    Abstract: Polyurethanes made using compounds of formula A: Q-(R6)-M-(R7)-NR3R4 where Q is OH or NR1R2; M is O or NR5 where R5 is R1 or H; R1 is alkyl or an alkylene alcohol of from 1 to 6 carbons, especially CH3, CH2CH3, or CH2CH2OH; R2 is alkyl or an alkylene alcohol of from 1 to 6 carbons, especially CH3, CH2CH3, or —CH2CH2OH; R3 is hydrogen or alkyl of from 1 to 6 carbons, especially H, CH3 or CH2CH3; R4 is hydrogen; where R6 is an alkylene group of from 2 to 5 carbons; and wherein R7 is an alkylene group of from 2 to 5 carbons. Illustrative catalysts of this invention include but are not limited to N,N,N′-trimethylbis(aminoethyl)ether, dimethylaminoethoxypropylamine, and (3-aminopropyl)(2-hydroxyethyl)methylamine.

    Abstract: A process for the separation of a first amine having a tertiary amine group and a secondary amine group such as N,N,N′-trimethylbis(aminoethyl)ether from a di-tertiary amine such as N,N,N′,N′-tetramethylbis(aminoethyl)ether, comprising: contacting a mixture of the first amine and the di-tertiary amine with a carbonyl compound capable of forming an enamine such that the carbonyl compound reacts with the first amine to form an enamine; separating the enamine from the di-tertiary amine; and subsequently converting the enamine to the first amine.
