Factors affecting the resolution of dl-menthol by immobilized lipase-catalyzed esterification in organic solvent.

Among 10 lipases tested, Candida rugosa lipase exhibited the best ability to catalyze the resolution of dl-menthol in organic solvent. The lipase was immobilized on different carriers, and the experiment was carried out with different acyl donors. The high yield and optical purity of the product were achieved in cyclohexane with valeric acid as acyl donor using C.
