Короткий опис (реферат):
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.
