PDEB (Para-diethylbenzene)is a kind of special chemicals which is used as desorbent in producing PX(Para-xylene) .

Our Corporation has a history of six years in producing PDEB which is produced with ethylene & ethylbenzene synthesis method with capacity of 4000MT/a. Our PDEB is sold well not only in domesticmarkets but also in international markets such as India,Korea,Turkey,Holland,America and etc.

In order to further prolong the adesorbent's life degrade the energy and material consume,improve our customer's PX quality,we continously adopt new technology in improving our PDEB's quality and decrease the content of impurties .And from 1997 on,we will adopt the new standard in the production of PDEB.It's as follows:
