ABSTRACT
The research on the reagent extraction of sulfides from water-alkaline solutions was presented in the article with the purpose of their possible practical use as a component of special high-temperature grease in high-friction steam. The conditions for obtaining pentasulfide sodium and its adsorption on mixed sorbents (AC + K) were established. The complex-coordination mechanism of copper (II) sulfide formation and the method of obtaining new carbon-sulfur-containing plastic oils were offered, as well as their tribological properties in the friction pairs of roller four-row bearings were investigated.
