Abstract
The present invention is related to a series of derivatives of novel ether diamine compounds prepared by the cynobutylation reaction of an alcohol having 3 to 22 carbon atoms with 2-pentenenitrile to form a branched alkyl ether nitrile. The etheraminonitriles formed by the process are hydrogenated to form alkylether amines. The resulting product can be reacted with 2-pentenenitrile and or acrylonitrile and in 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 diamines 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 disclosed novel amine oxides, and quaternary compounds made from said tertiary amines.
