硝基氯苯是重要化工原料,但常常是三种异构体的混合物,在生产和使用中往往要求控制和测定各异构体的含量。气相色谱法是分离和测定三种异构体的较好方法。在文献中对这三种异构体的分离已有一些报道。南京化工厂用己二酸乙二醇聚酯分离和测定这三种异构体,但分析周期较长。我们曾用芳羧酸酯液晶成功地分离和测定了一硝基甲苯的三个异构体和二叔丁基二茂铢的 Nitrochlorobenzene is an important chemical raw material, but often is a mixture of three isomers, often require the control and determination of the content of each isomer in the production and use. Gas chromatography is a better way to separate and determine three isomers. Separation of these three isomers has been reported in the literature. Nanjing Chemical Plant with ethylene glycol adipate polyester separation and determination of these three isomers, but the analysis cycle is longer. We have successfully separated and measured three isomers of mononitrotoluene and di-tert-butyl bibo
