PCT No. PCT/FR95/00625 Sec. 371 Date May 14, 1997 Sec. 102(e) Date May 14, 1997 PCT Filed May 15, 1995 PCT Pub. No. WO95/31426 PCT Pub. Date Nov. 23, 1995Preparation of carboxylic acids or corresponding esters by reacting an alcohol with carbon monoxide in the presence of an iridium catalyst and a halogen promoter. The reaction involves a reaction mixture composed of more than 0% to 10% water, more than 0% to 10% halogen promoter, 2% to 40% of an ester corresponding to the reaction of alcohol with the acid, soluble iodides in an amount such that the atomic ratio of iodides to iridium varies between more than 0 and 10, the carboxylic acid being used as the reaction solvent.
