Abstract
Disclosed is a method of producing an estolide, including a) converting biomass-derived oil into a fatty acid mixture, b) separating the fatty acid mixture into a C16 saturated fatty acid and a C18 unsaturated fatty acid, c) converting the C16 saturated fatty acid into a C15 or C16 linear internal olefin, d) subjecting the C15 or C16 linear internal olefin to an estolide reaction using a linking agent, thus obtaining an estolide A, e) subjecting the C18 unsaturated fatty acid to partial hydrogenating to increase the amount of oleic acid, and f) subjecting the oleic acid to an estolide reaction using a linking agent and then esterification, thus obtaining an estolide B.

A method of producing an estolide, comprising:
- a) converting biomass-derived oil into a fatty acid mixture;
- b) separating the fatty acid mixture into a C16 saturated fatty acid and a C18 unsaturated fatty acid;
- c) converting the C16 saturated fatty acid into a C15 or C16 linear internal olefin;
- d) subjecting the C15 or C16 linear internal olefin to an estolide reaction using a linking agent thus obtaining an estolide A;
- e) subjecting the C18 unsaturated fatty acid to partial hydrogenating to increase an amount of oleic acid;
- and
- f) subjecting the oleic acid to an estolide reaction using a linking agent and then esterification, thus obtaining an estolide B.
An estolide, comprising at least one selected from the group consisting of:
- an estolide A, configured such that a carboxylic acid functional group of a linking agent is linked to a position of a double bond in a C5 or C16 linear internal olefin;
- an estolide B in ester form, configured such that a carboxylic acid functional group of a linking agent is linked to a position of a double bond in oleic acid;
- and
- an estolide C, configured such that a carboxylic acid functional group of a linking agent is linked to a position of a double bond in a C17 or C18 linear internal olefin.
