A PROCESS IS PROVIDED FOR THE DISTILLATIVE SEPARATION OF PENTENE NITRILE ISOMERS WHICH HAVE A RELATIVE VOLATILITY ALPHA RANGING FROM 1.0 TO 1.3 IN THE PRESSURE RANGE FROM 1 TO 500 kPa, WHEREIN THE DISTILLATION IS CARRIED OUT IN THE PRESENCE OF A LIQUID DILUENT WHICH FROMS WITH THE PENTENE NITRILE ISOMERS, UNDER THE SAME PRESSURE CONDITIONS, AZEOTROPES WHOSE RELATIVE VOLATILITY ALPHA IS HIGHER THAT OF THE PENTENE NITRILE ISOMERS TO BE SEPARATED.
