Epoxidation kinetics and thermodynamics of Jatropha curcas L. oils

Epoxidation of methyl ester of Jatropha curcas seed oil (JCO) was carried out at different temperature using peroxformic acid prepared in situ by reacting hydrogen peroxide with formic acid in the presence of toluene. The chemical properties of methyl ester JCO was investigated. The rate constant an...
