The results of the extraction of thiophene, dibenzothiophene, diphenylamine, indole, carbazole, fluoranthene and pyrene from model mixtures with n-undecane, as well as thiophene from a mixture with n-heptane at a content of the extractable component in the binary system of 10% wt. are presented. A mixed solvent N-methylpyrrolidone - ethylene glycol with the composition of 90/10% wt. at 25 °C was used for the extraction. The experimental data obtained were compared with the results of the extraction of the same components from model mixtures with n-undecane by pure N-methylpyrrolidone
