Mixture a1 is extractively distilled with extractive solvent a2 producing mixture bl comprising solvent a2, aromatic hydrocarbons and high boilers, and nonaromatic hydrocarbon mixture b2. Mixture b1 is distilled to aromatic hydrocarbon c1 and solvent comprising high boilers c2. Substream dl is removed from c2 and c2 is recycled to extractive distillation.
