性质描述: 白色结晶。熔点36-36.5℃,沸点154℃(0.133kPa),相对密度1.358(20/4℃),折光率1.5367(25℃),蒸气压(20℃)0.13×10-2Pa,在水中的溶解度为50ppm,能溶于多种有机溶剂。在中性和弱酸性介质中较稳定,在碱性介质中很快水解,在130-140℃下迅速异构化。
生产方法: 由O,O-二甲基硫化磷酰氯在溶剂中与对硝基苯酚缩合而得。将二甲苯和对硝基酚钠在96℃(73.3-76.0kPa)以下共沸脱水2-3h,加入碳酸钠和铜粉,升温至90℃左右,滴加O,O-二甲基硫代磷酰氯。加毕,搅拌保温2-3h。冷却至50℃,过滤,用少量二甲苯冲洗滤渣,滤液用5%碳酸钠溶液洗至无色,再用饱和食盐水洗至中性,分出油层,减压蒸出二甲苯,即得甲基对硫磷原油。原药为浅黄色至浅棕色液体或固体。原料消耗定额:黄磷210kg/t、氯气690kg/t、硫黄200kg/t、甲醇600kg/t、对硝基酚钠730kg/t。
用途: 该品为有机磷杀虫剂,具触杀和胃毒作用,能抑制害虫神经系统中胆碱酯酶的活力而使其致死,杀虫谱广,常加工成乳油或粉剂使用,防治对象与对硫磷(一六○五)相似,能防治水稻、棉花、果树、茶叶、蔬菜等作物的多种害虫。但防治效果稍低于对硫磷,因此用量要增加。由于甲基对硫磷比对硫磷安全,常用于防治棉花、果树的害虫。
