摘要：
According to the present invention, a method for separating a primary amine being an N,N- dialkylbisaminoalkylether, from mixtures comprising said primary amine and at least one of a secondary amine being an N,N,N'-trialkylbisaminoalkylether and a tertiary amine being an N,N,N',N'-tetraalkylbisaminoalkylether, comprising the steps: (α) joining said mixture and at least one of a ketone and an aldehyde for reacting said primary amine with said at least one of a ketone and an aldehyde, thereby providing a primary amine based imine by a Schiff base reaction; (β) separating the primary amine based imine from said at least one of the secondary or tertiary amine; and (γ) recovering the primary amine from its primary amine based imine by hydrolysis of the primary amine based imine.
