Estimation of the oxidation temperature of biodiesels from a limited number of chemical parameters

► Experimental mixture design with fatty acid methyl esters was performed to study oxidative stability. ► The oxidation temperature (OT) was obtained applying non-isothermal PDSC. ► A pseudo-molecular formula CaHbHc∗Hd∗∗He∗∗∗O2(OH)f to represent the mixtures of FAME was developed. ► A quadratic relationship for OT with H∗, H∗∗ and (OH) was found.
