环己胺制备方法及用途

制备方法

1.由苯胺催化加氢而得，可分为常压法和加压法。此外，通过环己烷或环己醇的催化氨解，硝基环己烷还原，以及氢存在下的环己酮催化氨解等方法均可制得环己胺。精制方法：常含有苯胺和水等杂质。精制时首先将环己胺转变为盐酸盐，用水重结晶，精制后在碱性溶液中用乙醚萃取，固体氢氧化钾干燥，在氮气流中蒸馏。在4.65KPa的压力下精馏，可将苯胺除去。 2.以镍或钴为催化剂，在高温、高压下由苯胺进行催化还原得到。也可由苯酚催化还原得到环己醇，氧化为环己酮，再与氨进行氨基化而得到环己胺。

用途简介

本品用以制备环己醇、己内酰胺、醋酸纤维和尼龙6等。环己胺本身为溶剂，可在树脂、涂料、脂肪、石蜡油类中应用。也可用于制取脱硫剂、橡胶抗氧剂、硫化促进剂、塑料及纺织品化学助剂、锅炉给水处理剂、金属缓蚀剂、乳化剂、防腐剂、抗静电剂、胶乳凝固剂、石油添加剂、杀菌剂、杀虫剂及染料中间体。环己胺的磺酸盐，作为人工甘味料，用于食品、饮料和医药。也用作酸性气体吸收剂。用作锅炉给水ph值调节剂。环己胺属于挥发性物质，加药后很容易到达整个系统。若ph低于 5，对环己胺处理效果不利。是合成脱硫剂、橡胶促进剂、染料、抗静电剂、缓蚀剂、农药杀菌剂、杀虫剂等的中间体。用作锅炉水处理剂及腐蚀抑制剂，橡胶促进剂，有机合成中间体。
