    摘要: A process for manufacturing hydroxyalkyl bis(dialkylaminoalkyl)amine is disclosed wherein dialkylaminopropylaminopropionitrile is separated from a mixture of dialkylaminopropylaminopropionitrile and bis(dialkylaminoalkyl)amine by adding to the mixture under alkoxylation conditions alkylene oxide sufficient to react with substantially all of the bis(alkylaminoalkyl)amine and then separating the reacted materials by distillation. This process yields very pure hydroxyalkyl bis(dialkylaminoalkyl)amine which is useful as a urethane catalyst.
