摘要:
A process for making a tertiary amine ester of formula (I), the process comprising: (a) reacting a ketone or an aldehyde having formula (III) 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 nitril 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 and R 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; and each R are each independently of one another fatty acid radicals having 6-22 carbon atoms. The process may optionally include the further step of: (f) protonating or quaternizing the tertiary amine ester of formula (I) to a protonated or quaternary amine ester of formula (II) wherein A is an inorganic or organic anion.
