Abstract
The article is devoted to the study of the anticorrosive properties of sulfonate additives mixed with HC4 hydrocracking base oil. The results of a study of the anticorrosive effectiveness of sulfonate additives NSSK-30, S-150, SSK-400 are presented. The patterns of changes in the protective properties of synthetic sulfonate additives depending on the value of their alkaline number have been revealed. A qualitative and quantitative assessment of the effectiveness of using sulfonate additives in a mixture with HC4 base oil as inhibitory compounds to protect steel from corrosion under the action of an electrolyte, in a climatic chamber and a salt mist chamber was carried out. It has been shown that the effectiveness of the protective action of inhibitory compounds increases with a decrease in the alkaline number of the sulfonate additive. The nature of the change in the surface of steel plates in the process of their corrosion destruction, accompanied by the formation of pitting, is revealed.
