Separation of components from aromatic hydrocarbon mixtures thereof by extractive distillation

Image Number 2 for United States Patent #6395141.

A method of separating aromatic hydrocarbons and non-aromatic hydrocarbons, and aromatic hydrocarbons and naphtenes involves distilling a mixture of the components by an extractive distillation process in the presence of an extractive distillation solvent. The extractive distillation solvent may be an ester of a dibasic acid, an acetonyl acetone or morpholine.
