Definitions

  • This invention relates to a novel substituted diphenyl compound useful as a heatand oxidation-stable lubricant and to compositions containing the compound.
  • lubricants which are stable under the elevated temperatures of mllitary and commercial aircraft turbine engines.
  • One important class comprises diesters of alkane dioarboxylic acids; this type of compound is typified by d1-2- ethylhexyl sebacate.
  • the diesters are generally too volatile to be useful at temperatures above about 500 F. and begin to decompose at around 600 F.
  • This compound has the and has a molecular weight of 306 and a melting point of 505 1 C.
  • Inhibited Hercoflex 600 (mixed esters of pentearythritol) 19 o-(m-Phenoxy-phenoxy)diphenyl 122 Because of these desirable properties, the novel diphenyl described may readily be employed both as a lubricant and in admixture with other lubricants. For example, when it is added to another higher melting lubricant, the resulting mixture is characterized by a melting point considerably lower than that of the higher melting component.
  • diphenyl diphenyl oxides are those diphenyl oxides having a phenyl substituent on each of the phenyl rings att-ached to the oxyradical.
  • the preferred compositions are those wherein the o(m-phenoxy-phenoxy) diphenyl makes up at least about two-third of the total composition on a Weight basis.
  • Table III are presented the minimum melting points of binary systems containing the novel compound of the invention with the diphenyl oxides noted.
  • the melting points of the mixtures including the compound of the invention are considerably lower than that of the higher melting component and are about 10 C. lower than the melting point of the lower melting component.
