    Abstract: A process is disclosed for separating racemates of phenyl acetonitriles having 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 ~C, letting it cool down and extracting the optically active phenyl acetonitrile (I) from the thus obtained salt.
