环氧丙烷 (PO)是重要的有机化工原料和中间体 ,目前工业采用氯醇法和间接氧化法生产。这两种方法均存在严重缺陷 ,有待于改进。本文主要介绍丙烯直接氧化法制取PO的近期进展 ,指出了丙烯直接氧化法研究的难点和今后研究的方向。
Propylene oxide (PO) is an important organic chemical raw materials and intermediates, the current industrial use of chlorohydrin and indirect oxidation production. Both of these methods have serious flaws and need to be improved. This article mainly introduces the recent progresses in the preparation of PO by the direct oxidation of propylene and points out the difficulties in the direct oxidation of propylene and the future research directions.
