Abstract : Methods for inhibiting the autoxidation of organic substrates are reviewed. Antioxidants can be divided into two broad groups according to whether they reduce the rate of chain initiation (preventive antioxidants) or interfere with the normal propagation process by reacting with free radicals (chain-breaking antioxidants). Preventive antioxidants can be subdivided into peroxide decomposers, metal ion deactivators, and ultraviolet light deactivators. Chain-breaking antioxidants can be subdivided according to whether they add, donate hydrogen, or donate an electron to the chain-propagating radicals. The detailed mechanisms by which these various classes of antioxidants inhibit oxidation are discussed. (Author)
