Abstract

Aromatic hydrocarbons of increased purity are obtained in a selective solvent extraction process comprising an extraction step followed by one or more distillation steps by introducing a low boiling hydrocarbon fraction into at least one of the distillation steps. Optionally, the low boiling hydrocarbon fraction may be obtained from the feed mixture to the process.
