| Abstract: | Difunctional hollow fiber composite membranes(PFSA-PVA-SiO2(Al2O3 and TiO2)/PVA/PAN) with catalysis and pervaporation(PV) were prepared,in which employed PAN as support membrane,PVA as separative layer,and PFSA-PVA-nanoparticles(SiO2,Al2O3 and TiO2) as catalytic layer.The separation performances of difunctional membranes were investigated by dehydrating the top product of ethanol-acetic acid esterifiaction reaction,the catalytic activities of them were studied through ethanol-acetic acid esterification reac... |
