Abstract
A method for the vapor-phase carbonylation of lower alkyl alcohols to esters and optionally, carboxylic acids using a catalyst having a platinum on a solid support material as a first component and a vaporous halide as a second component. Desirably, the catalyst includes platinum on an activated carbon support and the vaporous halide is selected from hydrogen halides, alkyl halides and aryl halides having up to 12 carbon atoms, and mixtures thereof.
