a new type of semi-batch membrane reactor has been developed for the synthesis of short chain alcohol fatty acid esters. the synthesis of n-butyl oleate was carried out in the reactor at a temperature of 30 $degree$ c. the reaction was catalyzed by mucor miehei lipase, which was immobilized on the membrane walls in the form of macroscopically thick ultrafiltration cake. the ester remained in the bulk phase; water, as a second product, was separated from the oil phase by diffusion through the membrane walls. at the optimal reaction mixture, with molar fraction of oleic acid of 0.55, a conversion of 88.11 was reached in a relatively short time (author abstract) 10 refs
