The interaction of zinc dithiophosphate and phenolic antioxidants with metal naphthenates, mainly with copper naphthenate, has been investigated. A complex compound is formed on the interaction of zinc dithiophosphate with copper naphthenate; this has a noticeable influence on the antioxidation effectiveness of zinc dithiophosphate. The possibility of increasing the antioxidising action of zinc dithiophosphate through its combination with a copper passivator is shown. The formation of complex compounds on the interaction of phenolic antioxidants with copper naphthenates depends on the structure of these additives.
