Immobilization oflipase on a carrier selected from the group consisting of macroporous adsorbent resin of the acrylic type, synthetic epoxy activated resin and Mg&#x2014;Al-hydrotalcite enhances its enantioselectivity by six to seven folds. The immobilizedlipase is suitable for use in resolution of racemic alcohols and/or carboxylic acids, particularly in resolution of racemic menthol or production of menthyl esters.

Method of producing enantioselective immobilized candida rugosa lipase

Wax esters are prepared by reacting a solution of palm oil in an organic solvent with oleyl alcohol in the presence of an immobilized lipase wherein molar ratio of palm oil to oleyl alcohol is between 1:2 and 1:4. Immobilized lipase used is present in an amount which is equivalent to not less than 1000 &#x3bc;g of protein per milli-mole of palm oil used and the reaction is carried out at 40&#xb0; C. to 50&#xb0; C. for a period of not less than 5 hours. The organic solvent used has a value of log P not less than 3.5.
