Abstract : This invention relates in general to novel halogen substituted monophospha-s-triazine compounds and to a method for their synthesis. In a more particular manner, this invention concerns itself with a method for synthesizing halo-substituted monophospha-s-triazines by effecting a reaction between a phosphorus pentahalide and a perfluoroalkyl or a perfluoroalkylether imidoylamidine and to novel triazine compounds produced thereby. The novel compounds of this invention, namely the holo-substituted monophospha-s-triazines, are best represented by 1-dichlorophospha-3,5-bis(perfluoroalkylether)-2,4,6-trizine, as well as their thio and azido derivatives. The holo-substituted monophospha-s-triazines provide a hydrogen-free system amenable for use as antioxidation and anticorrosion additives for perfluorinated lubricating fluids and greases. They are useful also as monomers for incorporation into polymers, the latter due to the presence of two replaceable hologens. The present interest in the utilization of perfluoroalkylether type fluids for wide termperature range lubricating applications has created a need for effective antioxidant and anticorrosive additives to permit their functioning in the presence of matals and alloys at elevated temperatures.
