Abstract:
A process for chemically recycling polyethylene terephthalate (PET) which utilizes a microwave absorber to optimize glycolytic depolymerization of PET via microwave irradiation. The method of chemically degrading PET to its reactive intermediate, bis(2-hydroxyethyl) terephthalate (BHET), is carried out by: (a) combining PET with ethylene glycol and a catalytic system comprising a catalyst and a microwave absorber to produce a heterogeneous reaction mixture; and then (b) heating by microwave irradiating the reaction mixture to a temperature sufficient to produce a reaction product comprising BHET. The BHET monomer then can be purified and re-polymerized to form new, virgin PET.

Claim (Index 4):
The method of  claim 3 , wherein the catalyst is selected from the group consisting of: zinc acetate, zinc chloride, manganese acetate, 1, 5, 7-triazabicyclo[4.4.0]dec-5-ene (TBD), 1, 8-diazabicyclo[5.4.O]undec-7-ene (DBU), magnesium acetate, 4-dimethylaminopyridine (DMAP), and combinations thereof.
