醚菊酯的合成研究

The Synthesis of Insecticide Ethofenprox

醚菊酯是目前在拟除虫菊酯中药效优异、对鱼类低毒的一种高效杀虫剂。通过对合成醚菊酯的4条工艺路线进行了对比, 最终确定以邻氯苯酚为起始原料制备高效菊酯杀虫剂醚菊酯。此路线合成总收率25%, 纯度大于95%, 该工艺具有工业化可行性。

Ethofenprox was advanced insecticide in the pyrethroids for the present because it had very well efficacy andlow toxicity to fish. Comparative the four methods In synthesis trebon. Ethofenprox was prepared by using o-chlo-rophenol as start material. The yield was 25% and quality was above 95%, the process was easy to industrialize.
