Title:
METHOD FOR PRODUCING HIGH VALUE-ADDED COMPOUNDS FROM POLYETHYLENE TEREPHTHALATE
Document Type and Number:
WIPO Patent Application WO/2020/209607
Kind Code:
A1
Abstract:
The present invention pertains to a method for producing high value-added compounds from polyethylene terephthalate. More specifically, the present invention demonstrates that a monomeric terephthalic acid obtained from the chemical hydrolysis of polyethylene terephthalate can be converted to high value-added aromatic compounds and aromatic-derived compounds, and ethylene glycol, which is another monomer of polyethylene terephthalate, can be converted to glycolic acid, which is a cosmetic material. The present invention is characterized by recycling polyethylene terephthalate waste into high value-added compounds.
