Investigation on thermal degradation properties of oleic acid and its methyl and ethyl esters through TG-FTIR

•Reactivity of the esterification derivants is heightened in comparison with the feedstock.•Iso-conversional approaches are used to calculate the apparent kinetic parameter.•Apparent reaction order of the thermal degradation is estimated by Avrami theory.•The apparent enthalpy change, Gibbs free ene...
