| 논문초록 | Glycolysis has been considered one of the most promising pathways for converting poly(ethylene terephthalate)(PET) into monomeric feedstock—bis(2-hydroxyethyl) terephthalate (BHET)—which can be used as a starting material to produce virgin PET. In this process, metal-salts, such as zinc acetate, are generally used as a catalyst for glycolysis of PET. However, metal-based salt catalysts can be included in the final products, critically reducing the quality of the chemically recycled PET. Here, we present a new organic catalyst based on polyelectrolytes which offer excellent thermal stability, ease of separation and reusability. Among various types of polyelectrolytes, polyanion which synthesized based on imidazolium-acetate shows high depolymerization yields(>94%), while polycations show significantly lower efficiency. |
