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 and/or low value Fischer-Tropsch (FT) products (e.g., alcohols) so as to produce high value triester-based lubricants. In some embodiments, such triester-based lubricants are derived, at least in part, from FT alcohols 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.
An industrial oil composition comprises a major amount of an ester base oil comprised of at least one diester or triester species having a vicinal diester substituent and at least one additive. The use of such esters can provide biodegradable industrial oils having improved viscosity index, additive solvency, or both.
