本发明涉及的是一种工业有机化学品技术领域的制备方法,具体是一种饱和多氯代烷烃的制备方法。
背景技术
1,1,1,3,3-五氯丙烷(简称1,1,1,3,3-五氯丙烷)是制备氢氟烷烃1,1,1,3,3-五氟丙烷(简称HFC-245fa)的原料。HFC-245fa具有与一氟二氯乙烷(简称HCFC-141b)和一氟三氯甲烷(简称CFC-11)十分相似的物理性质,而且HFC-245fa的ODP值(大气臭氧消耗潜能值)为零,对大气臭氧层没有潜在的破坏作用,因此HFC-245fa被认为是CFC-141b和CFC-11的理想替代品,可以广泛应用于溶剂、清洗、发泡、制冷、气体推进剂等领域,是一种新型的环保产品。开发制备1,1,1,3,3-五氯丙烷(1,1,1,3,3-五氯丙烷)工业化生产工艺对制备高附加值HFC-245fa具有重要的经济价值。
现有技术中用于制备HFC-245fa的原料1,1,1,3,3-五氯丙烷的技术中已有多种方法,主要制备方法有以下几种:
经过对现有技术的检索发现,公开号WO9805614A1记载了一种“通过光氯化由1,1,1,3-四氯丙烷制备1,1,1,3,3-五氯丙烷的方法”,该方法以1,1,1,3-四氯丙烷为原料,与氯气在紫外光催化下合成1,1,1,3,3-五氯丙烷。该工艺经光催化氯化反应生成1,1,1,3,3-五氯丙烷的转化率不高,选择性差,工业放大较为困难。
又经检索发现,公开号WO9737956A1记载了一种“制备含有末端碳的卤化丙烷的方法”,该方法由1,1-二氯乙烯为原料,与四氯化碳调剂合成1,1,1,3,3,3-六氯丙烷,在还原成1,1,1,3,3-五氯丙烷。由于1,1-二氯乙烯是一种极易发生自聚的化学物质,对储存和运输及合成反应要求极高,不利于工业放大。
再经检索发现,公开号WO9601797A1记载了一种“制备1,1,1,3,3-五氯丙烷的方法”,该方法以氯乙烯为原料,与四氯化碳在铜盐作催化剂及胺类为助催化剂下调剂合成1,1,1,3,3-五氯丙烷。该工艺需要在特制的高压反应釜中完成,而且由于催化剂铜盐及助催化剂胺类的使用,使得反应后处理复杂。
