Hydrolysis process of methyl acetate with catalytic distillation can be simulated successfully by a differential model. By means of Muller method in iteratively calculating the conversion of methyl acetate and a certain improvement in resolving the differential equations, many useful results with high precision have been obtained. The improved algorithm shows obvious advantages of stable convergence and rapid calculation speed. Also, a satisfactory simulation between the operating conditions and the hydrolysis conversion and a perfect agreement between computed and experimental data have been achieved by this study.
