Abstract: Methods for making diverse high-quality biolubricants using carboxylic acid and dicarboxylic acids produced from ozone cracking of lipids. The method can include reacting a fatty acid with one or more alcohols, diols, and/or triols to esterify the fatty acid to form esters having a viscosity index of from 100 to 185, according to ASTM-D2270. The methods can also include reacting a carboxylic acid and/or dicarboxylic acid with one or more alcohols, diols, and/or triols to esterify the acid to form one or more diesters and/or oligoesters having a viscosity index of from 100 to 185, according to ASTM D 2270. The carboxylic acids and dicarboxylic acids can be nonanoic acid, malonic acid, propanoic acid, hexanoic acid, and azelaic acid, and can be derived from oxidation of one or more lipids by ozone cracking.

Abstract: A method for predicting yield and composition changes during urea inclusion fractionation to select a fatty acid methyl ester source for biofuel. The method can include heating a solid urea inclusion compound to a decomposition temperature, allowing the solid urea inclusion compound to decompose, heating again to a melting temperature, allowing the solid urea to melt, cooling to the decomposition temperature, and cooling again to a temperature below the decomposition temperature. Each heating, cooling, decomposing, and melting step can have its change in enthalpy and entropy recorded. A thermodynamic model can be calculated using the recorded changes in enthalpy and entropy. The thermodynamic model can predict a yield and composition of the solid urea inclusion compound and can be used to select a fatty acid methyl ester source using the predicted yield and composition.

Abstract: Methods for making biofuels, such as biokerosene, from various alcohols and nonanoic acid, a primary product of the ozonolysis of oleic acid. The products exhibit excellent low-temperature performance. Cloud points of the nonanoic esters range from −35 to −70° C. This super low-temperature performance shows the potential for replacing winter-season diesel, kerosene, and jet fuels. The products also show excellent oxidation stability and low greenhouse gas emissions. The energy densities of the products increase with the carbon atoms in the alcohols and are less than current biodiesel. The products generally have flash points higher than 90° C., indicating safer handling and storage. Compared to current biodiesel, the products have no issues with the cold soak filtration test.
