Ethyl acetate is an important chemical product which is widely used in chemical industry.Ethyl acetate is mainly synthesized via the reactive distillation.However, ethyl acetate,ethanol and water can form ternary azeotrope.So, azeotropic distillation or extractive distillation is always necessary,whereas both of the two processes suffered from high energy consumption.Because of its moderate cost, low energy consumption and no entrainers, pervaporation (PV) has attracted considerable attentions.
