ABSTRACT:
Disclosed is a high yield process for quaternizing imidazoline ester compounds in the absence of lower alcohol solvents and under anhydrous conditions. The reaction product of this process contains a quaternized imidazoline ester fabric softening compound and, optionally, an imidazoline ester compound. In the process of this invention, an imidazoline ester compound is intitially heated to form an anhydrous melt. This anhydrous melt is subsequently contacted with a quaternizing agent selected from small chain organic halides and sulfates. The imidazoline ester compound and quaterinzing agent are then reacted under anhydrous conditions for a period of time sufficient for substantially all of said quaterinzing agent to react with said imidazoline ester compound to form a quaternized imidazoline ester compound.
