Abstract

Prepn. of alkanoic acids comprises reacting an alcohol with CO in the presence of a catalyst which comprises (a) >1 Ir cpd. (b) 1 Cu and (c) Br2 and/or I2 or a bromide or iodide cpd., the molar ratio of Br and/or I:Ir being 20:1. The ester, e.g. methyl acetate, may also be formed in the reaction. The catalysts, in proportion to their noble metal content, are more active than known catalysts. The selectivity of the process e.g. to methyl acetate and acetic acid 98-99%, is higher than known processes.
