摘要： 利用微波辅助水热合成法制备了高性能的a&b取向的T型分子筛膜. 并用于乙酸与正丁醇的渗透汽化耦合反应,结果表明, T型分子筛膜可以有效地从反应混合物中脱出产物水,其它反应物与产物仍留在反应体系中,反应转化率可以达到100%.

Abstract: High-performance a&b-oriented zeolite T membranes were prepared by the microwave-assisted hydrothermal method. The membranes were applied to the pervaporation-assisted esterification of acetic acid and n-butyl alcohol at 383 K. Zeolite T membranes could effectively remove water product from the reactant mixtures and improve the conversion of acetic acid to 100% without the loss of reactants or products.
