摘　　要：介绍了对二乙苯市场需求情况、生产技术现状及其最新研究成果,重点评述了乙苯-乙烯烷基化法、乙苯-乙醇烷基化法、乙苯歧化法、吸附分离法及吸附分离-异构化法等已经工业化的对二乙苯生产技术。通过对比分析,认为吸附分离-异构化法生产过程无副产物间二乙苯和邻二乙苯采出,生产成本最低,是生产对二乙苯最为经济有效的方法。The market demand of para-diethylbenzene,production technology and its latest research situation were introduced. The key industrialized production methods , adsorption method of separation-isomerization were compared , including ethylbenzene-ethylene alkylation method , ethylbenzene-ethanol alkylation method,disproportionation of ethylbenzene method and adsorption method of separation. The results showed that the adsorption separation-isomerization process,with the lowest cost and no byproduct,is the most economic and effective method for para-diethylbenzene production.
