中文名称:茂果;O,O-二甲基-S-(N-吗啉基甲酰甲基)一硫代磷酸酯

英文名称:phosphorodithioic acid, o,o-dimethyl ester, s-ester with 4-(mercaptoacetyl)morp;holine;4-(mercaptoacetyl)morpholine o,o-dimethyl phosphorodithioate;dimethyl s-(morpholinocarbonylmethyl) phosphorothiolothionate;dithiophosphate de o,o-dimethyle et de s-((morpholinocarbonyle)-methyle);ekatin f

性状描述:外观为白色晶体。熔点63-64℃。水中溶解度为0.5%,能溶解于多数有机溶剂。

生产方法:以氯乙酰吗啉与O,O-二甲基二硫代磷酸钠直接缩合而得。工艺条件:配料比为O,O-二甲基二硫代磷酸钠:氯乙酰吗啉=1.05-1.10(摩尔比)。将O,O-二甲基二硫代磷酸钠加入反应瓶,冰浴冷却,当料温下降至-8℃以下时,再加吗啉(30%以上),保持温度在-5℃以下。滴加氯乙酰氯,待pH值接近7时,迅即滴加液碱。氯乙酰氯滴完后,于-8℃搅拌反应1h。然后加苯,于50-60℃搅拌反应1h,降温;静置,分出苯层,减压蒸馏而得茂果。配制成25%乳剂或粉剂。

用途:茂果具有内吸性强、高效、低毒等特点,主要用于防治棉蚜、菜蚜、棉红蜘蛛,棉蓟马等多种害虫,其药效与乐果相近。
