除虫脲分子式：C14H9ClF2N2O2分子量：310.68CAS号：35367-38-5性质：除虫脲纯品为白色结晶，熔点230-232℃。原药(有效成分含量95%)外观为白色至浅黄色结晶粉末，比重1.56，熔点210-230℃。20℃时在水中溶解度为0.1mg/L，丙酮中6.5g/L，易溶于极性溶剂如乙腈、二甲基砜，也可溶于一般极性溶剂如乙酸乙酯、二氯甲烷、乙醇。制剂由25%除虫脲及湿润剂、分散剂、惰性填料组成。外观为白色至浅黄色粉末，比重约0.4，悬浮率不低于60%，常温贮存稳定性最少2年。制备方法：将2,6-二氟苯甲酰胺和4-氯苯基异氰酸酯置于二甲苯中加热回流，反应完成后冷却，所得结晶物用二甲苯洗涤、干燥而得伏虫脲。用途：伏虫脲是一种新杀虫剂，对许多重要害虫的幼虫具有胃毒作用。它通过干扰表皮沉积作用，使昆虫不能正常蜕皮或变态而死亡。也可抑制昆虫卵内胚胎发育过程中的表皮形成，使卵不能正常发育孵化，同时对昆虫的生殖力也有一定的抑制作用。该品杀虫谱广，特别是对鳞翅目幼虫的效果尤为明显。由于其特有的作用机制，对人畜低毒，对天敌危害性小，是近年来发展的比较好的选择性杀虫剂。
