Abstract

An improved process for the esterification of carboxylic acid and alcohol into carboxylic ester is disclosed. It comprises the steps of: (a) charging the esterification reactants into a fixed bed reactor under a predetermined reaction condition; and (b) reacting the esterification reactants in the fixed bed reactor. The fixed be rector contains acidic catalysts that are present in the solid phase, and the reaction conditions are controlled such that (I) the reactants and the products co-exist in a gas-liquid tow phase equilibrium in the fixed bed reactor and that (ii) at least one component of the reactants is present in another phase. Because a phase change is always taking phase concurrently with the esterification reaction, the reaction stream is maintained at a relatively uniform temperature. This greatly reduces the chances of catalyst poisoning and minimizes the formation of undesired by-products such as polymers/oligomers and ethers, which are often produced at high temperature. The concurrent phase change also contributes to the extremely high reaction yield and selectivity, typically better than 90% observed in the present invention.
