ABSTRACT:
Hydrolytically and thermooxidatively stable monophospha-s-triazines prepared by reaction of octafluoroisobutylene epoxide with an acid fluoride followed by transformation of the resultant product into an amide, then into a nitrile, reacting the nitrile with ammonia and reacting the imidoylamidine resulting from the previous steps with di-aryltrihalophosphorane to produce mono-phospha-s-triazines that are useful as antioxidant - anticorrosion agents for perfluoroalkylether fluids are disclosed.
