摘　　要：在分析渗透汽化膜分离有机混合物体系类型的基础上,重点提出有机液优先透过渗透汽化膜,其作为渗透汽化膜的重要组成部分近年来受到高度关注。综述了各种有机物优先透过的膜材质、分离特性,以及近年来有机液优先透过膜的研究进展和应用领域。通过分析可以得出结论:有机液优先透过渗透汽化膜的研究目前尚处于基础研究阶段。提高膜的选择性和渗透通量,以及如何使两者取得适度平衡等是当前研究的重点。As an important part of pervaporation membranes, the organic permselective pervaporation membranes receive serious attention recently. Both the separation characteristics of various mixture systems through different membrane materials and the research development about organic permselective pervaporation membranes in recent years are discussed. As a result, the pervaporation membranes and their processes are in the basic research phase. Im- proving the permeation flux and selectivities of membranes and achieving moderation balance between them are the Important points in the present study.
