Description
技术领域
本发明涉及一种化工中间体的制备方法,具体地,涉及一种芳酰胺类化合物的制备方法。
背景技术
酰胺类化合物是一类重要的化合物,在医药、生物、材料等方面有着广泛的应用。而苯甲酰胺经常被作为除草剂、杀菌剂、分散剂、抗精神病药物和扩血管药物。因此高效、低成本的合成酰胺类化合物是非常有意义的工作。目前酰胺的合成普遍存在使用有毒溶剂、贵金属、剧毒氯化试剂,并且操作复杂需要再无水条件下进行,后处理繁琐等不足,不适合大规模应哟领生产。芳酰胺一类重要的化工中间体,是多种化工产品的重要中间体。合成该类化合物的方法有很多,如下列反应式(1)、(2)、(3)所示:
但这些方法都存在很多不足,不能满足大规模、低成本、低污染的生产需求。
经检索发现公开号为WO2012123328、WO2012014760的国际PCT专利和文献Chemistry-An Asian Journal,2015,2631-2650等文献,利用酯在催化剂的作用下,在溶剂中与氨气、氨水在高温高压下合成酰胺的合成方法。这类反应条件苛刻,能耗高,设备要求高,生产成本高。
文献Journal of the American Chemical Society,2013,16853-16864报道了酰氯与氯化铵在溶剂中,在碱性条件下低温合成酰胺的方法。该方法的酰氯制备和后处理会带来大量的废水,对环境的压力很大。
文献Journal of Organic Chemistry,1987,2662-5报道了在低温下,酰氯与氨气的氨化反应。该方法同样面临酰氯的制备与后期处理的“三废”问题。
文献ACS Catalysis,2017,5862-5870报道了酰氯与氨水的氨化反应。这类方法普遍存在酰氯的制备与后期处理带来大量废水,且操作复杂,生产成本高的不足。
经检索,公开号为CN 10945621的中国专利和文献Green Chemistry,2019,4329-4333提出了酸和氨气在相转移催化剂作用下合成酰胺的方法。但由于使用了昂贵的相转移催化剂,并不适合大规模生产。此外还有用偶联试剂来合成酰胺,也同样面临成本的不足。
因此开发新的生产工艺取代传统的生产工艺,在降低成本的同时减少三废对环境的污染是绿色化学必须面临和解决的问题。
