Title:
A separation method of N [from a mixture], N, and N'- Trimethyl screw aminoethyl ether and/or N, and N- Dimethyl screw aminoethyl ether
Document Type and Number:
Japanese Patent JP6266098
Kind Code:
B2
Abstract:
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.
