补充资料:杀虫环
分子式:C7H13NO4S3
分子量:271.26
CAS号:31895-22-4
性质:无色无臭结晶。熔点125-128℃(分解),20℃的蒸气压为5.3×10-2Pa。23℃水中溶解度为84g/L,丙酮500mg/L,乙醇1.9g/L,甲醇17g/L,二甲苯<10g/L,不溶于煤油。在22-24℃缓冲溶液中分解50%(40ml/L)的时间:pH=5时为42d,pH=7-9时为11d。避光50℃放置四星期不降解。
制备方法:由氯丙烯为起始原料,经胺化、氯化制得3-N,N-二甲氨基-1,2-二氨丙烷二氯丙烷,其盐酸盐和硫代硫酸钠反应制得2-N,N-二甲氨基-1-硫代硫酸基-3-硫代硫酸钠基丙烷(简称单钠盐),再与硫化钠环化、成盐而得。
用途:选择性杀虫剂。具有胃毒、触杀、内吸作用。防治鳞片目和鞘翅目害虫的持效期为7-14d,也可防治寄生线虫,如水稻白尖线虫,对一些作物的锈病和白穗病也有一定的防效。
