Abstract
In this work, glycolysis of post-consumer polyethylene terephthalate with simultaneous dissolution and decomposition with a mixture of bis(2-hydroxyethyl) terephthalate and its oligomers is studied. High efficiency of this process was shown. For the glycolysis agent containing 75 wt% bis(2-hydroxyethyl) terephthalate and 25 wt% dimer and oligomers, the optimal molar ratio of the glycolysis agent units to the polyethylene terephthalate units is 5:1. On the basis of the process, a productive and cost-effective technology can be developed for the chemical destruction of post-consumer polyethylene terephthalate. A formula for calculating the bis(2-hydroxyethyl) terephthalate conversion taking into account the presence of oligomers in it is proposed.
