| titleOfInvention | Improved catalyst performance for polyester recycling |
| abstract | The present disclosure relates generally to processes for depolymerizing polyester. Accordingly, in one aspect, the present disclosure provides for a method for forming a di(C1-C6 alkyl) terephthalate from a polyethylene terephthalate-containing feedstock, the method comprising: in a reaction mixture contacting a polyethylene terephthalate- containing (PET-containing) feedstock with at least one C1-C6 alcohol in the presence of (a) a depolymerization catalyst and (b) at least one acid or acid precursor, selected from a mineral acid, an organic acid, an anhydride and an ester, said acid or acid precursor being present in a total amount of at least 0.01 wt% based on weight of the reaction mixture, to form a reaction product stream comprising ethylene glycol and di(C1-C6 alkyl) terephthalate. |
