Abstract: A catalytic membrane from tungstophosphoric acid (HWP) as the catalyst and poly(vinyl alcohol) as the carrier were prepared by the solvent evaporation method . The effects of HWP/ PVA mass ratio of the catalytic membrane , membrane thickness , the water content in soybean oil , different co-solvents and the addition of the co-solvents on the catalytic performances of HWP /PV A membrane were studied. The experimental results indicated that under the optimum reaction conditions , the conversion of soybean oil reached a maximum of 9O .6% . When the water content of soybean oil was below 5 wt% , the HWP/PVA catalytic membrane could absorb the water in soybean oil, and the water had little effects on the transesterification reaction . The recycling times of the catalytic membrane crosslinked by glutaraldehyde was better than that of non -crosslinked catalytic membrane . The conversion of soybean oil was not significantly decreased after the catalytic membrane crosslinked being used for six runs
