Definitions

  • This invention relates to lubricants and has specific reference to lubricants intended for mechanisms wherein the prevailing temperature and pressure conditions are such that it is not possible to have an oil film maintained by hydrodynamic forces between the rubbing metal surfaces, and for which the oiliness, that is, the aptitude of a lubricant to adhere to the metal without corrosion, under moderate pressures is preserved when the temperature attains values considerably higher than those which could not safely be overstepped heretofore with hitherto known products, these lubricants providing the desired seizureresisting characteristic under very high pressures at which the oiliness is no more available.
  • methyl or ethyl pentachlorobutyrates are obtained, as already known, by esterifying directly the pentachlorobutyric acid with methyl or ethyl alcohol saturated with hydrochloric gas.
  • This invention is concerned with a new lubricant composition which is obtained by adding to known lubricating oils quantities ranging from .2% to 3.0% of the methyl or ethyl ester of a pentachlon'nated butyric acid, which constituted the subject-matter of former researches by the applicant, and wherein the position of the chlorine atoms corresponds to the following formula:
  • mixture 2 is characterized by a complete absence of corrosiveness even under very severe conditions of operation.
  • the new lubricants are particularly useful for lubricating internal combustion engines during the running-in period, and also for the permanent lubrication of transmission members, gearbox pinions, bevel gears, etc. inasmuch as the risk of corrosion is extremely low with these lubricants.
  • a lubricant eifective to maintain between two sliding surfaces the necessary lubricating film under pressure and temperature conditions wherein the maintainance of this film is not ensured by hydrodynamic forces, and effective to provide resistance to seizure under very high pressures and very high corrosion-resisting properties with respect to metal said lubricant comprising a major proportion of mineral oil, 0.2 to 3% by weight of at least one compound selected from the group consisting of the methyl and ethyl esters of pentachlorobutyric acid of the formula Cl CCI-IClCI-IClC0OH, and 0.05 to 2% by weight of at least one long-chain fatty compound selected from the group consisting of long-chain fatty acids and the methyl, ethyl, propyl and isopropyl esters thereof.
  • a lubricant effective to maintain between two sliding surfaces the necessary lubricating film under pressure and temperature conditions wherein the maintainance of this film is not ensured by hydrodynamic forces, and effective to provide resistance to seizure under very high pressures and very high corrosion-resisting properties with respect to metal, said lubricant comprising a major proportion of mineral oil, 0.2 to 3% by weight of at least one compound selected from the group consisting of the methyl and ethyl esters of pentachlorobutyric acid of the formula Cl C CHCl-CHCl-COOH, and 0.05 to 2% by weight of at least one long-chain fatty compound selected from the group consisting of palmitic acid, stearic acid, behenic acid, and the methyl, ethyl, propyl and isopropyl esters thereof.
