摘　　要：简要介绍了平衡氧氯化法生产氯乙烯(VCM)的生产方法。综述了平衡氧氯化法VCM生产中催化剂的开发与应用,主要是氧氯化反应中加入添加助催化剂的新型多组分催化剂,使反应率大大提高以及裂解反应中加入催化剂用以提高反应率和减少副产物;VCM生产中各个单元工艺方法的改进,包括利用反应热为精馏提供热源,采用双效变压精馏技术,增加热回收装置等措施,其主要目的是减少蒸气损耗量以及增加热量的回收再利用。Briefly introduced the production method of balanced oxychlorination producing Vinyl Chloride Monomer（VCM）. Summarized the catalyst development and the application in the VCM production, mainly in the oxychloride reaction adds the new type multi-components catalyst to expedite the reaction rate greatly and in the decomposition response adds the catalyst to enhance the reaction reactivity rate and reduce the by-product. In the VCM production each unit technique improvement, including provides the heat source using the reaction heat for distillation, using double avail pressure change distill technology, adding heat recovery equipment and so on .Their main goal is to reduce the steam loss and increase the thermal recycling uses. Finally fercast the research on the balanced oxychlorination producing VCM.
