摘要：

The resolution of 1,1'-binaphthyl-2-yl(phenyl) methanone O-acetyl oxime catalyzed by lipase in three different ionic liquids, 1-butyl-3-methylimidazolium hexafluoride-phosphate, [bmim][PF6], 1-butyl-3-methylimidazolium tetrafluoroborate, [bmim][BF4] and N-butyl-pyridium hexafluorophosphate, [BuPy][PF6] and organic solvents was studied. The lipase shows low activity in ionic liquids and organic solvent with ionic liquids as the additive, while the lipase coated with ionic liquids gives the best enantioselectivity as high as 95%
