| titleOfInvention | Method for recovering ethylene glycol and method for producing polyester using the same |
| abstract | The present invention provides a method for recovering ethylene glycol with high purity from a washing liquid after washing a polybutylene terephthalate production apparatus with ethylene glycol, and a method for producing a polyester excellent in heat resistance. When washing an apparatus for producing polybutylene terephthalates, after washing with ethylene glycol, an acid component is added to the ethylene glycol used for the washing, followed by heat treatment, and ethylene glycol is recovered by distillation. And a method for recovering ethylene glycol. [Selection figure] None |
