Definitions

  • the present invention relates to oils having improved oxidation stability containing fatty acid esters and alkylphenol resins,
  • Oils obtained from animal or vegetable material are principally fabric invertebrates comprising triglycerides of monocarboxylic acids, e.g. As acids having 10 to 25 carbon atoms, and the formula in which R is an aliphatic radical of 10 to 25 carbon atoms, which may be saturated or unsaturated.
  • oils contain glycerides of a number of acids, the number and variety of which varies with the source of the oil, and they may additionally
  • oils Contain phosphoglycerides. Such oils can be obtained by methods known in the art.
  • fatty acid alkyl esters are also used as additives for, for example, mineral oils and mineral oil distillates.
  • fuel oils with a sulfur content reduced to less than 500 ppm have such poor friction and wear-reducing properties that so-called lubricity additives must be added to them.
  • lubricity additives are based inter alia on esters of unsaturated fatty acids with lower alcohols (biodiesel).
  • the oily fluids used as fuel oils and additives are mainly based on oils from natural sources such as oilseed rape, sunflowers, soya and similar oilseeds. These have a high content of unsaturated fatty acids of more than 50%, and preferably of more than 80%, which gives them acceptable rheological properties, especially in the cold.
  • EP-A-0635558 the use of biodiesel based on C 1 -C 5 -alkyl esters of saturated and unsaturated, straight-chain C 12 -C 22 fatty acids as lubricity improvers for gas oils with low sulfur and aromatic content.

  • the hydroxybenzenes improve, inter alia, the oxidation stability of the additives.
  • the oily liquids based on esters of unsaturated fatty acids which are preferred because of their rheological properties over the esters based on saturated fatty acids, can, on prolonged storage, especially at elevated temperature, harden to only partially oil-soluble products. This can lead to the formation of viscous precipitates and deposits in the storage container as well as in the additized fuel oil. Even in the engine, this can lead to deposits, in particular at the valves and injection nozzles.
