摘要
渗透蒸发是分离液相混合物的膜分离方法，常用于有机物脱水及有机物—有机物的分离。借助于渗透蒸发把化学反应产物部分或全部从反应体系中脱去，可使产物收率不受化学平衡的限制。
Pervaporation is a membrane separation process which can be used to fractionate liquid mixture.The dehydration of organic solvent or the separation of organic—organic mixture by pervapo ration appears to be the most feasible application.Pervaporation is a promising technique for the removal of part of or all products in chemical reaction system.With the aid of pervaporation,the conversion of reactants in an equlibrated reaction may cirumvent the equilibrated conversion.The coupling of an equilibrated reaction with pervaporation is an alternative way to reach complete conversion of reactants.
