Catalytic Esterification of Methyl Alcohol with Acetic Acid

Abstract

Abstract: Esterification of methyl alcohol with acetic acid catalysed by Amberlyst-15 (cation-
exchange resin) was carried out in a batch reactor in the temperature ranging between 318－
338 K, at atmospheric pressure. The reaction rate increased with increase in catalyst
concentration and reaction temperature, but decreased with an increase in water
concentration. Stirrer speed had virtually no effect on the rate under the experimental
conditions. The rate data were correlated with a second-order kinetic model based on
homogeneous reaction. The apparent activation energy was found to be 22.9kJ.mo1-1 for the
formation of methyl acetate. The methyl acetate production was carried out aa batch and
continuous in a packed bed restive distillation column with high purity methyl acetate
produced.

Key words: reactive distillation, acetic acid, esterification, polymeric catalyst
