Selective Solubilization of Hydrocarbons From Mixtures

Amounts of benzene and hexane solubilized from a binary hydrocarbon mixture into a micelle made up of Polyvinyl pyrrolidone – Polystyrene (PVP-PS) diblock copolymer, with a PS core. Over the entire composition range of the hydrocarbon mixture, benzene is preferentially taken up by the micelle allowing the design of micellar systems for selective chemical extractions.
