  • Publication number: 20070254821
    Abstract: Molybdenum-free lubricating compositions are provided, having an antioxidation additive composition based on a combination of (1) alkylated diphenylamine (APDA), (2) polyamine dispersant, and (3) monoglyceride, ethoxylated amide, or mixtures thereof. Further synergy is achieved when component (3) is borated, allowing a reduction in phosphorus levels to below 0.08% or even a phosphorus-free composition.

  • Publication number: 20060199745
    Abstract: Thie invention relates to a novel asymmetrical, secondary dialkylamine-based molybdenum dithiocarbamate with improved friction reducing performance, viscosity and solubility, and lubricating compositions containing the same. The compounds are produced from asymmetrical dialkylamine of the formula R1-NH-R2 where R1 and R2 are different, and are independently selected from alkyl groups C3 to C19. In a preferred embodiment, R3 and R4 are different and are independently selected from alkyl groups C3 to C19.

  • Publication number: 20060183648
    Abstract: Antimony dithiocarbamate is known to provide extreme pressure (EP) protection in lubricating compositions, such as grease. However, there is a desire to reduce the amount of antimony used in such compositions, while still maintaining acceptable EP performance. It has now been found by using small amounts of either ammonium dithiocarbamate or zinc dithiocarbamate in combination with the antimony dithiocarbamate (SbDTC), a lower amount of SbDTC can be used in the lubricating composition while still maintaining excellent or exceptional EP protection. To counteract the corrosive effects of the SbDTC and ammonium dithiocarbamate composition, it has been found that compounds containing a carboxylic acid group are effective in avoiding copper corrosion.

  • Publication number: 20060035791
    Abstract: A lubrication composition providing excellent anti-wear protection for corrosion-resistant materials which comprises a major amount of a synthetic ester base oil, and a minor amount of a molybdenum compound and an anti-wear additive selected from the group consisting of 1,3,4-thiadiazole derivative as an anti-wear additive, the reaction products of 2,5-dimercapto-1,3,4-thiadiazole dimers and poly(ether)glycols, and 2,5-dimercapto-1,3,4-thiadiazole monomer and mixtures thereof. Also described is a method for imparting anti-wear properties to a corrosion resistant material, comprising using the lubricating composition of the invention.
