性质描述:

无色至黄色固体。熔点36.5℃，沸点115-118℃（1.33×10-4kPa）。溶于水、丙酮、苯、乙醇、环已烷、甲苯，微溶于乙醚，难溶于已烷。在中性和弱酸条件下，硫环磷水溶液稳定，但碱性（pH＞9）或酸性（pH＜2）的条件下水解。

生产方法:

2-亚氨基-1,3-二硫戊环盐酸盐与O,O-二乙基硫代磷酰氯在苯-水混合溶剂中搅拌，在约半小时内加入乙酸钠水溶液，搅拌后静置分层，分离苯层，水层用乙醚萃取一次，合并苯-醚层，用稀碳酸钠溶液和水洗涤，干燥，用石油醚洗，结晶，得产品。原料消耗定额：2-亚氨基-1,3-二硫戊环盐酸盐1080kg/t、O，O-二乙基硫代磷酰氯1300kg/t。

用途:

内吸性杀虫性，用于防治刺吸式口器害虫，螨和鳞翅目幼虫。该药剂在土壤、植物和动物体内无持效性，在N-P键处代谢，变成无毒的可溶于水的化合物。
