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