Stereospecific esterification of dl-menthol was studied by the use of immobilized lipase in an adequate water-saturated organic solvent system. Lipase from Candida cylindracea immobilized by entrapment with urethane prepolymers and 5-phenylvaleric acid as the acyl donor were chosen based on the stereoselectivity and the yield of l-menthyl ester. Water-saturated cyclohexane or isooctane was found to be the most suitable solvent system. Entrapment significantly enhanced the operational stability of lipase.
