Abstract

A study on the production of oleic and ricinoleic acids based estolide was carried out. Polyhetero acid of 12-phosphotungsti and silicotungstic acids have been used in the reactions at 60 or 90°C, for 10 or 24 h. The mole ratio of ricinoleic to oleic acids was 2:1 and weight percentage of catalyst to the reactant used was 5%. The FTIR spectrum of the estolide product was compared to reaction product using perchloric acid as homogeneous catalyst. The estolide formation was shown by the existence of three new peaks at 1733 cm-1 for C=O ester, 967 cm-1 for-CH=CH- trans and 1177 cm-1 for C-O-C, respectively. The same FTIR spectrum pattern was observed for the reaction product using perchloric acid as homogeneous catalyst. The LC-MS analysis showed that the formation of three new monoestolide peaks at retention time (Rt) at 8.6 (m/z 577), 10.2 (m/z 559) and 12.1 min (m/z 561). The results showed that the condensation reaction between oleic-ricinoleic acids by using perchloric acid, solid acid silicotungstics and phosphotungstics acid as catalysts was successfully formed the estolides with yields percentages of 70.2, 70.0 and 60.8%, respectively.
