ABSTRACT:
Organic non-quaternary clathrate salts are useful for separating hydrocarbon feed streams into aromatics rich fraction and aromatics lean fraction. The organic non-quaternary clathrate salts are characterized by having cations containing less than 16 carbon atoms. Preferred salts are collidinium triflate and triethylammonium dihydroxybenzoate.
