Abstract: Provided is a PET chemical recycling method. The PET chemical recycling method includes the following: adding a PET chemical recycling ion catalyst material for PET chemical recycling to PET waste and ethylene glycol; heating and stirring to obtain depolymerized and decolorized bis(2-hydroxyethyl)terephthalate (BHET); and filtering and recycling the ion catalyst material for PET chemical recycling. The PET chemical recycling ion catalyst material is a bisalkylimidazole-metal tetrachloride ionic liquid grafted on a porous carrier.

Abstract: A method of chlorinating a antimony fluorohalide catalyst is disclosed. In one embodiment the method comprises contacting an antimony fluorohalide catalyst that contains one or more fluorines with a regenerating agent chosen from 2-chloro-3,3,3-trifluoropropene (1233xf), 1,1,1,3-tetrachloropropane (250fb), 2-chloro-1,1,1,2-tetrafluoropropane (HCFC-244bb) and combinations of 1233xf, 250fb, and 244bb, under conditions effective to exchange at least one fluorine in the antimony fluorohalide catalyst with chlorine. The method can be used to regenerate spent antimony fluorohalide catalyst, for example regenerating SbCl5 from SbF5.
