Definitions

  • the present invention relates to oil-based lubricant compositions comprising esters of aromatic polycarboxylic acids.
  • Oil-based lubricants conventionally contain a mineral oil, a hydrocarbon polymer e.g. a polybutene and an organic ester as the main components.
  • the esters are added to the lubricants to improve their performance in specific applications.
  • the choice of ester used is limited by several factors such as viscosity index, compatibility with hydrocarbon base oil components (e.g. polybutenes), volatility and oxidative stability.
  • One type of ester which meets most of these criteria is that derived from trimellitic acid and linear primary alcohols.
  • a specific example is an ester derived from trimellitic acid and a mixture of linear Cg and C 10 primary alcohols.
  • trimellitates of linear primary alcohols suffer from some disadvantages under low temperature conditions. For instance, such trimellitates have unacceptable low temperature compatibility with the hydrocarbon base oil components in the lubricant. More importantly, lubricants containing trimellitates of linear primary alcohols solidify on standing at low temperatures, e.g. around -10°C. These disadvantages are significant if the lubricants are to be used in cold environments especially if used as crank case lubricants in automotive engines.
  • the present invention is a lubricant composition
  • a lubricant composition comprising a mineral oil, a hydrocarbon base oil component and a trimellitate ester component characterised in that the ester component is either a mixture of a trimellitate ester of a branched chain alcohol and a trimellitate ester of a linear alcohol, or a trimellitate ester derived from a mixture of linear and branched chain alcohols.
  • the hydrocarbon base oil component referred to herein is preferably a hydrocarbon polymer, most preferably a polybutene.
  • the weight average molecular weight of the polybutene used is suitably from 200 to 6000, preferably from 1000 to 3000.
  • trimellitate esters are suitably those of linear and branched chain primary alcohols and are preferably derived by reacting trimellitic acid or the anhydride thereof with one or more of the appropriate primary alcohols having 8 to 10 carbon atoms.
  • trimellitate ester component is more preferably derived by the reaction of trimellitic anhydride with a mixture of the relevant linear and branched primary alcohols. Trimellitate esters which are derived from mixtures of isodecanol and C S -C 10 linear alcohols are particularly preferred.
  • the relative amounts of the trimellitate esters derived from linear and branched chain primary alcohols will depend upon the intended use of the lubricant composition. However, for lubricants usable in low temperature environments, the relative proportions of linear trimellitate esters to branched chain trimellitate esters is suitably from 4:1 to 1:4, preferably from 2:1 to 1:2 by weight.
  • the lubricant composition may contain other conventional additives such as antioxidants, detergents, stabilizers and the like.
  • trimellitate esters were prepared from trimellitic anhydride and the respective alcohol using a round-bottom two litre flask fitted with anchor stirrer, thermometer pocket, nitrogen sparge and Dean and Stark head/condenser. All products were prepared using conventional stannous oxalate catalysts, at a maximum reaction temperature of 210°C using conventional techniques.
  • the alkyl group composition of esters prepared is detailed in Table 1.
  • the mixed trimellitate of linear C 8 /C 10 alcohol and isodecanol was found to offer both a much reduced viscosity ratio compared to a mixed tri(isodecyl/tridecyl) trimellitate and an acceptable low temperature hydrocarbon compatability.
