An industrially highly advantageous process for producing optically active substances with a high optical purity conveniently, which comprises treating an enantiomeric mixture of 3-chloro-1-(substituted)-phenyl-1-propyl esters of a saturated or unsaturated fatty acid with an enzyme which can asymmetrically hydrolyze the mixture, such as a lipase originating in the microorganism belonging to the genus Pseudomonas, Aspergillus, Candida or Chromobacterium to give a mixture containing optically 3-chloro-1-(substituted)-phenyl-1-propanol and optically active 3-chloro-1-(substituted)-phenyl-1-propyl ester of a saturated or unsaturated fatty acid, and separately recovering the optically active propanol or its derivative and the optically active propyl ester or its derivative from the mixture.
