Abstract
The present invention relates to a series of derivatives of novel ether amine compounds prepared by the cyanobutylation reaction of an alcohol having 3 to 22 carbon atoms with 2-pentenenitrile to form a branched alkyl ether nitrile. The alkyl ether nitrites formed by the process are hydrogenated to form alkylether amines. The resulting product can be reacted with 2-pentenenitrile and or acrylonitrile and in a subsequent step, hydrogenated to yield a diamine. Specifically, the present invention deals with two types of tertiary amines one made by the reaction of novel ether amine compounds with ethylene oxide, propylene oxide or butylene oxide or mixtures thereof producing alkoxylated tertiary amines and the other made by the reaction of novel ether amine compounds with formaldehyde and hydrogen producing methylated tertiary amines. The invention also discloses novel amine oxides, and quaternary compounds made from said tertiary amines.
