Abstract
A process for preparing a carboxylic acid have (n+1) carbon atoms by reaction of carbon monoxide with an alcohol having n carbon atoms in the presence of a rhodium catalyst which process comprises feeding the alcohol and / or an ester of the alcohol and the carboxylic acid together with carbon monoxide to a carbonylation and removing the carboxylic acid from the carbonylation reactor characterized in that the carbonylation reactor contains during the course of the process a liquid reaction medium comprising: (a) at least a finite quantity of water (b) a catalyst stabilizer selected from the group consisting of quaternary ammonium iodides having the formula
