Abstract
A solid catalyst comprising an effective amount of iridium and at least one second metal selected from gallium, zinc, indium and germanium associated with a solid support material is useful for vapor phase carbonylation to produce carboxylic acids and esters from alkyl alcohols, esters, ethers or ester-alcohol mixtures. The iridium and at least one second metal are deposited on a support material. In some embodiments of the invention, the catalyst is useful for vapor phase carbonylation.
