From a mixture comprising N, N-dialkylbisaminoalkylether and at least one of N, N, N'-trialkylbisaminoalkylether and N, N, N ', N'-tetraalkylbisaminoalkylether Method for separating N, N-dialkylbisaminoalkyl ether |
| abstract |
The present invention (α) the secondary amine, which is the primary amine, and the N, N, N'-trialkylbisaminoalkyl ether, for reacting a primary amine, which is N, N-dialkylbisaminoalkylether, with at least one of a ketone and an aldehyde A mixture comprising an amine and at least one of a tertiary amine, which is N, N, N ', N'-tetraalkylbisaminoalkylether, is combined with at least one of a ketone and an aldehyde to provide a primary amine based imine by Schiff base reaction. Steps, (β) separating the primary amine based imine from at least one of a secondary amine or a tertiary amine; And (γ) recovering the primary amine from its primary amine imine by hydrolysis of the primary amine imine A primary amine, and a method for separating primary amines from a mixture comprising at least one of secondary and tertiary amines. |
