性质描述:

无色油状液体。熔点-45--48℃，沸点162℃（0.2kPa），相对密度1.2132（25/4℃），折光率1.4718（25℃）。20℃时的挥发度为0.41mg/m3，30℃为1.33mg/m3。易溶于水、醇、丙酮、乙醚、二氯甲烷，微溶于芳香烃，不溶于石油醚及脂肪烃。磷胺水溶液不太稳定，在中性及酸性中缓慢水解，在碱性高温下迅速水解。工业品含顺式异构体70%，反式异构体占30%，顺式异构体具有较强活性。

生产方法:

将二乙胺投入反应锅，搅拌，于40-45℃滴加双乙烯酮，加毕，反应1h，得二乙基乙酰基乙酰胺。将二乙基乙酰基乙酰胺加入氯化锅，在40-50℃通入氯气反应至氯化液丁对密度达到1.208-1.210，即为通氯络点。用3-5%氢氧化钠溶液洗涤氯化物，直至pH=6，减压脱水，控制水分在0.02%，即得氯化物。然后，将氯化物加热至85-95℃，加入亚磷酸三甲酯（摩尔配比为氯化物：亚磷酸三甲酯=1：1.07）。加毕，保温回流5h即缩合得到磷胺原油。

用途:

磷胺为广谱性有机磷杀虫剂，可防治刺吸式口器和咀嚼式口器的多种害虫。对棉蚜、棉红蜘蛛等棉花害虫有较高防效，对稻飞虱、稻叶蝉、月稻螟虫等也有优良杀伤效果。还用于防治甘蔗螟虫、大豆食心虫、梨小食心虫等。
