Definitions

  • This invention consists in improvements in the treatment of castor oiland related materials particularly to inhibit oxidation'and/ or drying, gumming or hardening of such materials.
  • the rate of oxidation of fatty oils depends on the types of fatty acids present and particularly on their degree of unsaturation.
  • the principal constituents of castor oil are the glycerides of ricinoleic acid, a hydroxy-substituted unsaturated fatty acid containing one ethylenic linkage.
  • the oxidation which takes place is almost certainly accompanied by a polymerisation process in which the unsaturated molecules take part.
  • the rate of oxidation and gum formation will, of course, depend on the temperature to which the oil is subjected and the presence of oxidation catalysts.
  • the invention relates not only to castor oil but to related materials such as the esters of ricinoleic acid, e. g., the simple esters of monohydric alcohols and the polyhydric alcohol esters, to lubricants consisting of mixtures of castor oil and mineral oil (comprising a major proportion of castor oil) and to the so-called casterbase greases containing a major proportion of castor oil.
  • the esters of ricinoleic acid e. g., the simple esters of monohydric alcohols and the polyhydric alcohol esters
  • lubricants consisting of mixtures of castor oil and mineral oil (comprising a major proportion of castor oil) and to the so-called casterbase greases containing a major proportion of castor oil.
  • This invention in its'broadest aspect therefore consists of a method of treating an oil of the kind described to inhibit oxidation and gumming which method consists in adding to the oil where R1, R3 and R4 are the same or difierent and are aromatic radicals, and R2 is a condensed aromatic nucleus having at least ten carbon atoms. Any or all of these radicals may be further substituted by alkyl, aryl, hydroxyl or amine groups, although the preferred substituents are hydrocarbon radicals only.

  • amines of the type described are. effective for the purpose, of the present invention, such closely related amines as aand p-naphthylamine.
  • the organic compounds of tin or antimony to be employed in conjunction with the amines already described are. derivatives, of. divalent (stannous) tin or of antimony and may be, the tin or antimony salts or soaps of organic carboxylic acids, organic sulphonic acids, organic dithiophosphoric acids, or the tin or antimony 7 derivatives of phenols, phenol thioethers, or mercaptans.

  • tin compounds do not themselves possess any appreciable antioxidant or gum-inhibiting properties, they cooperate with the aromatic amines of the type described to give inhibition of oxidation over a period of time considerably longer than could be obtained by the use of the amines themselves in comparable proportions.
  • the petroleum sulphonates of tin and antimony are particularly efiective.
  • the aromatic amines used in this invention may be employed in amounts ranging from about 0.1 to about 5.0 per cent and preferably between 0.5 and 2.0 per cent depending on the particular material to be inhibited, and the conditions under which it is to be employed While the tin or antimony compounds may be employed in amounts varying between about 0.05 and 2.0 per cent and preferably between 0.1 and 1.0 per cent. In general the best results are obtained when the amount of tin or antimony compound present does not exceed the amount of amine by weight and preferably the amount of amine employed is at least double the amount of tin or antimony compound.

  • Copper catalysts were cleaned with carborundum powder and washed in petroleum ether. Lead specimens were flattened, scraped with a special scraper and finally polished by brushing in one direction with file carding before washing in benzene and weighing. After a 2 hour period a further washing in benzene, brushing with a camel hair brush and reweighing was effected. The total corrosion was calculated by adding together the weight losses of the lead specimens after each two-hour period.
  • test-pieces rectangular plates of pure lead 1%" by 1" were mounted vertically just below the surface of the lubricant with the longer axis horizontal. Copper strips, as catalysts, wide and bent into a semicircle 3%" in diameter were placed wholly below the surface of the lubricant and attached by means of vertical copper wires to corks fitted in the beaker covers. Each beaker was also fitted with a thermometer.
