A review of para-diethylbenzene production technology

Abstract

Abstract: 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.

Key words: para-diethylbenzene, alkylation, disproportionate, adsorptive separation, isomerisation

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。

关键词: 对二乙苯, 烷基化, 歧化, 吸附分离, 异构化
