Abstract
Antioxidants play a very important p rt in many chemical industries in protecting petroleum products, rubber, foodstuffs, resins, fats, oils, soaps, and a variety of chemicals from atmospheric oxidation during their manufacture, storage, and use. Phenolic compounds comprise one of the important groups of antioxidants and within this group are the hindered phenols, many of which are very efficient oxidation inhibitors. Hindered phenols are monohydric phenols whose two ortho-positions are occupied by tertiary butyl or larger groups thus hindering the phenolic properties of the compound. They are insoluble (132) in aqueous or alcoholic alkali solutions and will not respond to most of the conventional tests and reactions of phenols. This study was concerned with this class of compounds and especially with 2,6-di-tert-butyl-L-methylphenol or 2,6-di-tertbutyl- p-cresol (hereafter designated DBPC) and its use as an antioxidant in petroleum oils. It was hoped that by inv stigating the mechanism of the oxidation, a further insight into the effect of the substi tuent groups ould be attained with the aim that such information might lead to the synthesis of still more effective antioxidants.
