- 用途三:有机合成中间体,用于杀菌剂苯莱特的生产。
- 方法二:由正丁胺与光气作用而得。将正丁胺、邻二氯苯加入反应器中,在搅拌下通干燥的氯化氢气体直至饱和,然后在110-160℃通入过量光气,至溶液变清后再通入20-30min,通毕,蒸馏,收集160℃以前馏分,再经蒸馏,收集106-120℃馏分,加入无水碳酸钾静置,过滤而得成品。此外,由溴丁烷与氰酸钾在有机溶剂(二甲基甲酰胺)中作用,亦可制得。
- F:10-19-21
- 用途二:正丁基异氰酸酯是杀菌剂苯菌灵的中间体,用光气法制备磺酰脲类除草剂时需用正丁基异氰酸酯作为催化剂,使反应平稳和收率高。
- 方法一:其制备方法是在反应釜中投入计算量的二甲苯、正丁胺,在常温下滴加浓盐酸,滴加1h,然后回流分水约8h,温度升至140℃成盐完毕,稍降温开始通光气,回流反应,通完光气维持回流反应2h,然后通氮气,排除过量光气,并降至室温,将料液精馏收集114~116℃馏分即得产品。
