ABSTRACT:
While supplying methanol and carbon monoxide via feed lines17and19, respectively, to a liquid phase reaction system3including a carbonylation catalytic system, and maintaining a substantially constant liquid level of the reaction system, part of the reaction mixture containing the produced acetic acid is drawn out from the reaction system and supplied to a flash distillation column4, and the high boiling point component, which contains the carbonylation catalytic system that has been separated by ths flash distillation, is circulated to the reaction system3by means of a circulation line21. At circulation line21, the flow rate is detected by a flow rate sensor F3and the temperature is detected by a temperature sensor T2, and based on the detection data, a control unit8is used to control the temperature of the circulated high boiling point component by means of a temperature regulating unit6and thereby to suppress temperature and pressure fluctuations of the above-mentioned reaction system.
