    摘要: The invention relates to a method for separating by distillation all or part of an imine (III) from a mixture (II) containing an amine (I) and an imine (III). Said method is characterized in that a compound (IV) which under distillation conditions is inert in relation to the amine (I) and whose boiling point under distillation conditions lies above the boiling point of the amine, is added to the distillation mixture, and that distillation yields a mixture (VI) which essentially contains a compound (IV).
