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.
