摘　　要：在惰性溶剂介质中,以一般化学品固体光气和十八烷基伯胺为主要原料,采用一步法反应合成十八烷基异氰酸酯。进行了惰性溶剂的筛选,同时考察了物料的配比、反应温度、反应时长对反应的影响。结果表明,以甲苯作为惰性溶剂,十八烷基伯胺和固体光气的摩尔比为1∶0.40,保温反应温度在100℃持续反应1.5 h,在此条件下十八烷基异氰酸酯的产率为94.98%。The synthesis of octadecyl isocyanate ODI with octadecylamine(ODA)and triphosgene(BTC)by one-step method was studied.Selection on inert solvent,factors such as molar ratio of raw materials,reaction temperature and reaction time were also studied.The optimal conditions were determined as follows:the molar ratio to ODA and BTC 1∶0.40,the reaction 1.5 h,the reaction temperature 100℃.Under the optimum condition,the ODI yield was 94.98%.
