摘要:

采用溶剂蒸发法制备了Cu3(BTC)2质量分数为60%的Cu3(BTC)2@PS复合基质膜, 并对其形貌和结构进行了表征. 结果显示, Cu3(BTC)2 均匀分布于复合基质膜中且具有较好的热稳定性. 以醇醛缩醛化反应为探针反应, 测试了复合基质膜的催化性能, 结果表明, 在该膜催化下苯甲醛的转化率高达99%, 苯甲醛二乙缩醛的选择性为99%. 此类催化膜具有良好的实用性, 能实现连续24 h高效率生产苯甲醛二乙缩醛, 可将其应用于工业上的连续化生产.

Abstract:

A Cu3(BTC)2@PS mixed matrix membrane(MMM) with 60%(mass fraction) MOF loading was fabricated via solvent evaporation method. The catalyst was characterized by means of SEM, XRD, FTIR and TGA. The results showed that Cu3(BTC)2 MOF uniformly distributed on the MMM and the MMM possessed a good thermal stability. The copper of the Cu-BTC MMM served as the active sites for the flow reaction system. The as-synthesized membranes possess high surface area and excellent hydrophilicity. Cu3(BTC)2 MMM was evaluated as a catalyst for the aldehyde acetalization with ethanol. 99% conversion of benzaldehyde and 99% selectivity of benzaldehyde diethyl acetal was obtained, using Cu3(BTC)2 MMM heterogeneous catalyst for 24 h. It has an excellent practicality to develop this simple mixed matrix membrane for industrial application.
