Development of new C, S, N-containing plastic lubricants based on products from industrial waste integrated processing

Abstract

The object of this research is the integrated processing of industrial waste from various indus tries, which makes it possible to reduce the use of material and energy resources and improve the ecological state of the environment. Waste from the chemical, petrochemical, and machine-build ing industries was subject to integrated technolog ical processing. The common link that united the investigated complex technological cycles was the use of a regen erated mixed sorbent (activated carbon+kiesel guhr), on the surface of which topochemical trans formations of chemicals that were part of industrial waste took place. Using a regenerated mixed sor bent, exhausted industrial oil which was the min eral basis of the developed new C, S, N-containing plastic lubricants was purified. In particular, we have established the conditions for obtaining dieth yl ammonium chloride from unusable pesticides of the formula R1R2R3R4C6HCOOH∙HN(C2H5)2, whose topochemical interaction on the surface of the mixed sorbent leads to the formation of a sorbed fragment [sorbent (activated carbon+kie selguhr)]∙[(C2H5)2NC(=S)SK]. Subsequent inter action of aqueous solutions containing copper(II) ions with such a fragment leads to the formation of bis–(diethyldithiocarbamate)copper(II) on the surface of mixed sorbent. The resulting substanc es of the general composition [sorbent (activat ed carbon + kieselguhr)]∙{[(С2H5)2NC(=S)S]2Cu} were studied as thickeners and active polyfunc tional components of the obtained plastic lubri cants. Research into the tribological properties of new C, S, N-containing plastic lubricants showed their high anti-wear and heat-resistant properties and the possibility of effective use in highly loaded friction nodes.
