气相色谱单柱快速分析吡虫啉中间体

Rapid Analysis of Two Intermediates of Imidacloprid by GC

本文提出了在同一条件下２－（Ｎ，Ｎ－二甲基）氨基－５－甲基吡啶（Ⅰ）和２－氨基－５－甲基吡啶（Ⅱ）气相色谱分析方法。本方法以１０％ＯＶ－１０１／ＣｈｒｏｍｏｓｏｒｂＷＡＷＤＭＣＳ为固定相，采用程序升温法实现对３－甲基吡啶、Ⅰ。

This paper reports the gas -chromatographic determination of 3-methyl pyridine,2-(N,N-dimethyl)amino-5-methylpyridine,2-amino-5-methyl pyridine and impurities in the same condition by using a column of 10% OV-101 on Chromosorb W AW DMCS and programmed temperature analysis.
