Abstract:
A number of mixed substituted trimeric and tetrameric arylamino-polyfluoroalkoxy phosphonitriles were prepared. A typical representative of this new class of compounds, bisN-methylanilino-hexakis1,1-di H-trifluoroethoxy phosphonitrile, passed the hydrolytic stability test of specification MIL-H-19457A and gave also excellent results in the Falex wear test. Another representative, bisN-methylanilino- tetrakis 1,1-di H-trifluoroethoxy phosphonitrile, gave viscosities approaching those of the same specification. Catalytic reduction of trimeric bisp-nitrophenyl phosphonitrilate afforded bisp-aminophenyl phosphonitrilate in excellent yield. Ethoxylation of the latter resulted in the consumption of 10.8 moles of ethylene oxide per amino-group to give a water soluble material having potential for use in water base hydraulic fluids. Representatives of the novel class of arylthio-polyfluoroalkoxy phosphonitriles were synthesized but were found to display slow hydrolytic instability and poor lubricity. Author
