FIELD: chemistry.
SUBSTANCE: invention relates to a method of dearomatising a gasoline fraction - pyrolysis material, which involves extraction of aromatic hydrocarbons from a gasoline fraction at 62-180°C, obtaining a raffinate with low content of aromatic hyrocarbons, wherein the selective solvent used is a mixture containing 50-65 wt % N-methylpyrrolidone, 30-45% triethylene glycol, 3-7 wt % water.
EFFECT: low content of aromatic hydrocarbons in the gasoline fraction.
