性质描述: 白色结晶粉末。熔点40-42℃,沸点152-154℃,97℃(1.33×10-3kPa),相对密度1.4575(50/4℃),折光率1.5530(50℃)。25℃的蒸气压1.1×10-4kPa。易溶于于丙酮,四氯化碳,乙醚,氯仿等,难溶于水。在中性和酸性介质中稳定,但在碱性介质中易水解失去杀虫活性。
生产方法: 由 2,4,5-三氯苯酚与O,O-二甲基硫代磷酰氯缩合而得。将2,4,5-三氯苯酚,25%氢氧化钠加入反应锅内,搅拌,加热至50-60℃,使其全部溶解。冷至45℃,滴加O,O,-二甲基硫代磷酰氯,滴完后在45℃搅拌10min。升温至65℃,维持20min。冷至40℃,加入10%氢氧化钠溶液。继续冷却,析出皮蝇硫磷结晶,在13.5-14.5℃时过滤。依次用水,0.75%(体积)盐酸溶液,水洗涤,得粗品。用乙醇重结晶,得白色成品,收率约95%。
用途: 皮蝇硫磷对多种害虫有很好的杀虫效果,兼具动物内吸和熏蒸作用。一般在驱虫上主要是利用动物内吸。由于蒸气压高,因此本品对卫生害虫,如家蝇很效,可以放在开口的容器内保存12-16周有效。同时因毒性低,可用于食品加工厂灭蝇,此外,使用本品熏蒸可有效防治粮食害虫。对农业害虫如麦杆蝇,防治效果与敌百虫相似,对小菜蛾的防治交果可达94.5%。
