|Abstract:||Candida rugosa lipase-catalyzed esterification of ibuprofen with 1-propanol was conducted in seven ionic liquids and the results were compared with those in isooctane. Although the enzyme showed comparable or higher activity in some ionic liquids compared to that in isooctane, only in the case of [BMIM]PF 6 was the enantioselectivity (E = 24.1) almost twice that (E = 13.0) of isooctane. In another six ionic liquids the enzyme enantioselectivity was much poorer (E = 1.1-6.4). At the same conversion of 30%, E of [BMIM]PF 6 is more than triple that of isooctane. The lipase stability in [BMIM]PF6 was improved by 25% of that in isooctane. It was concluded that [BMIM]PF6 could be applied to substitute the conventional organic solvent (isooctane) in the esterification of ibuprofen. © 2004 Wiley-Liss, Inc.|
