摘要
将过氯乙烯（ＣＰＶＣ）作为渗透汽化膜材料，用于分离乙醇／水溶液，研究了膜对水和乙醇的吸附溶解性能，对乙醇／水溶液的分离性能，分离温度对膜分离性能的影响。发现过氯乙烯膜优先透水，对乙醇／水溶液选择性高而透量较小，膜的稳定性较好。
The pervaporation separation of ethanol/water mixture was tested using a chlorinated PVC(CPVC) membrane.The results show that water is preferential solution and permselectivity in this membrane,while the flux is low. The membrane exhibits good durability for the separation process.
