Such substances thus act as inhibitors by keeping the concentration of potential initiator low. Aromatic amines and phenols are also widely used as antioxidants. Generally, these types of substances are believed to function by undergoing hydrogen atom transfer with alkylperoxy radicals in preference to hydrocarbons. The resulting radicals are relatively stable and do not propagate a chain process, but instead dimerize or react in other ways to effect chain termination. [Pg.522]

Speaking of an antioxidant generally, its activity is required to act as a hydrogen donor and neutralize free radicals. On the other hand, aromatic rings play a signi cant role and phenolic hydroxyl groups enhance the inhibition of oxidation (Giilcin, 2011). [Pg.339]

Tobias Acid to- bl-os a-sod n Intermediate used in the manufacture of dyestuffs. 2-naphthylamine-l-sulfonic antioxidant, generally regarded as safe by the Food and Drug Administration. It has been shown to be a good heat stabilizer in polyolefins, providing protection at levels around 250 ppm. Both ATP and its breakdown products are environmentally safe. [Pg.753]
