Method for separating 6-aminocaproic acid nitrile from mixtures containing 6-aminocaproic acid nitrile and an imine |
| abstract |
The invention relates to a method for separating by distillation 6-aminocaproic acid nitrile from mixtures (I) containing 6-aminocaproic acid nitrile and an imine (II). Said method is characterized in that distillation takes place in a distillation column and that the distillation mixture remains on at least one level of the distillation column for an average period of at least 5 minutes. |
