ABSTRACT:
A 2-oxazoline is separated from an aqueous solution by contacting this solution with a membrane selectively permeable to the 2-oxazoline, removing the 2-oxazoline as a vapor on the other side of the membrane and recovering it by cooling. Polyethylene hollow fibers are particularly desirable membranes, which purify the 2-oxazoline as it is separated from the water.
