摘　　要：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 theАПСМ-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.
