Method for separating N, N-dialkylbisaminoalkyl ether from mixtures comprising N, N-dialkylbisaminoalkyl ether and at least one of N, N, N'-trialkylbisaminoalkyl ether and N, N, N ', N'-tetraalkylaminoalkyl ether |
abstract |
Method for separating a primary amine that is a N, N-dialkylbisaminoalkyl ether, from mixtures comprising said primary amine and at least one of a secondary amine that is a N, N, N'-trialkylbisaminoalkyl ether and a tertiary amine that is an N, N, N ', N'-tetraalkylbisaminoalkyl ether, the method comprising the steps of: (α) bringing said mixture and at least one of a ketone and an aldehyde to react said primary amine with said at least one of a ketone and an aldehyde , thereby providing a primary amine-based imine via a Schiff base reaction; (β) separating the primary amine-based imine from said at least one of the secondary or tertiary amine by distillation; and (γ) recovering the primary amine from its primary amine-based imine by hydrolysis of the primary amine-based imine. |
