Abstract
A solid supported catalyst suitable for the vapor phase carbonylation of lower aliphatic alcohols, ethers, ester, and ester-alcohol mixtures, and desirably, methanol, to produce carboxylic acid, esters and mixtures thereof. The solid supported catalyst includes an effective amount of gold associated with a solid support material in the presence of a halide promoter. Desirably, the support material is selected from carbon, activated carbon, pumice, alumina, silica, silica-alumina, magnesia, diatomaceous earth, bauxite, titania, zirconia, clay, magnesium silicate, silicon carbide, zeolites, ceramics and combinations thereof.
