Popis:	Lipase could catalyze the ammonolysis of trimethylsilylmethyl acetate in organic solvents and Novozym 435 was the best biocatalyst for the reaction. The influences of some factors on the reaction were investigated. Cyclohexane, n-hexane and heptane were found to be suitable reaction media and ammonium carbamate was the best ammonium source. The optimal initial water activity, temperature and pH value were 0.55–0.75, 35°C and 6.5 respectively, under which a substrate conversion of 97.6% could be achieved after reaction for 140 h.
