DEVELOPMENT OF NONFLAMMABLE HYDRAULIC FLUIDS AND LUBRICANTS

The addition of ethylene oxide or glycidol to tetrameric bis (p-hydroxyphenoxy) phosphonitrile resulted in the formation of water-soluble fluid products. The synthetic method for tetrameric bis (p-nitrophenoxy) phosphonitrile an intermediate for water-soluble products -, an improved procedure fot the chloromethylation of trimeric bis (phenoxy)-phosphonitrile, and a method for converting the chloromethylated product to the corresponding hydroxymethyl compound were developed. Trimeric N-methylm-chloroanilino-2, 2, 2-trifluoroethoxy-phosphonitrile was prepared. This compound had a spontaneous ignition temperature slightly higher than trimeric N-methyl anilino-2, 2, 2-trifluoroethoxy-phosphonitrile. Utilization of a trimer-tetramer phosphonitrilic chloride mixture in place of the pure compounds for the synthesis of substituted aryloxy-2, 2, 2-trifluoroethoxy phosphonitriles was investigated and found to be feasible.
