VAPOR PHASE CARBONYLATION PROCESS USING GOLD CATALYSTS

摘要

Disclosed herein is a vapor phase carbonylation process useful for producing carboxylic acids, esters and mixtures thereof from lower aliphatic alcohols, ethers, ester, and ester-alcohol mixtures. The vapor phase carbonylation process is characterized in that it utilizes a solid supported catalyst having an effective amount of gold associated with a solid support material.
