| 摘要 |
The present invention relates to a method of recovering a solution comprising the chemical species obtained by depolymerization of PET from a material containing poly(ethylene terephthalate) in the form of bottles, by making said material react, in the absence of water, with a reagent consisting of one or more metal salts of a weaker acid than the terephthalic acid and of ethylene glycol, until a water-soluble intermediate product is obtained, and subsequently carrying out dissolution in water, stirring and filtering.
