    • A process for producing an optically active alcohol comprising carrying out interesterification between a racemic alcohol and an ester selected from the group consisting of (a) a diester between a lower monohydric alcohol and a saturated dicarboxylic acid having 14 or more carbon atoms, (b) a triglyceride of a saturated fatty acid having 16 or more carbon atoms, and (c) a monoester between a lower monohydric alcohol and a saturated fatty acid having 18 or more carbon atoms in the presence of lipase, preferably heat-resistant lipase, and in the presence or absence of a solvent, preferably in the absence of a solvent, under a substantially water-free condition, separating an optically active alcohol rich in either one of R- and S-forms from the reaction mixture, and adding an optically inactive non-racemic alcohol to the residue of the previous step to carry out interesterification under the same conditions as in the previous reaction to separate the other enantiomer. According to the present invention a racemic alcohol can easily be resolved into each enantiomer with high purity in good yield.

    • A process for producing an optically active alcohol having a phenyl group is disclosed, comprising the step of carrying out interesterification between (a) a monoester between a racemic alcohol having a phenyl group and a fatty acid or a diester between a racemic alcohol having a phenyl group and a dibasic acid and (b) an optically inactive non-racemic alcohol having 16 or more carbon atoms in the presence of heat-resistant lipase and in the absence of a solvent under a substantially water-free condition at a temperature of not lower than 81.degree. C. under atmospheric pressure or reduced pressure and the step of separating an optically active alcohol having a phenyl group rich in either one of R- and S-forms from the reaction mixture. Use of heat-resistant lipase makes it possible to use high-melting point materials without using any solvent therefor and to perform interesterification at a high temperature thereby completing the reaction in a reduced time. Further, use of a high-melting point and high-boiling point starting material makes it possible to separate an optically active alcohol from the reaction mixture with high purity in high yield by means of a simple purification step taking advantage of a difference in physical properties.
