Abstract

Non-aromatic 6-9C aromatic hydrocarbon mixture (hexane/benzene) is extracted with a primary solvent selective for aromatics (sulpholane) and pure aromatics are separated from the extract. The raffinate, non-aromatics + primary solvent + more than 1% vol. aromatics, is extracted with an aqueous solvent which removes primary solvent. The second raffinate which has a reduced aromatic content, is hydrogenated to convert aromatics to naphthenes. The product contains less than 1 vol. % aromatics and less than 10 p.p.m. primary solvent, and is esp. used as a solvent for edible oils.
