Fabrication of Cu3 (BTC)2 Mixed Matrix Membrane and Its Application in Continuous Flow Process

A Cu, ( 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. Cu, ( 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 Cu, ( BTC) 2 MMM heterogeneous catalyst for 24 h. It has an excellent practicality to develop this simple mixed matrix membrane for industrial application.
