Investigation of Antioxidative Properties of Multifunctional Additives of Alkyl Phenolate Type and Development of New Lubricant Compositions

作者：Yulduz Beyuk Aga Ramazanova

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.
