Interpretive Summary:

Technical Abstract: Oleic acid and linoleic acid are the most abundant fatty acids of cottonseed oil. As part of a project to develop new value-added industrial applications for cottonseed oil (such as biodiesel, fuel additives, and lubricants), studies were conducted in the synthetic conversion of oleic acid to branched-chain fatty acids. The conversion of vegetable oils to esters of branched-chain alcohols has been reported to improve low-temperature properties, demonstrated by reduced crystallization onset temperatures. Simple monoalkyl esters containing branched-chain fatty acids could have improved or superior low-temperature properties. In these studies, methyl oleate was brominated in the allylic position and subsequently treated with organocuprate reagents to produce novel branched-chain derivatives (methyl, n-butyl, phenyl). Details of the syntheses, characterization, and properties of the products (with emphasis on low-temperature properties) will be discussed.
