摘要
介绍了目前世界PTA生产现状和将来的发展。同时指出,近30年来,DMT和PTA虽同为聚酯工业的两大原料,但PTA的年增长率一直高于DMT,今后的发展将以PTA为主。并以二甲苯(PX)氧化制对苯二甲酸(TA)再经精制制精对苯二甲酸(PAA)的工艺路线为主,重点介绍了PX中温氧化工艺和TA精制技术的进展,提出了在TA精制技术中应注意的几个问题。
The present production and future development of PTA in the worldare introduced. It is said, both DMT and PTA are the raw materials in PETproduction, but annual rate of increase of PTA has been being higher thanDMT in late thirty years and PTA will be mainly developed in the futu-re. Emphasis are given to the developments on middle temperature oxida-tion process of PX and refining technique of TA in the process line ofmaking PTA from PX, and some points for attention in refining techniqueare put forward.
