Autoxidative processes of mono- and trilinolein and mono- and trilinolenin were observed at different temperatures. Rate expression of the autocatalytic type was applicable to the entire autoxidative process of mono- and trilinolein at any temperature. The rate expression could also be applied to the first-halves of autoxidation of mono- and trilinolenin, although the latter halves did not obey the expression but first-order kinetics. The rate constants for each substrate were evaluated at different temperatures, and the apparent activation energy and the frequency factor were estimated. From these two parameters obtained here and reported previously, it was demonstrated that the enthalpy-entropy compensation held in autoxidation of fatty acids, their ethyl esters and acylglycerols.
