反应进程依次添加多个原料,也就是每一步反应后,就会有“停留”,等待进一步添加后续反应的原料。有的文献也把方式2)称作连续(continuous),其实质也是间歇的,因为过程中存在“停留”,需等待加料,或者需要为下一步反应调节到合适的温度(例如,升温、降温或保温)。
间歇工艺主要存在以下问题:
1.间歇批次操作效率不高,反应时间很长,生产周期非常长,工艺过程中必然有氧化产物(即中间产品)烷基过氧化物的存在,而且还需要冷链储存和运输大量的氧化产物和最终产品,造成产品使用和生产成本长期居高不下。
2.第一步氧化工艺无论是使用氧气自氧化法,还是使用双氧水氧化法,间歇工艺反应器持液量大,单次反应需要大量纯氧或双氧水,因此间歇工艺存在很大的安全隐患。
3.第三步缩合工艺大都是放热反应,需要反应器具有很好的换热性能,保证反应不飞温。一旦温度过高,产品会发生分解,使收率降低。现有间歇工艺主要通过控制氧化剂的加入速度(缓慢滴加或缓慢通气)结合相应的移热装置来实现对反应温度的控制,这样一是大大延长了操作时间,降低了生产效率;二是由于大量过氧化物长时间存在,工艺安全隐患很大,并没有从根本上解决工艺安全性问题。即间歇工艺安全性、产品收率和质量稳定性都亟待改善。
4.间歇工艺不可避免地会带来放大效应(Scaling up Effect),给工业上生产规模放大带来很大障碍。
所述的放大效应是指利用小型设备进行化工过程(即小规模)实验(例如实验室规模)得出的研究结果,在相同的操作条件下与大型生产装置(例如工业化规模)得出的结果往往有很大差别。有关这些差别的影响称为放大效应。其原因主要是小规模的实验设备中的温度、浓度、物料停留时间分布与大规模设备中的不同。也就是说,相同的操作条件下,无法在工业化规模上完全重复小规模实验的研究结果;若要在工业化规模上得到与小规模实验相同或近似的结果,需要通过优化调整,改变工艺参数和操作条件。对于化工过程来说,放大效应是一个难度较大而且迫切需要解决的问题。如果不解决,会导致生产过程和产品质量具有很大的不确定性,一是直接导致下游产品的质量不稳定,难以控制;二是不确定性会带来生产过程工艺参数波动,进而导致无法有效控制生产过程,使得生产安全性不能得到保证,为生产过程埋下诸多安全隐患。
现地生产是指生产厂家将设备安置到终端消费者(或下游使用者)就近或同一地点进行生产,从而很大程度减少了从生产厂家到终端消费者(或下游使用者)之间的众多中间环节如仓储,物流等,节约了大量成本。但是现地生产仍无法避免少量产品的储存和运输,例如,从工厂的一个车间运送到另一个车间,从合成产品的生产设备取出产品并运送至下游的生产设备。在线生产(on-line manufacturing)作为现地生产的一种,是指产品的生产和使用同时进行,与下游工艺无缝衔接、同步联动的生产方式,从而实现产品的即产即用(produce-to-use)、随用随产(ready-to-use)的弹性生产模式(flexible manufacturing)。实现在线生产,需要借助于即插即产型生产装置(plug-and-produce system)。所谓即产即用,就是产出即使用,产品的生产和使用同时进行;随用随产,就是随时需要随时产出,无须等待,按需生产零库存;即插即产型生产装置,就是生产装置开动后即时获得产品,按需生产,满足需求后即可停车。在线生产的生产时间可以缩短至十余分钟甚至数分钟内,可以和下游使用者的生产设备和生产工艺实现无缝对接,从根本上避免了产品的储存和运输,节约了成本、提高了生产的安全性,也提高了生产效率。所述的生产时间是指从原料进入反应器到符合市售产品输出所需的时间,包括反应时间和后处理时间,在连续流工艺中也称其为停留时间(residence time)。在线生产作为一种高度灵活的生产方式,除了与其它现地生产方式一样可以节约大量仓储、物流等成本外,同时能有效地满足快速、个性化和定制化的产品需求,也符合工业化4.0和智能制造主导的第四次工业革命的发展方向。
本发明的有机过氧化物一体化全连续流工艺和反应器,可以直接无缝衔接到下游终端用户的工艺和反应器上,实现即产即用,甚至可能实现整个工艺过程中宏观上没有过氧化羧酸酯、过氧化碳酸酯或过氧化缩酮的累积和累积过程。一体化全连续流工艺可直接与高分子材料领域的聚合釜,胶片工业的硫化机等连接,形成有机过氧化物的生产和使用的全连续,颠覆现有生产-存储-运输-储存-使用生产模式,实现生产即使用的新型生产模式,有机过氧化物在线生产,即产即用,按需生产,零库存无物流。例如过氧化2-乙基己基碳酸叔丁酯作为交联剂,是目前太阳能组件中EVA胶膜最关键的核心原料,本发明的一体化连续流反应器可以与EVA膜硫化机无缝衔接,符合市售标准的过氧化2-乙基己基碳酸叔丁酯从一体化连续流反应器流出后,直接与硫化机的配料釜相连,随后进入硫化机真空层压得到EVA膜,最后裁剪包装。真正做到生产就是使用,没有过氧化2-乙基己基碳酸叔丁酯的累积和储存,一方面大大提高了整体工艺的安全 性,另一方面进一步降低了生产成本,大幅度提高了生产效率。
有机过氧化物是非常活泼的化合物,极易分解为高反应活性的自由基和氧,该过程中会释放大量的热甚至引发爆炸,因此有机过氧化物对温度异常敏感,必须低温储存和运输。现有工艺过程存在大量氧化反应产品(烷基过氧化物)和产品(过氧化羧酸酯、过氧化碳酸酯或过氧化缩酮)的累积、纯化、存储和运输,两者均为易燃易爆的有机过氧化物,因此现有有机过氧化物生产成本的1/3用于中间产品和产品的冷链储存和运输。而在线生产是在需要使用产品时按需进行生产,即产即用、随用随产,实现产品零库存、无运输,这将大大降低有机过氧化物生产和使用中的库存和物流成本,同时也将其中的安全风险降到了最低。但现有工艺尚无法实现从醇或烷烃直接生产过氧化羧酸酯、过氧化碳酸酯或过氧化缩酮连续流工艺以及与之匹配适用的即插即产型反应器,因此无法做到上述有机过氧化物的真正意义上的在线生产,也就无法从根本上解决有机过氧化物的生产和使用中巨大的安全风险并降低生产和使用成本。
中国专利CN101479239描述了使用具有高热交换能力的板式换热器来连续制备有机过氧化物的方法,通过在板式换热器不同位置(板块)引入不同的反应物,在给定的温度下连续制备选定的过氧化物。其温度给定值为这样的温度,即高于该温度时有机过氧化物变得热敏感。这表明其反应温度给定值均低于相应有机过氧化物SDAT,最终优选的反应温度范围为5~60℃。相比较间歇工艺,产率接近虽温度更高,不过要低于相应有机过氧化物SADT。合成反应时间在实验室规模为1秒到45秒的范围内,而在工业规模上最高达2分钟到3分钟。所述反应时间是指反应物料进入反应器中到反应结束得到目标产品粗品所需的时间,不包括后处理的时间。相比间歇工艺,该连续制备方法在生产效率和安全性上有一定的优势,但是由于不可避免地存在了放大效应,其工业规模反应时间是实验室规模的2~180倍,存在大幅度不确定(反应时间2~180倍极宽范围的延长)的放大效应,大大增加了工业化的难度。这种大幅度不确定的放大效应会给该工艺的工业化应用带来诸多不利,例如,在向工业化放大时,只能采取多次逐级放大的方法,并且为了获得与实验室规模一致性的结果,每次放大过程都要重新调整优化工艺条件和参数,这会极大地消耗人力物力和项目开发的时间;即使采用多次逐级放大,由于放大效应变化幅度太大,也可能最终导致放大后无法达到实验室规模的好结果;同时大幅度不确定的放大效应会影响工艺的稳定性和可靠性,导致产品质量不稳定,难以控制;另外,这也会给生产过程带来潜在的安全风险。同时,该专利仅报道醇或烷烃生产烷基过氧化物的连续工艺或烷基过氧化物生产过氧酯的连续工艺,但不能实现以醇或烷烃为起始原料全连续直接生产过氧化羧酸酯、过氧化碳酸酯和过氧化缩酮。
中国专利CN102617432描述了以叔丁醇为原料生产过氧化2-乙基己基碳酸叔丁酯的方法,但该专利存在的问题如下:
一是生产工艺中在相当一段时间内仍存在大量氧化产物叔丁基过氧化氢累积、纯化和停留等待等流程,正如上面所说这带来了很大的安全隐患,并且为保证生产安全,这些过程中需要维持低温,大大增加了生产成本;
二是从叔丁醇到生产过氧化2-乙基己基碳酸叔丁酯的整个过程都是间歇工艺,在工业放大时必然会存在放大效应,极大地增加了工业放大的难度;
三是生产时间需要3~18小时,反应时间长,生产效率低,不可能实现在线生产,即产即用。
综上,有机过氧化物现有生产工艺中存在诸多问题:相当一段时间内仍存在有机过氧化物(包括氧化反应产品和产品)的累积、纯化、存储和运输过程;使得工艺存在极大的安全隐患;尚无法实现从醇或烷烃直接生产过氧化羧酸酯、过氧化碳酸酯或过氧化缩酮全连续流工艺以及与之匹配适用的即插即产型反应器,因此无法做到上述有机过氧化物的真正意义上的在线生产,这些都造成其无法从根本上解决有机过氧化物的生产和使用中巨大的安全风险并降低生产和使用成本。此外,现有工艺均存在不同程度的放大效应,导致向工业化放大时会消耗大量人力物力且存在诸多不确定性;放大后工艺可靠性也存在问题,导致产品质量不稳定,难以控制;并且生产过程缺乏灵活性并且会有潜在的安全风险;由于反应温度低,导致反应总时间过长且产率不高,降低了生产效率,这些都增加了工业化的难度。而无法实现大规模生产,就限制了其应用。因此,需要寻找一种操作简单安全,高效,能够在线生产,易于大规模生产且无放大效应的有机过氧化物的全连续流生产工艺。

本文所用术语“环烷基”是指具有3到12个碳原子的饱和单环碳环,除非指明不同数目的原子。环烷基包括环丙基、环丁基、环戊基、环己基、环庚基和环辛基等。环烷基可以是无取代或取代的。环烷基还可任选在任何可利用碳上被一个或多个选自烷氧基、卤素、卤代烷基如全氟烷基等取代基取代。
本专利所用术语“烷基”包括直链烷基和支链烷基。如提及单个烷基如“丙基”,则只特指直链烷基,如提及单个支链烷基如“异丙基”,则只特指支链烷基。例如,“C1-6烷基”包括C1-4烷基、C1-3烷基、甲基、乙基、正丙基、异丙基和叔丁基。

连续生产工艺(连续工艺,continuous process)是指生产过程中生产系统各生产步骤之间相互衔接,整体上保证持续运行,但每个步骤中允许停留等待。连续流生产工艺(连续流工艺,continuous-flowprocess)作为连续工艺的一种,是一种快速高效的全流程连续工艺,具有用时短、效率高、易操作等特点,过程中连续不间断地加入原料,连续不间断地生产制得产品,过程中物料(即包含有原料、中间体、产品、溶剂等的反应混合物)是连续流动的,没有间断,没有停留等待,即产品被源源不断地生产出来,是一种“流水线”式的化工生产过程。当工艺操作达到定态时,反应器内任何位置上物料的组成、温度等状态参数不随时间而变化,是稳态过程,因而生产过程和产品质量都是稳定的。在包含有多步反应的工艺中,如果其中某几个步骤是连续的或者只是将原有间歇工艺中的各步骤简单连接起来,该工艺可以称为半连续工艺;而只有所有步骤都是连续的并且物料在整个工艺过程中是连续流动的,即连续加入原料,连续得出产品,才能称为连续流工艺(或者全流程连续工艺)。现有技术生产过氧化羧酸酯、过氧化碳酸酯、过氧化缩酮等有机过氧化物的工艺,氧化反应和缩合反应是分别进行的,从整个工艺过程来说,氧化和缩合是两个分别进行的步骤,因此是间歇工艺。
为解决本发明的技术问题,本发明创新性地提供一种由醇或烷烃直接制备有机过氧化物的在线全连续流生产工艺,所述的生产工艺以非常安全的物料醇或烷烃为起始反应原料,连续依次经氧化缩合和后处理两个过程制得有机过氧化物,所述的生产工艺在即插即产型一体化连续流反应器中进行,在所述一体化连续流反应器的进料口不间断加入反应底物、氧化剂和缩合剂,在所述一体化连续流反应器出料口不间断得到目标产品有机过氧化物,所述的生产工艺无放大效应,所述的有机过氧化物选自过氧化羧酸酯、过氧化碳酸酯、过氧化缩酮,所述的反应底物为醇或烷烃,所述缩合剂在生产过氧化羧酸酯、过氧化碳酸酯时为碱液和酰基化合物,在生产过氧化缩酮时为酸液和缩合原料,所述缩合原料为醇或酮。
本发明通过集成反应工艺和即插即产型一体化连续流反应器的优势,彻底改进了现有技术生产有机过氧化物的工艺,能够实现有机过氧化物的在线全连续流生产,将氧化缩合过程与后处理过程有效地整合为一个工艺,不仅实现了从安全的起始物(醇或烷烃)直接生产危险程度高的有机过氧化物,宏观上没有危险的烷基过氧化物(中间产品)的累积、纯化和停留等待的过程,避免了烷基过氧化物的纯化、储存和运输步骤,实现了有机过氧化物的即产即用,而且还克服了放大效应问题,同时实现了在线生产(on-line manufacturing),产品的生产和使用同时进行,与下游工艺和设备无缝衔接、同步联动的生产方式,从而实现产品的即产即用(produce-to-use)、随用随产(ready-to-use)的弹性生产模式(flexible manufacturing)。也就是随时需要随时产出,无须等待,按需生产零库存,按需生产,满足需求后即可停车。不仅保证了有机过氧化物的优质高效生产,还能与与下游工艺无缝衔接、同步联动,进而可以避免目标产品有机过氧化物的储存和运输步骤,从根本上解决了烷基过氧化物和最终产品(过氧化羧酸酯、过氧化碳酸酯、过氧化缩酮)冷链仓储和运输的成本及安全性问题。

本发明与现有技术的比较,有益效果如下:
1.本发明通过集成反应工艺和即插即产型一体化连续流反应器的优势,彻底改进了现有技术生产有机过氧化物的工艺,首次实现了从安全的起始物(醇或烷烃)直接生产危险程度高的有机过氧化物,宏观上没有危险的烷基过氧化物(中间产品)的累积、纯化和停留等待的过程,避免了烷基过氧化物的纯化、储存和运输步骤,实现了有机过氧化物的即产即用,同时实现了在线生产(on-line manufacturing),产品的生产和使用同时进行,与下游工艺和设备无缝衔接、同步联动的生产方式,从而实现产品的即产即用(produce-to-use)、随用随产(ready-to-use)的弹性生产模式(flexible manufacturing)。也就是随时需要随时产出,无须等待,按需生产零库存,按需生产,满足需求后即可停车。不仅保证了有机过氧化物的优质高效生产,还能与与下游工艺无缝衔接、同步联动,进而可以避免目标产品有机过氧化物的储存和运输步骤,从根本上解决了烷基过氧化物和最终产品(过氧化羧酸酯、过氧化碳酸酯、过氧化缩酮)冷链仓储和运输的成本及安全性问题。
2.本发明的生产工艺完全不同于现有技术的工艺,仅通过一步反应,并且将反应过程与后处理工艺整合成为一套完整的生产工艺,在短时间内(15分钟内)直接制得符合市售市售工业品标准的产品,实现了高质量、高效率的生产。
3.本发明的生产工艺通用性强,通过将反应工艺与反应器进行有机的整合,打破了不同有机过氧化物的生产工艺无法通用的现有缺陷,通过调整不同的工艺参数和反应器参数,可以在同一台即插即产型一体化连续流反应器上实现不同种有机过氧化物的生产,满足了用户的多种需求,提高了生产效率。
4.本发明的生产工艺安全、高效,制得的有机过氧化物产品产率和含量高,大幅度降低生产成本、提高有机过氧化物生产和下游产品生产的安全性,实现了有机过氧化物的高效率、高质量、大规模生产。
5.本发明解决了有机过氧化物连续流工艺工业化放大的问题,本发明的生产工艺不存在放大效应,极大地降低了工业化应用的难度,在向工业化放大时,无需经历繁琐复杂的多次逐级放大和工艺条件、参数的调整优化,即可一次放大到所需要的生产规模,极大地节约了人力物力和项目开发时间。
6.本发明的生产工艺安全性得到了极大提升,连续流反应器相对较小的持液量和优良的传热特性,加之较短的反应时间(15分钟以内)使得该工艺过程更为安全。其中所述的反应器持液量是指当操作达到定态时,任一时刻反应器中存有的反应物料的总体积。
7.相比于现有技术,本发明的反应时间大大缩短,反应时间缩短了95%,大幅度提高了反应效率。
8.在一体化连续流反应器中,由于流速稳定、生产过程稳定,因而产品质量稳定、重现性好。
9.该一体化连续流反应器体积小,占地面积小,极大地节约了厂房用地。
