摘要

A comprehensive analytical method atomic pressure chemical ionization tandem mass spectrometry (APCI-MS/MS) with positive ionization mode to identify the oxidation products of biodiesel has been developed. Structural elucidation of various oxidation products by accelerated oxidation was carried by HCD and exact mass analysis using FT-Orbitrap Mass Spectrometer. The composition of oxidized biodiesel was changed to decrease unsaturated bond. Oxidation compounds were increased. The proposed dimer of oxidation products under accelerated oxidation was produced thermal polymerization by Diels-Alder reaction.
