Abstract : This invention relates to a novel halogen-substituted diphospha-s-triazines and to a method for their synthesis. In a more specific manner, this invention relates to a method for synthesizing halogen-substituted diphospha-s-triazines by effecting a reaction between an imidodiaryl-diphosphonic acid pentahalide and a perfluoroalkyl or a perfluoroalkylether amidine, and to the novel diphospha-s-triazine compounds produced thereby. The compounds of this invention and their thio and azido substituted triazine derivatives find application as antioxidant and anticorrosion additives for perfluorinated lubricating fluids and greases. The present interest in the utilization of perfluoroalkylether type fluids for wide temperature range lubricating applications has created a need for effective antioxidant and anticorrosive additives in order to permit their functioning in the presence of metals and alloys at elevated temperatures. In addition to their use as antioxidants, the halogenated diphospha-s-triazines of this invention can be substituted by a variety of groups thus provide a series of novel compounds to be utilized as monomers in polymer formation.
