Abstract—The results of the chromatographic analysis of coal tar for the concentrations of phenols and their
derivatives are given. It was shown that coal tar from AO Sary-Arka Spetskoks is characterized by a high con-
centration of phenols, which serve as a source material for organic synthesis. The possibility of applying ethanol
and cavitation treatment to the extraction of phenols from the coal tar was established. The following optimum
process conditions were found: ethanol concentration, 55–70%; duration, 5–7 min; the ratio ethanol : tar = 2 :
1; and the temperature of the cavitation treatment of primary coal tar, 333 K. A diagram for the extraction-cav-
itation treatment of primary coal tar was proposed.
