Abstract

Abstract : The Cu3 (BTC)2 /cellulose acetate mixed matrix membranes were fabricated for the acetalization of aldehydes. Abstract : Metal–organic framework (MOF)-based mixed matrix membranes (MMMs) were fabricated by a combination of Cu3 (BTC)2 MOF and polymer cellulose acetate. The cellulose acetate in the MMMs served as the matrix and the Cu3 (BTC)2 MOF as the filler. The as-synthesized MMMs were utilized as a heterogeneous catalyst for aldehyde acetalization. The characterization techniques indicated that the Cu3 (BTC)2 crystals were uniformly dispersed in the MMMs. The BET surface area of the Cu3 (BTC)2 -based MMM was measured to be 459 m 2 g −1 at 60 wt% Cu3 (BTC)2 loading. Furthermore, the MMMs served as an excellent catalyst under our continuous flow catalytic reaction conditions. The optimal catalytic result of benzaldehyde yield reached 94% with 60 wt% Cu3 (BTC)2 loading of the MMMs at room temperature and the benzaldehyde diethyl acetal reached 0.59 mmol min −1 gCu-BTC −1 .
