Abstract
The present invention is generally directed to diester-based lubricant compositions comprising one or more isomeric mixtures of diester species wherein the kinematic viscosity of the composition at temperature of 100 C is at least 3 mm2/s The present invention is also directed to methods of making these and other similar lubricant compositions. In some embodiments, the methods for making such diester-based lubricants utilize a biomass precursor material from which mono-unsaturated free lipid species can be provided or otherwise generated, wherein such mono-unsaturated free lipid species are converted to isomeric diol species en route to the synthesis of diester species for use as/in the diester-based lubricant compositions.
