Definitions

  • the present invention relates to lubricant compositions which are particularly suitable for the lubrication of turbines or (turbo) compressors, which serve for the compression of chlorine and / or chlorine-containing products.
  • Lubricating oils for turbines and compressors are known from the prior art.
  • WO 201 1/070141 describes a lubricating oil composition which contains, in addition to a base oil, a succinic acid derivative and an epoxy compound as additives.
  • WO 2008/074760 also describes lubricating oil compositions known as
  • Additives contain an aspartic acid derivative and an epoxy compound or a fatty acid ester of a polyhydric alcohol.
  • Lubricants for turbocompressors or turbines which serve for the compression of chlorine or chlorine-containing products, are known. These lubricants usually comprise a highly refined base oil mixture, an additive combination for rust and oxidation inhibition and optionally defoamers.
  • EP extreme pressure / high pressure
  • lubricants from the prior art have the disadvantage of low resistance to chlorine or chlorine-containing products and cause corrosion of metals that come into contact with the chlorine-containing lubricants.
  • the lubricants of the prior art have a resistance to chlorine of up to at most 50 ppm in the oil. However, this is insufficient because chlorine dissolves in significantly higher quantities in lubricating oils.
  • the present invention is therefore based on the object to provide a lubricant composition which has improved resistance to chlorine and chlorine-containing products and should not cause corrosion.
  • a lubricant composition comprising a base oil, a hydrolysis protection component and a rust and oxidation inhibitor.
  • the present invention therefore relates to lubricant compositions comprising a) a base oil having a viscosity of 30 to 70 mm 2 / s at 40 ° C, b) a hydrolysis protective component comprising at least one C 2 -C 22 -fatty acid C 1 -C 12 -alkyl ester and / or epoxidized at least one epoxidized C 11 -C 22 fatty acid glyceride, having an epoxide oxygen content of 1 to 10 wt .-%, based on the total mass of epoxidized fatty acid Ci-Ci2-alkyl ester and / or epoxidized fatty acid glyceride, and c) a rust and oxidation inhibitor selected under at least one single or multiple Ci-Ci2-alkyl-substituted phenol, at least one aryl amine and at least one mono- or polysubstituted triazole and mixtures of two or more of these components.
  • the viscosity of the hydrocracking oil is to be understood as meaning the kinematic viscosity, which is determined with a Stabinger Viscometer SVM 3000, Anton Paar GmbH, at 40 ° C.
  • Epoxy oxygen content means the percentage by weight of oxygen, based on the total mass of epoxidized compounds.
