性质描述: 无色或琥珀色液体。沸点68℃(1.6kPa),相对密度1.32(20/5℃),折光率1.4795(25℃)。溶于乙醇、苯、氯仿、四氯化碳、乙醚、乙酸乙酯等有机溶剂,微溶于己烷,不溶于水。
生产方法: 由甲醇与三氯硫磷反应生成O-甲基硫代磷酰氯,然后再与甲醇进一步反应而得。将173kg三氯硫磷投入反应锅中,搅拌冷却至-15℃,缓缓加入甲醇,温度控制在-5℃左右,加完161.5kg甲醇后,再搅拌反应10min。将反应物放在0℃的冷水中洗涤、分层,下层为O-甲基硫代磷酰氯(即二氯化物)。按二氯化物量的1.08倍称取固体氢氧化钠,溶解在4倍的重量的甲醇中配成醇碱液。将其冷至-15℃,滴加入二氯化物中,控制温度在-5℃左右。加毕,将料液吸入水洗锅中,加1%的盐酸水洗涤,静置分层,下层即为O,O-二甲基硫代磷酰氯。
用途: 该品为农药中间体,可用于生产杀暝松、杀暝晴、1605、甲基1605、甲胺磷和乙酰甲胺磷等。该品具有有机磷农药的毒性,对眼、粘膜及皮肤有刺激性,吸入或经皮肤吸收会引起中毒。小白鼠口服LD50为450mg/kg。
