The best choice for separating diethylbenzene is the adsorptive separation by zeolite adsorbents in high efficiency.

指、节能分子筛吸附分离法是分离二最佳选。

The transalkylation of polyethylbenzene, mainly diethylbenzene and triethylbenzene, with benzene catalyzed by tungstophosphoric acid has been studied in stirred autoclave.

采用搅拌压釜,以磷钨酸为催化剂,研究了与多烷基转移反应,多主要是二和三。
