The composition of a technical alkylchlorobiphenyl mixture, proposed as a substitute for polychlorinated biphenyls, has been investigated by spectral and chromatographic methods. Gas-liquid chromatography-mass spectrometry revealed the presence of a large number of biphenyls substituted with 2-3 chlorine atoms and 0-4 isopropyl groups. The mixture was dechlorinated as a first step toward structure elucidation of the individual components. The behavior of the alkylchlorobiphenyls during analytical cleanup steps such as thin layer chromatography and chromic acid oxidation was also investigated.
已通过光谱和色谱方法对一种提议用作多氯联苯替代品的工业用烷基氯联苯混合物的成分进行了研究。气液色谱 - 质谱分析表明，该混合物中存在大量被2 - 3个氯原子和0 - 4个异丙基取代的联苯。作为阐明各组分结构的第一步，对该混合物进行了脱氯处理。还研究了烷基氯联苯在分析净化步骤（如薄层色谱和铬酸氧化）中的行为。
