摘　　要：介绍了乙炔和氯化氢合成氯乙烯过程中,由于触媒中所含HgCl2的损耗而造成触媒活性降低的原因及延长其使用周期的关键因素和工艺方法。In the systhesis of vinyl chloride from acetylene and hydrogen chloride, the loss of HgCl2 in catalysts could lead to the decrease of catalyst activity. In this paper, the reasons for the decrease of catalyst activity were introduced as well as the key factors and process methods to pro-long their service lives.
