Method for producing terephthalic acid and method for producing recycled polyethylene terephthalate |
| abstract |
This method for producing terephthalic acid has: a first hydrolysis step for hydrolyzing polyethylene terephthalate by exposing a material to be treated that contains polyethylene terephthalate, which has been stored in a sealed container, to an atmosphere of from normal pressure to saturated water vapor pressure, and obtaining a hydrolysate containing terephthalic acid and/or an ethylene terephthalate oligomer; and a second hydrolysis step for obtaining terephthalic acid by hydrolyzing, in hot water, the ethylene terephthalate oligomer obtained in the first hydrolysis step, the weight of hot water in the second hydrolysis step being twice or more the weight of the material to be treated used in the first hydrolysis step. |
