ABSTRACT
Oxidation of organic compounds is one of the efficient methods of organic synthesis in
modern petrochemical industry. On the other side, the autoxidation of organic compounds,
their mixtures, and products promotes their rapid deterioration due to the action of atmos-
pheric oxygen. Products such as rubber, polymers, hydrocarbon fuels, lubricants, organic
solvents, semiproducts, food, drags, etc. are spoiled due to oxidation by oxygen. Antioxidants
prevent the rapid development of these undesirable processes. They were the object of
intensive study during the last 40 years. The practical use of antioxidants began in the end
of the 19th century.
