Abstract : In 1945 the Laboratory for the Synthesis of Oil Additives AzNII was formed, and in 1965, the Institute of Additive Chemistry was organized in Baku to serve as a center for experimental and theoretical studies for heavy industry. Their work on antioxidant, anticorrosion, antiwear and multifunctional oil additives is reviewed. Antioxidants based on nitrogen-containing compounds were prepared by condensation of alkylphenols with formaldehyde and carbamide, thiocarbamide, aliphatic and aromatic amines, or urethanes. Phosphorus- and sulfur-containing compounds prepared by condensation of alkylphenols or their sulfides with formaldehyde and amines or aniline and reaction with phosphorus trichloride are effective additives. AzNII-10 is based on p-tert. amylphenol. INKhP-21 and INKhP-25, condensation products of alkylphenols, formaldehyde, and an amine treated with phosphorus pentachloride and barium oxide hydrate, have antioxidant and anticorrosive properties. BFK is the reaction product of alkylphenol, formaldehyde and hydrated barium oxide. Sulfur-, chlorine-, and phosphorus-containing compounds impart antiwear properties. (Author)
