Para-diethyl benzene
P-di-ethylbenzene is the specialty chemical, its main usage is as a desorbent of producing Para-xylene in Parex process and Fluxy process.
- In addition to obtaining nine international patents in eight countries, the technique of this production further was rewarded with the First National Invention Award of the Republic of China in 1992.
- There are two grades for this product: TSD-980 and TSD-990 with the purities of 98% and 99% respectively. Which are produced by highly selective disproportionation reaction of ethyl benzene.
- This product has been adopted by factories producing para-xylence both domestically and abroad. Numbers of customers has exceeded ten presently.
