摘要： 在环己烷光氯化制取氯代环己烷的反应精馏工艺中，氯代环己烷的收率随塔内回流量的升高增长缓慢，初步确定体系中存在平行反应. 针对环己烷光氯化反应制取氯代环己烷过程，对氯化液进行了气质联用分析，确定了8种基本的产物组成. 对反应过程进行了宏观分析，认为存在3种平行反应，初步确定了连串-平行反应网络，为该反应的动力学研究和反应精馏耦合生产氯代环己烷工艺的优化提供了依据.

Abstract: The yield of chlorocyclohexane increased slowly with rising of reflux rate during the reactive distillation process of chlorocyclohexane preparation by photochlorination of cyclohexane. Thus, the existence of parallel reactions in this system was confirmed tentatively. The chlorinated liquid from the process for preparation of chlorocyclohexane by photochlorination of cyclohexane was analyzed by gas chromatography-mass spectrometry. The structures of 8 main products were determined. 3 parallel reactions were determined through the macroanalysis of reaction process. The consecutive-parallel reaction network mechanism was determined preliminarily. The present work may present a reference for research of reaction kinetics and optimization of preparation of chlorocyclohexane with reactive distillation process.
