  • Patent number: 9109238
    Abstract: The present invention is generally directed to methods of making diester-based lubricant compositions, wherein formation of diester species proceeds via esterification of epoxide intermediates, and wherein the epoxide intermediates are generated via an enzymatically-driven mechanism. In some embodiments, the methods for making such diester-based lubricants utilize a biomass precursor and/or low value (e.g., Fischer-Tropsch (FT) olefins and/or alcohols) so as to produce high value diester-based lubricants. In some embodiments, such diester-based lubricants are derived from FT olefins and fatty acids. The fatty acids can be from a bio-based source (i.e., biomass, renewable source) or can be derived from FT alcohols via oxidation.

  • Patent number: 8603957
    Abstract: An automotive lubricant composition comprising a base fluid and an ashless polymeric dispersant is claimed. The ashless polymeric dispersant has a number average molecular weight of between 500 and 10,000 and comprises a polar tall group which itself comprises a polymeric backbone of 2 to 30 monomeric repeat units, each repeat unit comprising a hydrocarbon chain functionalised by the presence of at least one electronegative element or moiety, the tail group being linked to a polar head group which comprises a polar moiety selected from at least one of acid, ester, amide or alcohol moieties. The dispersant has good dispersancy properties, when used as a sole dispersant or in combination with other dispersants. It provides enhanced seal resistance and has good oxidative stability in automotive applications as compared to current commercial products.

    Abstract: A composition that includes one or more compounds represented by the formula A(B)x wherein A is the residue of an aromatic compound, B is the residue of an unsaturated hydrocarbon ester, and x is a value of 1 or greater. The composition has a viscosity (Kv100) from 2 to 40 at 100° C., and a viscosity index (VI) from 100 to 200. The disclosure also relates to a process for producing the composition, a lubricating oil base stock and lubricating oil containing the composition, and a method for improving one or more of solubility and dispersancy of polar additives in a lubricating oil by using as the lubricating oil a formulated oil containing the composition. The lubricating oils containing the composition are advantageous as engine oils that can improve engine fuel efficiency.
