<p>A process for preparing carboxylic acids (eg acetic acid) from alcohols (eg methanol) by carbonylation is provided. The process employs a catalyst comprising rhodium and nickel supported upon a carbon, preferably a high surface area carbon. The process described is carried out in the presence of hydrogen and a halide promoter leading to high yields of the carboxylic acid under very mild conditions (1 to 50 atmospheres, 150-300 DEG C).</p> |
