摘　　要：采用反应分离方法 ,用氯代烷对富集均三甲苯进行了精制。在选定催化剂和反应温度、反应时间后 ,当氯代烷与甲乙苯的摩尔比为 1.4时 ,氯代烷对富集均三甲苯的精制起到了较佳的作用 ,甲乙苯的转化率超过99% ,也使偏三甲苯高效异构化均三甲苯 ,使均三甲苯的产率在 116 %以上 ,反应液中均三甲苯与C9芳烃的质量比超过 98.9%Enriched misitylene was refined by reaction with chloroalkane.After selecting catalyst, reaction temperature and time,chloroalkane took better effects when molecular ratio of chloroalkane to methyl ethyl benzene was 1.4.Convertion of methyl ethyl benzene was over 99%,unsym-trimethyl benzene was efficiently isomerized to mesitylene,so that the yield of mesitylene was over 116%,and mass ratio of mesitylene to C 9 arene was over 98.9% in reaction product solution.
