精恶唑禾草灵制备
苯硫威可通过1,4-二氯丁烷合成。
(1)1,4-二氯丁烷的制备 四氢呋喃40g、氯化锌52g在搅拌下滴加36%盐酸222.4g,于50℃滴入,然后升温至90~105℃,反应15h,在反应过程中通入氯化氢气体,使反应液保持酸性,经后处理得1,4-二氯丁烷,收率85.2%。
(2)4-氯丁基苯醚的制备 苯酚13.5g和1,4-二氯丁烷54.5g搅拌加热至100℃,滴入48%氢氧化钾水溶液24.5g,约30min滴毕,于100℃继续反应3h,经后处理并回收1,4-二氯丁烷。产物收率71.6% (以苯酚计)。
(4)N,N-二甲基硫代氨基甲酸钠的制备 将10g氢氧化钠溶于31g水中,冷却至5℃,加入30%二甲胺水溶液7.5g,于0~5℃通扩氧硫化碳气体,至增重15g,制得N,N-二甲基硫代氨基甲酸钠溶液,含量约34%,待用。
(4)苯硫威的合成 4-氯丁基苯醚9.2g和四丁基溴化铵0.2g,搅拌加热至60℃,将约34%N,N-二甲基硫代氨基甲酸钠溶液22.5g加入,于60℃反应4h,经后处理得苯硫威,收率85%。据文献报道此步收率可达98.7%。
苯硫威也可通过下述方法合成:
