Abstract
A catalyst comprising an effective amount of iridium and at least one second metal selected from the Lanthanide Series of the Periodic Table is useful for vapor phase carbonylation to produce carboxylic acids and esters from lower alkyl alcohols, ethers and ester-alcohol mixtures. The iridium and secondary metal are deposited on a support material, preferably carbon. In a preferred aspect of the invention, the catalyst is useful for vapor phase carbonylation to produce acetic acid, methyl acetate and mixtures thereof.
