| titleOfInvention | Improved process of removing polyethyleneterephthalate admixtures |
| abstract | The process of removing impurities from polyethylene terephthalate components by depolymerizing polyethylene terephthalate (PET), including the transesterification of a material containing PET, by reacting ethanediol with the material for a predetermined period of time at a boiling point of ethanediol or at a temperature close to it, to obtain a solution containing soluble short chains of PET polymers and / or bis (hydroxyethyl) terephthalate ester (BHT); the selection of short-chain polymers of PET and / or BHT and ethanediol; and the hydrolysis of the selected short-chain polymers of PET and / or BHT at elevated temperature and pressure for a predetermined period of time to obtain a solution of ethanediol and terephthalic acid crystals. |
