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with dissolved and/or entrained carbon monoxide from the first reaction zone; passing at least a portion of the withdrawn liquid reaction composition to a second reaction zone; passing at least a portion of the liquid reaction composition from the second reaction zone into a flash separation zone; wherein the temperature of the liquid reaction composition withdrawn from the first reaction zone is in the range of 170 to 195 DEG C; and the temperature of the liquid reaction composition passed from the second reaction zone to the flash separation zone is at least 8 DEG C greater than the temperature of the |
