Process for distillation separation of pentenenitrile isomers, which have a relative relative volatility in the pressure range of 1 to 500 kPa in the range of 1.0 to 1.3, characterized in that the distillation is carried out in the presence of a liquid diluent, which, under the same pressure conditions, forms azeotropes with the pentenenitrile isomers, whose relative volatility alpha is higher than that of the pentenonitrile isomers to be separated. |
