SEPARATION OF N,N,N'-TRIMETHYLBISAMINO- ETHYLETHER FROM MIXTURES COMPRISING TERTIARY AMINES OR TERTIARY AMINOALKYLETHERS

摘要

The present invention relates to a method for recovering N,N,N′-trimethylbisaminoethylether from a mixture with its amide and a method for separating N,N,N′-trimethylbisaminoethylether from mixtures comprising tertiary amines or tertiary aminoalkylether as well as a composition comprising a mixture of N,N,N′-trimethylbisaminoethylether and a transamidation agent.
