菲、蒽、咔唑是重要的染料中间体,其含量的测定有很大的现实意义。菲、蒽、咔唑工业产品的经典化学分析分别用五氧化二碘法、顺丁烯二酸酐法、定氮法来进行测定,但耗时太长无法用于常规分析。虽然菲、蒽、咔唑各类物质的气相色谱法已有报道,但大都是研究同类化合物或同系物的分析,欲对诸类共存的混合物中各组份进行定量分析,则比较困难,笔者也未见报道。本文采用毛细管气相色 Phenanthrene, anthracene and carbazole are important dye intermediates. The determination of their content has great practical significance. Phenanthrene, Anthracene and Carbazole The classical chemical analysis of industrial products was determined by the method of iodine dioxide, maleic anhydride and nitrogen. However, it took too long to be used in routine analysis. Although the phenanthrene, anthracene and carbazole gas chromatography has been reported, but most of the same compounds or homologues of the analysis, the various components of the mixture for a variety of quantitative analysis is more difficult, the author Has not been reported. In this paper, capillary gas chromatography
