Definitions

  • the present invention relates to a method of improving the stability of a detergent in a lubricating oil composition, or a method of improving the compatibility of a detergent with other additives in a lubricating oil composition, such as friction modifiers, other detergents, metal rust inhibitors, viscosity index improvers, corrosion inhibitors, oxidation inhibitors and anti-wear agents.
  • the invention relates to a method of improving the compatibility of a detergent with friction modifiers or other detergents present in a lubricating oil composition.
  • a method of improving the stability of a detergent in a lubricating oil composition or a method of improving the compatibility of a detergent with another additive in a lubricating oil composition including the step of reacting the detergent with a water-soluble ⁇ , ⁇ -unsaturated carbonyl compound.
  • the water-soluble ⁇ , ⁇ -unsaturated carbonyl compound is preferably selected from maleic anhydride, itaconic anhydride, citriconic anhydride, alkyl maleic anhydride, cycloalkyl maleic anhydride, acrylic acid and methacrylic acid.
  • the water-soluble ⁇ , ⁇ -unsaturated carbonyl compound is preferably maleic anhydride.
  • the detergent is reacted with from about 0.5 to about 10, preferably from about 1 to about 6, more preferably from about 2 to about 5 wt. %, e.g., 2 to 4 wt. %, of the water-soluble ⁇ , ⁇ -unsaturated carbonyl compound, based on the weight of detergent.
  • the reaction can be carried out at temperatures of from about 30°C to about 200°C, preferably from about 60°C to about 150°C, more preferably from about 80°C to about 120°C, for about 0.5 hours to about 8 hours.
  • additives found in lubricating oil compositions are metal rust inhibitors, viscosity index improvers, corrosion inhibitors, oxidation inhibitors, antifoaming agents, anti-wear agents and pour point depressants. Some are discussed in further detail below.
  • a dithiophosphoric acid may be made by reacting mixtures of primary and secondary alcohols.
  • multiple dithiophosphoric acids can be prepared where the hydrocarbyl groups on one are entirely secondary in character and the hydrocarbyl groups on the others are entirely primary in character.
  • any basic or neutral zinc compound could be used but the oxides, hydroxides and carbonates are most generally employed.
  • Commercial additives frequently contain an excess of zinc due to the use of an excess of the basic zinc compound in the neutralization reaction.
  • the preferred zinc dihydrocarbyl dithiophosphates are oil soluble salts of dihydrocarbyl dithiophosphoric acids and may be represented by the following formula: wherein R and R' may be the same or different hydrocarbyl radicals containing from 1 to 18, preferably 2 to 12, carbon atoms and including radicals such as alkyl, alkenyl, aryl, arylalkyl, alkaryl and cycloaliphatic radicals. Particularly preferred as R and R' groups are alkyl groups of 2 to 8 carbon atoms.
  • Typical oil soluble aromatic amines having at least two aromatic groups attached directly to one amine nitrogen contain from 6 to 16 carbon atoms.
  • the amines may contain more than two aromatic groups.
  • Compounds having a total of at least three aromatic groups in which two aromatic groups are linked by a covalent bond or by an atom or group (e.g., an oxygen or sulphur atom, or a -CO-, -SO 2 - or alkylene group) and two are directly attached to one amine nitrogen also considered aromatic amines having at least two aromatic groups attached directly to the nitrogen.
  • a viscosity index improver dispersant functions both as a viscosity index improver and as a dispersant.
  • examples of viscosity index improver dispersants include reaction products of amines, for example polyamines, with a hydrocarbyl-substituted mono -or dicarboxylic acid in which the hydrocarbyl substituent comprises a chain of sufficient length to impart viscosity index improving properties to the compounds.
  • additives which maintains the stability of the viscosity of the blend may be necessary to include an additive which maintains the stability of the viscosity of the blend.
  • polar group-containing additives achieve a suitably low viscosity in the pre-blending stage it has been observed that some compositions increase in viscosity when stored for prolonged periods.
  • Additives which are effective in controlling this viscosity increase include the long chain hydrocarbons functionalized by reaction with mono- or dicarboxylic acids or anhydrides which are used in the preparation of the ashless dispersants as hereinbefore disclosed.
