摘要
用多元酸作交联剂与聚乙烯醇（ＰＶＡ）进行反应制得渗透汽化膜，对水－乙醇进行渗透汽化分离。研究了膜溶胀平衡过程，考察了料液组成对膜渗透汽化性能的影响。
The pervaporation separation of water-ethanol mixture was carried out using PVA membrane crosslinked by multinary acid. The swelling equilibrium of the membrane and the effects of feed composition on the separation properties were examined.
