Alkyl diphenylamine is a class of high-performance amine-type antioxidants, which is prepared by the alkylation reaction of diphenylamine with different olefins. The alkyl groups introduced into the molecular structure can significantly improve its oil solubility and compatibility with various lubricating oil base stocks, making it suitable for use in a wide range of lubricant formulations.
In terms of core functions, alkyl diphenylamine has two key application values in the lubricant industry. First, it acts as an excellent antioxidant and anti-aging agent. It can effectively capture free radicals generated during the high-temperature oxidation process of lubricating oils, terminate the chain reaction of oil oxidation, and inhibit the formation of harmful substances such as sludge, colloid and acidic components. This function helps to extend the service life of lubricants and maintain the cleanliness of mechanical equipment, especially for equipment operating under high-temperature and long-term working conditions. Second, it has a good anti-corrosion effect. It can form a protective adsorption layer on the metal surface, isolating the metal from corrosive media such as acids and moisture generated during equipment operation, thus preventing metal parts from being corroded.
In addition, alkyl diphenylamine shows good synergistic effects when used together with other types of antioxidants, such as phenolic antioxidants and zinc dialkyldithiophosphate. This synergism can further enhance the overall oxidation resistance of lubricants. It is widely used in engine oils, gear oils, hydraulic oils and industrial lubricants, and is particularly suitable for high-performance lubricant formulations with strict requirements on high-temperature stability.
