Interpretive Summary:

Technical Abstract: The development of a new crop often depends on the synthesis of novel compounds. Estolides are one such derivative of new crop oils which show promise in industrial applications. Estolides are formed when the carboxylic acid functionality of one fatty acid links to the site of unsaturation of another fatty acid to form esters. Estolides were derived from a number of unsaturated fatty acids in the presence of varying equivalents of acid with little or no solvent at various temperatures. Estolides were also linked to different acids. The estolides were converted to their corresponding hydroxy fatty acid and the degree of polymerization was determined by GC analysis. The free acid estolides were then converted to the esters under standard conditions. Physical properties (pour points, cloud points and viscosities) of the complex estolide acids and esters were compared to the homo-estolides, which have current industrial applications.
