Abstract	The experiment described in this paper synthesizes xylitol acylated products from fermentative derived xylitol and acid anhydrides of various chain lengths in the presence of Tetrahydrofuran (THF) and acetonitrile using immobilized Pseudomonas aeruginosa (PL) lipase as a biocatalyst (97% residual activity up to five cycles) at 37°C, 200 rpm. This study examines a number of different acid anhydrides for their highly selective and efficient lipase-catalyzed acylation of primary hydroxyl groups in xylitol. Of those studied, the best results are obtained with butanoic anhydride, 80.12% after 4 h in acetonitrile followed by vinyl acetate, which results in 77.79% conversion after 8 h of incubation in THF as analyzed through high performance liquid chromatography (HPLC).
