性质描述: 浅黄色油状体。熔点2.85(-7℃),沸点156-157℃(93Pa),30℃时的蒸气压为0.53×10-2Pa,相对密度为1.2315(25/4℃),折光率为1.4985(25℃)。溶于乙醇、丙酮、苯、石油、植物油、氯仿、甲氯化碳。在水中的溶解度仅为0.0145%。对光稳定,对热稳定性差。在中性介质中稳定;在碱性介质中水解成硫化物钠盐和反丁烯二酸二乙酯;在酸性介质中水解成硫化物和α-硫醇基琥珀酸二乙酯。
生产方法: 由五硫化二磷和甲醇合成二甲基二硫代磷酸酯,然后与顺丁烯二酸二乙酯加成得到马拉硫磷。将顺丁烯二酸二乙酯(以100%计为380kg)投入1000L搪玻璃反应锅内搅拌,控制温度在45℃以下,投入350kg五硫化二磷。慢慢滴加甲醇,控制温度为48-55℃,约2h加完250kg甲醇。加毕,保持65-75℃反应8h。反应产生硫化氢和逸出甲醇蒸气,经冷凝器使甲醇回流,硫化氢则用碱液吸收。反这过程在负压下进行。反应完成后,冷却至40-50℃,静置分层使杂质沉淀。上层原油先后进行水洗、碱洗、水洗,然后在真空脱水锅进行脱水,在85℃以下(真空度93.3kPa)使原油中的水分蒸发1.5-2h,得马拉硫磷原油。原料消耗定额:顺酐430kg/t、五硫化二磷470kg/t、乙醇420kg/t、甲醇390kg/t。
用途: 马拉硫磷是高效低毒杀虫、杀螨剂,防治范围广。不仅用于稻、麦、棉,而且因毒性低、残效短,也用于蔬菜、果树、茶叶,以及仓库的防虫。主要防治稻飞虱、稻叶蝉、棉蚜、棉红蜘蛛、麦粘虫、豌豆象、大豆食心虫、果树红蜘蛛、蚜虫、粉蚧壳虫、巢蛾、蔬菜黄条跳、菜叶虫、茶树上的多种蚧类,以及蚊、蝇幼虫和臭虫等。
