Abstract

The reaction kinetics for the liquid phase synthesis of methyl acetate for the removal of dilute acetic acid in waste water using a macroporous sulfonic acid ion exchange resin as catalyst was determined experimentally in a continuous stirred tank reactor in temperature range 308-328 K at 101. 325 kPa. The experimental results could be described by a model based on Langmuir- Hinsewood rate expression in liquid phase activities from Wilson method. Based on the model

it was indicated by the simulation of the reaction that catalytic distillation is an effective method for the removal of the acid from waste water.
