The effect of synthetic antioxidants on the oxidative stability of biodiesel

► Studied oxidative stability of neat biodiesels using Rancimat procedure. ► Canola induction period (IP) exceeded EN 14214 requirement (>6 h). ► Adding a phosphate antioxidant destabilized canola biodiesel. ► Soybean biodiesel with 0.5% DTBHQ also passed specification.
