DEVELOPMENT OF NONFLAMMABLE HYDRAULIC FLUIDS AND LUBRICANTS

Additional trimeric and tetrameric mixed substituted (aryl-1, 1-di H-polyfluoroalkyl)phosphonitrilates were prepared and evaluated. Of these, trimeric (m-ethylphenyl-1, 1-di H-trifluoroethyl) phosphonitrilate had the lowest density (1.33) and tetrameric (m-fluorophenyl-1, 1-di H-heptafluorobutyl) ph...

Zusammenfassung:Additional trimeric and tetrameric mixed substituted (aryl-1, 1-di H-polyfluoroalkyl)phosphonitrilates were prepared and evaluated. Of these, trimeric (m-ethylphenyl-1, 1-di H-trifluoroethyl) phosphonitrilate had the lowest density (1.33) and tetrameric (m-fluorophenyl-1, 1-di H-heptafluorobutyl) phosphonitrilate, the lowest pour point (-45 F) obtained so far in this class of compounds. Trimeric bis(p-methoxyphenyl) phosphonitrilate have been prepared as intermediates for potentially water soluble or emulsifiable products. Two members of a new class of fluids, the trimeric and tetrameric mixed substituted (arylamino-polyfluoroalkoxy) phosphonitriles have been prepared and evaluated. (Author)
