Definitions

  • Esters useful as synthetic oils also include those made from C 5 to C 12 monocarboxylic acids and polyols, and polyol ethers such as neopentyl glycol, trimethylolpropane, pentaerythritol, dipentaerythritol and tripentaerythritol.
  • Unrefined, refined and re-refined oils can be used in the compositions of the present invention.
  • Unrefined oils are those obtained directly from a natural or synthetic source without further purification treatment.
  • a shale oil obtained directly from retorting operations a petroleum oil obtained directly from distillation or ester oil obtained directly from an esterification process and used without further treatment would be unrefined oil.
  • Refined oils are similar to the unrefined oils except they have been further treated in one or more purification steps to improve one or more properties. Many such purification techniques, such as distillation, solvent extraction, acid or base extraction, filtration and percolation are known to those skilled in the art.
  • Organo-molybdenum compounds such as dinuclear or trinuclear molybdenum compounds, are preferred where an inorganic friction modifier is to be provided, and may be present at a concentration in the range 0.1 to 2 mass %, or providing at least 10 such as 50 to 2,000 ppm by mass of molybdenum atoms.
  • Dispersants are usually "ashless", as mentioned above, being non-metallic organic materials that form substantially no ash on combustion, in contrast to metal-containing, and hence ash-forming materials. They comprise a long hydrocarbon chain with a polar head, the polarity being derived from inclusion of e.g. an O, P, or N atom.
  • the hydrocarbon is an oleophilic group that confers oil-solubility, having, for example 40 to 500 carbon atoms.
  • ashless dispersants may comprise an oil-soluble polymeric backbone.
  • Anti-oxidants are sometimes referred to as oxidation inhibitors; they increase the resistance of the composition to oxidation and may work by combining with and modifying peroxides to render them harmless, by decomposing peroxides, or by rendering an oxidation catalyst inert. Oxidative deterioration can be evidenced by sludge in the lubricant, varnish-like deposits on the metal surfaces, and by viscosity growth.
  • Rust and corrosion inhibitors serve to protect surfaces against rust and/or corrosion.
  • rust inhibitors there may be mentioned non-ionic polyoxyalkylene polyols and esters thereof, polyoxyalkylene phenols, and anionic alkyl sulfonic acids.
