ABSTRACT:
Residual amounts of water and color-causing impurities can be removed from a 2-oxazoline compound by introducing from 0.01 to 25 weight percent of a dialkyl hydrogen phosphite or a halosilane compound to the 2-oxazoline and then distilling the oxazoline. For example, 0.5 weight percent of bis(2-ethylhexyl)hydrogen phosphite was introduced into 100 grams of 2-ethyl-2-oxazoline containing 1000 parts per million (ppm) of water and the mixture was then distilled to yield 2-ethyl-2-oxazoline containing less than 10 ppm of water.
