Abstract

Abstract Several types of imidazolium salt ionic liquids were prepared derived from poly (oxyethylene) alkyl sulfate and used as an additive or coating material for lipase-catalyzed transesterification in an organic solvent. A remarkably increased enantioselectivity was obtained when the salt was added at 3–10 mol% versus substrate in the Burkholderia cepacia lipase (lipase PS-C)-catalyzed transesterification of 1-phenylethanol by using ...
