Summary:A PROCESS FOR THE PRODUCTION OF ACETIC ACID COMPRISING: INTRODUCING METHANOL AND/OR A REACTIVE DERIVATIVE THEREOF AND CARBON MONOXIDE INTO A FIRST REACTION ZONE CONTAINING A LIQUID REACTION COMPOSITION COMPRISING A CARBONYLATION CATALYST, OPTIONALLY A CARBONYLATION CATALYST PROMOTER, METHYL IODIDE, METHYL ACETATE, ACETIC ACID AND WATER; WITHDRAWING AT LEAST A PORTION OF THE LIQUID REACTION COMPOSITION TOGETHER WITH DISSOLVED AND/OR ENTRAINED CARBON MONOXIDE FROM THE FIRST REACTION ZONE; PASSING AT LEAST A PORTION OF THE WITHDRAWN LIQUID REACTION COMPOSITION TO A SECOND REACTION ZONE; PASSING AT LEAST A PORTION OF THE LIQUID REACTION COMPOSITION FROM THE SECOND REACTION ZONE INTO A FLASH SEPARATION ZONE; WHEREIN THE TEMPERATURE OF THE LIQUID REACTION COMPOSITION WITHDRAWN FROM THE FIRST REACTION ZONE IS IN THE RANGE OF 170 TO 195 °C; AND THE TEMPERATURE OF THE LIQUID REACTION COMPOSITION PASSED FROM THE SECOND REACTION ZONE TO THE FLASH SEPARATION ZONE IS AT LEAST 8 °C GREATER THAN THE TEMPERATURE OF THE LIQUID REACTION COMPOSITION WITHDRAWN FROM THE FIRST REACTION ZONE.
