The acylation of several disaccharides by ethyl butanoate and ethyl dodecanoate was catalyzed by Candida antarctica lipase in tert-butyl alcohol, at temperatures ranging from 40" to 82ยฐC (reflux temperature). The relative reaction rates of the various disaccharides were directly related to their sol
