METHOD FOR SEPARATING PENTENENITRILE ISOMERS |
摘要 |
The invention relates to a method for separating pentenenitrile isomers havi ng a relative volatility alpha in the region 1.0 - 1.3 in a pressure range of 1 - 500 kPa by means of separation. According to said method, the distillation i s carried out in the presence of a liquid diluent which forms azeotropes with the pentenenitrile isomers in the same pressure conditions, whose relative volatility alpha is higher than the pentenenitrile isomers which are to be separated.
