Monoester-based lubricants and methods of making same

摘要

The present invention is generally directed to monoester-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 monoester-based lubricants utilize a biomass precursor and/or low value Fischer-Tropsch (FT) olefins and/or alcohols so as to produce high value monoester-based lubricants. In some embodiments, such monoester-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.

1. A lubricant composition comprising:
an isomeric mixture of at least one monoester species, the monoester species being a secondary monoester and having the following structure: having a total carbon number ranging from C8 to C40, wherein R1, R2, and R3 are independently selected from alkyl groups; and a base oil selected from the group consisting of Group I oils, Group II oils, Group III oils, and mixtures thereof.
