Method for recovering high-purity monomer from polyester, high-purity monomer, polyester |
| abstract |
An object of the present invention includes a metal derived from an esterification and / or polymerization catalyst in the production of polyethylene terephthalate, and from a polyethylene terephthalate product and / or waste to which a solvent or a chemical substance is attached. It is the point which removes a foreign material efficiently and obtains the decomposition products terephthalic acid and ethylene glycol with high purity. A method of recovering a product comprising polyethylene terephthalate as a main component and / or waste thereof and recovering an active ingredient, in recovering a raw material monomer, pressure: 10 to 30 MPa, temperature: 200 to 400 A method for recovering a high-purity monomer from polyethylene terephthalate, wherein the hydrolysis reaction is carried out in the presence of water having a relative dielectric constant of 40 or less at ° C. |
