| titleOfInvention | Process for producing bis-β-hydroxyethyl terephthalate and / or its low condensate |
| abstract | PROBLEM TO BE SOLVED: To efficiently decompose an aromatic polyester in a highly crystallized state, for example, a recovered fiber comprising an aromatic polyester, a fiber layer, or even a recovered bottle having a neck portion with a high degree of crystallinity. Provided is a method for producing bis-β-hydroxyethyl terephthalate and / or a low condensate thereof. SOLUTION: An aromatic polyester having terephthalic acid as a main dicarboxylic acid component and ethylene glycol as a main glycol component is heated with bis-β-hydroxyethyl terephthalate and / or a low condensate thereof to predecompose the aromatic polyester. And then reacting the obtained pre-decomposed product with ethylene glycol to convert the terephthalic acid component of the pre-decomposed product into bis-β-hydroxyethyl terephthalate and / or a low-condensate thereof. A method for producing β-hydroxyethyl terephthalate and / or a low condensate thereof. |
