Abstract:
A process for making a tertiary amine ester of the following formula (I): ##STR45##the process comprising:(a) reacting a ketone or an aldehyde having the formula ##STR46##with a glycol to form a ketal or an acetal;(b) reacting the ketal or the acetal with acrylonitrile to form an ether nitrile;(c) reducing the ether nitrile to a tertiary amine ketal or a tertiary amine acetal;(d) hydrolyzing the tertiary amine ketal or the tertiary amine acetal to a tertiary amine diol; and(e) esterifying the tertiary amine diol to the tertiary amine ester of formula (I), wherein R.sup.1 and R.sup.2 are each independently a hydrogen atom or a linear, branched, or cyclic alkyl, alkylene, alkaryl, or aryl-containing group containing 1 to 18 carbon atoms; andeach R.sup.3 are each independently of one another fatty acid radicals having 6-22 carbon atoms.
