A PROCESS FOR THE PRODUCTION OF ACETIC ACID BY CARBONYLATING METHANOL AND/OR A REACTIVE DERIVATIVE THEREOF WITH CARBON MONOXIDE IN A CARBONYLATION REACTOR CONTAINING A LIQUID REACTION COMPOSITION COMPRISING AN IRIDIUM CARBONYLATION CATALYST, METHYL IODIDE CO-CATALYST, A FINITE CONCENTRATION OF WATER, ACETIC ACID, METHYL ACETATE, AT LEAST ONE PROMOTER SELECTED FROM RUTHENIUM, OSMIUM AND RHENIUM AND A STABILISING COMPOUND SELECTED FROM THE GROUP CONSISTING OF ALKALI METAL IODIDES, ALKALINE EARTH METAL IODIDES, METAL COMPLEXES CAPABLE OF GENERATING 1-, SALTS CAPABLE OF GENERATING 1-, AND MIXTURES OF TWO OR MORE THEREOF WHEREIN THE MOLAR RATIO OF PROMOTER TO IRIDIUM IS GREATER THAN 2 : 1, AND THE MOLAR RATIO OF STABILISING COMPOUND TO IRIDIUM IS IN THE RANGE [GREATER THAN 0 TO 5] : 1.
