氯氰菊酯是一种高效杀虫剂,在日化及农业等领域被广泛使用。其中,氯氰菊酯的两种α体起主要作用,在合成时要控制工艺条件,以便生成更多的α体,因此要测定其含量,为控制工艺条件提供依据。本文采用硅胶柱,甲不含乙睛的非极性溶剂为流动相,可把氯氰菊酯的四种异构体完全分离,配以已知 Cypermethrin is a highly effective insecticide, which is widely used in the field of daily chemical and agriculture. Among them, the two alpha bodies of cypermethrin play a major role in the synthesis process to control the conditions in order to generate more alpha, so to determine its content, to provide the basis for the control of process conditions. In this paper, silica gel column, a non-polar acetonitrile-free solvent as the mobile phase, the four isomers of cypermethrin can be completely separated, together with the known
