Process for preparing propylene oxide and acetic acid

摘要

A process for preparing propylene oxide and acetic acid which comprises oxidation of propylene and acetaldehyde with an oxygen-containing gas in a liquid phase at a temperature of from 70 DEG to 100 DEG C. under a pressure of from 40 to 50 atm in the presence of a catalyst, viz. a boron compound of the formula BE, wherein E is a metal of IV,V,VI Groups of the periodic system, and nitrogen. The process according to the present invention makes it possible to increase selectivity of the formation of propylene oxide as calculated from the reacted acetaldehyde.
