The carbonylation of methanol using a sodium methoxide catalystwas studied in the temperature range of 60-110℃ and pressure range of2.0-4.0Mpa in a mechanically agitated reactor. A Kinetic rate expression forthe reaction is presented. The apparent activation energies for thecarbonylation and decarbonylation reactions were found to be 70.7kJ/moland 92.1 kJ/mol respectively. The negative effects of CO2 and H2O on thecarbonylation reaction were studied. The impurities react with the sodiummethoxide catalyst and stop the reation.
