摘要
用硅沸石（silicalite－1）填充的硅橡胶膜对乙酸乙酯-水进行渗透蒸发分离，考察了沸石填充量对膜分离性能的影响．实验结果表明，用硅沸石填充的硅橡胶膜处理低浓度的乙酸乙酯水溶液，能迅速地降低溶液中乙酸乙酯的浓度，得到高浓度的乙酸乙酯渗透液．硅沸石分离膜具有很高的选择性，在节能、环保等方面具有广阔的应用前景．
The ethyl acetate-water system has been separated by pervaporation using zeolitesilicalite-1 filled PDMS membrane, The effect of zeolite content in the silicone rubber membrane was studied. The results show that using the membrane to treat low concentrationethyl acetate-water solution can quickly reduce the content of ethyl acetate in solution andobtain a permeate with high content of ethyl acetate. It shows that zeolite silicalite-1 filledPDMS membrane has a very high selectivity on removing ester from waste water and recovering it. The fact indicates that pervaporation by the membrane will have a widely use in energy-saving and environmental protection.
