Metal Zeolite Catalysts
Published in Subhash Bhatia, Zeolite Catalysis: Principles and Applications, 2020
Carbonylation of methanol has in recent years become a commercially important route for the production of acetic acid and methyl acetate. Industrial catalysts are at present homogeneous, based on cobalt and more recently rhodium compounds. The cobalt catalysts are less active and require more severe operating conditions (i.e., 250°C, 650 to 750 atm) than the rhodium-based catalysts (170 to 250°C, 7 to 14 atm).

We consider the reaction of acetic acid with methanol to obtain methyl acetate based on [8]. This process, which is a chemical equilibrium, can be carried out through a reactive distillation, so that methyl acetate will be eliminated from the reactor and recovered as gas, as reaction moves forward and the equilibrium is displaced to the products formation. It can be achieved because the methyl acetate boiling point is lower than the reactants, enabling the elimination of the methyl acetate from the reactor while the reaction takes place. The reaction occurs as follows: CH3−COOH+CH3OH↔CH3−COOCH3↑+H2O

The esterification of acetic acid with methanol synthesizes the renowned ester, methyl acetate. It is used in various perfumes and cosmetic industries, as plasticizers and in the paint industry. Due to its volatility and low toxicity, it is also used as a solvent in glues. Moreover, it has also been proven as one of the successful fuel additives used for compression-ignition engines (Jagadeesh Babu et al., 2011; Verma et al., 2017).
