摘　　要：采用萃取精馏和催促精馏相结合的分离集成技术从碳九芳烃中分离均三甲苯。考察了理论塔板数、回流比、萃取剂/进料/催促剂比(质量)对塔顶塔釜均三甲苯产物纯度的影响。结果表明,可得到纯度大于98.0%的均三甲苯产品,适宜的理论板数为102块、适宜的回流比为15、适宜的萃取剂/进料/催促剂比(质量)为7∶1∶0.3。本研究为进一步中试提供了依据。The integrated separation technology which combined extractive distillation and urging fractionation was used to separate mesitylene from C9 arene.The effects of number of theoretical plate,reflux ratio and extractant/feed/urging solvent ratio（mass fraction）on the purity of mesitylene product from top and bottom of composite separation tower were investigated.Mesitylene product of purity over 98.0% was obtained.The number of optimal theoretical plate was 102.Optimal reflux ratio was 15.Optimal extractant/feed/urging solvent ratio was 7∶1∶0.3.The study could provide a basis for further pilot plant test.
