ABSTRACT:
The method and apparatus for improving the esterification procedure, in particular for improving the esterification procedure to obtain an ester of low carbon number such as the ethyl acetate and the isopropyl acetate, are provided. By applying the provided method and apparatus, the conversion ratio of the esterification procedure is significantly increased and hence an ester product of a relatively high purity, up to the industrial specification, is obtained.
