    摘要: Disclosed are extraction solvents used in compositions and methods to refine synthetic feedstocks derived from plastic. Methods of refining plastic-derived synthetic feedstocks are also provided. For example, a method of refining a plastic-derived synthetic feedstock composition may include adding an extraction solvent to a synthetic feedstock composition derived from plastic pyrolyis to provide an extract phase and a raffinate phase, wherein the extraction solvent includes a polar organic extraction solvent immiscible in the synthetic feedstock. The methods may also include separating the raffinate phase from the extract phase to obtain a refined synthetic feedstock.
