Kinetic resolution of transesterification reaction of trans-paroxol catalyzed by lipase in organic media
摘要
Abstract
The kinetic resolution of transesterification reaction of trans-paroxol catalyzed by lipase was studied in organic media.The influence factors including enzyme source,solvent,acyl donor, temperature,substrate and the molar ratio of substrate with acyl donor were researched.The optimal conditions were obtained as following:Acetonitrile as solvent, viny acetate as acyl donor,concentration of substrate of 40mmol/L,the molar ratio substrate with acyl donor of 1∶8 and reaction temperature 30℃.The conversion,the ees and the E value reached 48.1%,53.3%and 6.20 under the optimal conditions after 8h.关键词
