摘 要:二甲基烯丙胺及其盐酸盐合成新工艺张志萍杨伟(四川省化学工业研究设计院成都610041)关键词氯丙烯二甲胺二甲基烯丙胺合成农药中图分类号O623.731二甲基烯丙胺及其盐酸盐,是制备沙蚕毒素类杀虫剂如杀虫双、杀虫单、杀螟丹、杀虫磺、杀虫环等的前体化合物...n improved process for the synthesis of allyl dimethyl amine used in domestic industrial production as an intermediate of dimehypo etc,lumbriconere is heteropoda toxin insecticides is described.The outstanding features are usage of toluene as reaction medium,changing initial temperature of the original process to 15-20℃,instead of 5℃;with liguidliquid phase reaction to replace gasliquid phase reaction.Such being the case,the yield and product quality of new process almost matches with the original one,thus makes refrigeration energy comsumed remarkably reduced and the operation being smooth.
