摘要

通过液相色谱-质谱联用和其他分析方法，对德累斯顿工业大学历史染料收藏中的各种不同的苯胺染料样品进行了分析，这些样品大多以磷化氢商标注册。结果发现，所分析的染料都是由具有不同甲基数量的化合物组成的混合物。因此，它们是由于含有若干异构体甲苯胺和微量二甲苯胺的技术苯胺氧化而产生的。

Analysis of certain samples of phenazine dyes from the Historical Dyestuff Collection of the Technical University Dresden by liquid chromatography–mass spectrometry

By means of liquid chromatography–mass spectrometry and other analytical methods, a variety of different samples of the phenazine dye Chrysaniline hosted in the Historical Dyestuff Collection of the Technical University Dresden and registered mostly under the trade name Phosphine have been analysed. It was found that all the dyes analysed are mixtures of compounds with different numbers of methyl groups at their phenazine core. They result, hence, from the oxidation of technical aniline that contained several amounts of isomeric toluidines and traces of dimethylanilines.

期刊介绍： The Journal of Chemical Research is a peer reviewed journal that publishes full-length review and research papers in all branches of experimental chemistry. The journal fills a niche by also publishing short papers, a format which favours particular types of work, e.g. the scope of new reagents or methodology, and the elucidation of the structure of novel compounds. Though welcome, short papers should not result in fragmentation of publication, they should describe a completed piece of work. The Journal is not intended as a vehicle for preliminary publications. The work must meet all the normal criteria for acceptance as regards scientific standards. Papers that contain extensive biological results or material relating to other areas of science may be diverted to more appropriate specialist journals. Areas of coverage include: Organic Chemistry; Inorganic Chemistry; Materials Chemistry; Crystallography; Computational Chemistry.
