Metal-catalysed Poly(Ethylene) terephthalate and polyurethane degradations by glycolysis

The recovery of Polyol from PolyUretane (PU) and Bis(2-HydroxyEthyl) Terephthalate (BHET) from Poly(Ethylene) Terephthalate (PET) from plastic waste by transesterification reactions was achieved, by using a wide scope of simple air-stable metal salts, Lewis acids, mixtures of commercially available phosphine/phosphite ligands with metal salts and low-valent [Ni(COD)2] as catalytic precursors, in the presence of ethyleneglycol as a...
