The properties of polyimide membranes and zeolitic membranes prepared on the surface of porous tubular support using the hdrothermal synthesis were evaluated by the pervaporation of methyl tert-butyl ether and methanol mixtures. The experimental results showed NaY zeolite membrane preferentially permeated alcohol in pervaporation and vapor permeation of alcohol/ether or alcohol/benzene mixtures. The high selectivity of the NaY zeolite membrane can be attributed to the selective sorption of alcohol into the membrane. The performance of the NaY zeolite membrane is far superior than any other membrane previously reported. Pervaporation through NaY zeolite membrane provides an alternative to the conventional industrial purification of MTBE and ETBE.The NaY membrane was also characterized by X- ray diffraction and scanning electron microscopy.

通过甲基叔丁基醚和甲醇混合物的全蒸发评价了水热合成在多孔管状载体表面制备的聚酰亚胺膜和沸石膜的性能。实验结果表明，NaY沸石膜在醇/醚或醇/苯混合物的全蒸发和蒸气渗透中优先渗透醇。 NaY沸石膜的高选择性可归因于醇对膜的选择性吸附。 NaY沸石膜的性能远远优于之前报道的任何其他膜。通过NaY沸石膜渗透蒸发提供了MTBE和ETBE的传统工业纯化的替代方案。NaY膜还通过X射线衍射和扫描电子显微镜进行了表征。
