  • SYNTHESIS OF DIESTER-BASED BIOLUBRICANTS FROM EPOXIDES
    Publication number: 20090198075
    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, 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.
