摘　　要：醋酸乙烯合成反应过程中,产品中的乙醛含量在催化剂活化期远高于活性期。在理论结合生产实践的基础上,逐一分析了造成催化剂活化期乙醛含量高的原因,提出了优化方法,从而降低了乙醛含量。In the production of vinyl acetate,acetaldehyde content of the product in catalyst induction period was much higher than that in stabilization period.On the basis of theory and production practice,the reasons caused the high acetaldehyde content in catalyst induction period were analyzed and the optimization measures were proposed,by which the acetaldehyde content was reduced effectively.
