Abstract
Abstract Vegetable oil-based oils usually fail to meet the rigorous demands of industrial lubricants by not having acceptable low temperature properties, pour point (PP) and/or cloud point (CP). Oleic estolide was produced from oleic fatty acid and a catalytic amount of perchloric acid. The oleic estolide was then esterified with a series of 16 different alcohols that were either branched or linear-chained. The new estolide esters physical properties were recorded and evaluated as a potential industrial lubricant. The linear-chain esters had higher low temperature properties (PP = −9 to −33 °C) but still compete well with other commercial bio-based materials. The oleic estolide ethyl ester yielded the best PP at −33 °C for the linear-chain series. The branched alcohol produced the best PP (−24 to −39 °C) and CP (−30 to
