Title: Optimized Antioxidants for Biodiesel
Author(s): Larson, Richard A.; Marley, Karen A.
Subject(s): Biodiesel fuels -- Research Oxidation chemistry
Abstract: Methods to improve the oxidative stability of B100 biodiesel were studied. A combination of a peroxide destroyer - triphenylphosphine - and a chain-breaking antioxidant - propyl gallate - was found to largely prevent oxidative damage in soy- and waste oil-derived biodiesels. Peroxides were shown to react rapidly with propyl gallate and render it ineffective. Triphenylphosphine alone provided some protection from oxidation, but not to the extent of the combination. Propyl gallate was found to be superior to other potential surface-active or chain-breaking antioxidants tested, such as ascorbyl palmitate, butylated hydroxytoluene (BHT), Trolox, and other gallate esters.
