    Abstract: A process is disclosed for separating racemates of phenyl acetonitriles havi ng the formula (I), in which R1, R2, R3 and n have the meaning given in the description. The process consists in dissolving the racemates (I) in a polar solvent, adding thereto 0.5 to 1.0 mole of optically active camphosulphonic acid per mole of compound (I), heating the mixture up to 40 to 100 .degree.C, letting it cool down and extracting the optically active phenyl acetonitrile (I) from the thus obtained salt.
