ABSTRACT:
A process for preparing acetic acid from methanol and carbon monoxide or a mixed gas of carbon monoxide with hydrogen, which process comprises contacting methanol with a gaseous component selected from a group consisting of carbon monoxide and a mixed gas of carbon monoxide with hydrogen of 2% by volume or less in the presence of a carbon-supported rhodium metal catalyst and methyl iodide promoter in vapor phase under the conditions of a reaction temperature of 180.degree.-220.degree. C., a reaction pressure of 5-10 kg/cm.sup.2 .multidot.G, and a weight of catalyst to feed gas flow rate ratio (W/F) of 10-20 g.multidot.h/mole; and a process for preparing acetic acid from methanol and carbon monoxide, which process comprises contacting methanol with carbon monoxide in the presence of a carbon-supported rhodium metal catalyst, methyl iodide promoter and water in vapor phase.
