摘　　要：盐效应分离是一种新型分离技术。文章系统总结了盐对有机-有机体系气-液和液-液相平衡的影响,进而论述了盐效应在有机-有机体系分离过程的应用,包括加盐萃取精馏和加盐萃取等。最后,展望了盐效应分离有机-有机体系的未来发展。Salt effect separation was a new kind of separation technologies. In this paper, salt effects of organic-organic system vaporliquid and vapor-vapor equilibrium were summarized. Then applications of salt effect in organic-organic system separation were discussed in detail, included extractive distillation with salt and extraction with salt. At last, future research of salt effect for organicorganic system separation was put forward.
