Date Aug. 8, 1996A process for resolving the racemates of phenylacetonitriles of the formula I I where R1, R2, R3 and m have the meanings stated in the description is described. The process comprises dissolving the racemates I in a polar solvent, adding from 0.5 to 1.0 mol of optically active camphorsulfonic acid per mol of compound I, heating to 40 DEG -100 DEG C., allowing to cool and liberating the optically active phenylacetonitrile I from the salt obtained in this way.
