【Abstract】 Based on the success of the pilot plant, the industrial experiments of the new process of catalytic distillation of methyl acetate hydrolysis was studied. The catalytic distillation tower is 1?000?mm in diameter, 22?000?mm in height. Catalyst-bundle of ion exchange resin was packed in a column as catalytic distillation section and Mo-Ti metal plate structured packing was packed in a column as stripping section. The influence of the factors, such as the feed mole ratio of water to methyl acetate, the ratio of top reflux to feed methyl acetate and the feed space velocity of methyl acetate, on the conversion of methyl acetate and weight ratio of acetate acid to water in the hydrolysis mixture were researched. Experiment results show that the conversion of methyl acetate can increase from 23%-25% to 57%-64%. And the computer simulation was applied to simulate the new process. 更多还原
