N and one, from a mixture comprising a dialkyl N- bis-aminoalkyl ether, N, at least N, N, N N'- and bis-trialkyl amino alkyl ethers, N, N ', of N'- tetraalkyl bis aminoalkyl ether , a method for separating the N- dialkyl bisamino alkyl ether

摘要

In accordance with the present invention, N is a primary amine, a bis-dialkylamino N- amino alkyl ethers, N, N is a tertiary amine N, N, a-bis N'- trialkyl amino alkyl ether is a secondary amine, from a mixture comprising the one, N is a primary amine, a method for separating N- dialkyl bis-aminoalkyl ether by receiving at least N ', the N'- tetraalkyl bis aminoalkyl ethers, the method of separation, by mixing the mixture with at least one aldehyde, reacting a primary amine said at least either the aldehyde and ketone, imine primary amine base is prepared by Schiff base reaction by AND (α) ketone It is; by hydrolysis of (γ) first amine-based and imine, first from the first amine-based imine; process to separate the imine of the first amine base from at least one said of a tertiary amine or secondary amine (β) I include; recovering the amine.
