性质描述: 该品有反式异构体[298-01-1]和顺式异构体[338-45-4]。顺式熔点6.9℃,相对密度1.245,折光率1.4524。反式熔点21℃,相对密度1.2345,折光率1.4452。速灭磷为两者混合物,其中反式含量60%。为淡黄色液体,沸点99-103℃(40Pa),折光率1.4494。蒸气压(20℃)为1.65×10-2Pa。易溶于水,能与醇、酮等多种溶剂混溶,微溶于酯肪烃。常温下贮存稳定,在水溶中水解。在碱性水溶液中水解加快,pH为6时半衰期为120d,pH为9时半衰期为3d,pH为11时半衰期只有1.4h。
生产方法: 由乙酰乙酸甲酯用硫酰氯进行氯化制得2-氯乙酰乙酸甲酯,进而与亚磷酸三甲酯反应,在甲苯中重排而得速灭磷(商品为40%乳油)。
用途: 速灭磷是水溶性触杀兼内吸的有机磷杀虫杀螨剂。杀虫谱广,对棉蚜、锦铃虫、苹果蚜、苹果红蜘蛛、玉米蚜、大豆蚜、菜青虫有较好的防效。
