The hydrolytic kinetics experiments for methyl acetate with 001×7(732) cationexchange resin were carried out in a batch fullystirred reactor in the ranges of 40—55℃ of reaction temperature

100—600 g·L-1 of catalyst concentration and 0.5∶1—9.0∶1 of molar ratio of water to MeOAc

while the effect of resin particle size was neglectedBased on some experimental phenomena and absorption characteristics of some components on catalytic sites in the process of hydrolysis reaction

one pseudohomogeneous and two heterogeneous hydrolytic kinetic models were established

and the parameters were estimated based on experimental dataAn optimal heterogeneous hydrolytic kinetic model

which showed good agreement with the experimental data

was obtainedThe optimal model was based on the proposed mechanism that both methyl acetate and water were absorbed on catalytic sites and the surface reaction was the ratecontrolling stepSome operational parameters of methyl acetate catalytic hydrolysis with 001×7(732) cationexchange resin were optimized through the simulation calculations based on this modelThe obtained optimal values were as follows: 55℃ of reaction temperature

260 g·L-1 of catalyst concentration and 1.5∶1 of molar ratio of water to MeOAcUnder the conditions of the optimized operation parameters

the hydrolytic conversion of methyl acetate reached 348% close to the equilibrium hydrolytic conversion after 90 min of the hydrolysis reaction. .
