Technical Abstract: Lesquerella fendleri is a member of the genus Lesquerella of the Brassicaceae (mustard) family. Lesquerella is a developing oilseed crop currently grown in the Southwestern U.S., 40 acres in 2003. The oil is very attractive due to high levels (53%) of the hydroxy fatty acid, 14-hydroxy-cis-11-eicosenoic acid (lesquerolic acid). Estolides derived from lesquerella and castor 2-ethylhexyl esters with different saturated and unsaturated fatty acids were synthesized. These new estolides produced a series of functional fluids with excellent cold temperature properties having pour points <-53 deg C. Poor cold temperature properties is one of the traditional problems with vegetable oils. However, with the addition of additives these properties can sometimes be improved. These new estolides have been designed to meet these cold weather demands without additives. Synthesis of estolides from the fatty esters will be discussed as well as their physical properties, which include pour and cloud points, viscosities, and colors. Comparisons will be made to other estolide technology and commercially available materials.
