The results of studies of the antioxidant properties of multifunctional alkylphenolate type additives indicate the calcium salts of condensation products of alkylphenols (C₈ - C₁₂) with formaldehyde and the following amines: aminoacetic acid, benzotriazole, diethanolamine and boric acid, as well as their carbonated compounds. The determination of the antioxidant properties of the additives is tested on the АПСМ-1M apparatus. New lubricant compositions for diesel internal combustion engines oil meeting the required standards for these oils have been developed. The study of additives, which possess simultaneously detergent-dispersing, neutralizing, antioxidant anti-wear properties, revealed the dependence of antioxidant properties on their alkalinity.
