A new type of water-soluble phosphonitrilate for potential use as water-base hydraulic fluid was synthesized by the reaction of trimeric bis p-hydroxyphenyl phosphonitrilate with ethylene oxide. Trimeric and tetrameric bis p-nitrophenyl phosphonitrilate, a trimeric bis m-nitrophenyl-2, 2, 2-trifluoroethyl phosphonitrilate, and tetrameric bisp-hydroxyphenyl phosphonitrilate were synthesized as intermediates to be used in the preparation of potential water-base hydraulic fluids. Hexakis 3-pyridinyl triphosphonitrilate was synthesized and found to be water insoluble. The chloromethylation of hexaphenyl triphosphonitrilate was effected employing chloromethyl methyl ether as chloromethylating agent. Several new arylamino-polyfluoroalkoxy phosphonitriles were isolated and characterized. Two trimeric and two tetrameric mixed substituted aryl-polyfluoro alkyl phosphonitrilates performed very satisfactorily in Falex wear tests. Author
