HYDROCARBONYLATION OF DIMETHYL ETHER

摘要

Oxygenated acetyl compounds ethylidene diacetate, acetic acid, acetic anhydride, acetaldehyde, and methyl acetate are produced directly from synthesis gas and dimethyl ether in a catalyzed liquid phase reaction system. The inclusion of carbon dioxide in the synthesis gas in selected amounts increases the overall yield of oxygenated acetyl compounds from the reactant dimethyl ether. When methanol is included in the reactor feed, the addition of carbon dioxide significantly improves the molar selectivity to ethylidene diacetate.
