  • Patent number: 7867959
    Abstract: The present invention is generally directed to methods of making diester-based lubricant compositions, wherein formation of diester species proceeds via direct esterification of epoxide intermediates. 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 tatty 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.

    Abstract: The present invention is generally directed to triester-based lubricant compositions. The present invention is also directed to methods of making these and other similar lubricant compositions. In some embodiments, the methods for making such triester-based lubricants utilize a biomass precursor comprising mono-unsaturated fatty acids, wherein such mono-unsaturated fatty acids are reduced to mono-unsaturated fatty alcohols en route to the synthesis of triester species for use as/in the triester-based lubricant compositions. Subsequent steps in such synthesis may employ carboxylic acids and/or acyl halides/anhydrides derived from biomass and/or Fischer-Tropsch synthesis.

  • Publication number: 20100035779
    Abstract: A grease which comprises a base oil containing at least 50% by mass of a diester compound having a total carbon number of 28 to 40 and represented by the general formula (I): R1OOC—(R2)n—COOR3 ??(I) wherein R1 and R3 each independently represent a C4 to C20 monovalent aliphatic hydrocarbon group, R2 represents a C1 to C20 divalent hydrocarbon group and n is 0 or 1. The grease is excellent in both low-temperature performance and high-temperature performance and has low oil separation tendency even under high centrifugal force (acceleration). In particular, when the grease is used in a rotational transmission device having a built-in one-way clutch, the grease can provide satisfactory clutch engagement property (intermeshing ability) at low temperatures and a prolonged bearing life at high temperatures and is less apt to cause oil separation under high centrifugal force.
