Determination of Catalytic Activity Range of Rhodium Catalyst in Homogeneous Methanol Carbonylation to Acetic Acid

To find the optimum operation conditions in rhodium-catalyzed methanol carbonylation, experimental runs were conducted in different constant pressures and temperatures in the catalyst system activation limit. The homogeneous catalytic reactions were performed in a semi-batch manner. Consequently, it is obtained that the rhodium catalyst in homogeneous methanol carbonylation media requires a certain temperature range for activation. Below the lower limit, 420 °K, the reaction does not occur at a reasonable rate and above the upper limit; because of the vapour pressure of the mixture and the absence of sufficient amount of CO the catalyst precipitates.
