The resolution of (R,S)-2-octanol catalyzed by magnetite-immobilized Yarrowia lipolytica lipase in ionic liquids was investigated. The optimal activity and enantioselectivity of the lipase were obtained in a mixture of [EMIM]BF4 and [OMIM]BF4 (v/v = 5:5). Excellent reusability of the enzyme-ionic liquid system was observed in consecutive batch reactions.
