| Popis: | Comparative experimental data on the four-step countercurrent extraction treatment of a mixture of naphthene vacuum gas oil and residual extract with dimethyl sulfoxide and with a 90 : 10 (wt %) mixture of N-methylpyrrolidone with ethylene glycol are presented. The mixed extractant based on N-methylpyrrolidone, compared to dimethyl sulfoxide, ensures more exhaustive removal of eight carcinogenic polycyclic arenes, including benzo[a]pyrene, from aromatic softener oil at a lower extractant to feed ratio. |
