Method for separating N,N,N'-trimethylbisaminoethylether and/or N,N-dimethylbisaminoethylether from a mixture
-
Paragraph 0138, (2015/05/05)
The present invention relates to a method for separating N,N,N'-trimethylbisaminoethylether and/or N,N-dimethylbisaminoethylether, from a mixture A comprising N,N,N'-trimethylbisaminoethylether, and N,N-dimethylbisaminoethylether, wherein said method comprises the steps of: (a) contacting said mixture A with an acylating agent, to form a mixture B comprising the amides of N,N,N'-trimethylbisaminoethylether and of N,N-dimethylbisaminoethylether, respectively; and (b1) separating the amide of N,N,N'-trimethylbisaminoethylether from mixture B; and (c1) recovering N,N,N'-trimethylbisaminoethylether from its amide by means of a transamidation reaction; and/or (b2) separating the amide of N,N-dimethylbisaminoethylether from mixture B; and (c2) recovering N,N-dimethylbisaminoethylether from its amide by means of a transamidation reaction.
