氯氰菊酯的差向异构化研究

Study on the Epimerization of Cypermethrin

通过差向异构化技术 ,将氯氰菊酯工业原油中无活性的异构体转化成高活性的异构体。经高效液相色谱分析表明 ,转位收率达到 70 % ,高效体产物的纯度达到 90 %。

A high technique of epimerization is used to transfer low effect β hydrogen to high effect α form in the cypermethrin technical product. The results determined by the HPLC show that the yield is more than 70% and high effect α form content is more than 90%.
