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：
