Based on the success of the industrialization of the process of catalytic distillation of methyl acetate hydrolysis, the new process of catalytic distillation of methyl acetate and methanol azeotrope hydrolysis and related fundamental research were studied. These can make further improvement on the process in order to simplify the process and reduce the energy-consumed of the recovery system. In addition, theoretical system of the simulation and design the catalytic distillation process were established, which can provide the basis of the pilot plant and industrialization in the future.
