ABSTRACT:
Process for preparing an aliphatic carboxylic acid having (n+1) carbon atoms, where n is an integer up to 6, and/or the ester derivative thereof by contacting an aliphatic alcohol having n carbon atoms and/or a reactive derivative thereof selected from dialkyl ether, ester of the alcohol and an alkyl halide with carbon monoxide in the presence of a catalyst. The catalyst consists of mordenite which has been ion- exchanged or otherwise loaded with silver.
