Aliphatic isocyanates are manufactured by thermal decomposition of aliphatic carbamic acid halides, an inert gas being passed in during the decomposition and being removed together with the hydrogen halide formed. The isocyanates which may be manufactured by the process of the invention, particularly ethyl isocyanate, n-propyl isocyanate and isopropyl isocyanate, are valuable starting materials for the manufacture of plant protection agents, pesticides, dyes, synthetic resins, plastics, hydrophobic agents for textiles, detergents, bleaches and adhesives.
脂肪族异氰酸酯是通过烷基羰酸卤化物的热分解制造的,分解过程中通过惰性气体,同时将生成的氢卤酸一起移除。可以通过本发明的方法制造的异氰酸酯,特别是乙基异氰酸酯、正丙基异氰酸酯和异丙基异氰酸酯,是制造植物保护剂、杀虫剂、染料、合成树脂、塑料、纺织品疏水剂、洗涤剂、漂白剂和粘合剂的宝贵起始原料。
