Abstract
Propylene oxide and acetic acid are made by contact between propylene acetaldehyde and molecular oxygen-containing gas in the liquid phase at a temperature from 40 DEG to 150 DEG C., preferably 90 DEG to 130 DEG C., and in a solvent comprising a mixture of methyl acetate and methanol, preferably in the weight ratio 80:20, or a mixture comprising one or more esters, especially the diacetate, of propylene glycol, which esters may be the by-products of the reactions which may in part be recirculated after removal of products boiling below 140 DEG C. Another portion of these by-products can be hydrolysed to propylene glycol and acetic acid. The preferred oxidation pressure is at least 40 ats., especially 80 to 100 ats. The examples use cobalt naphthenate as catalyst.
