Kinetic study of catalytic glycolysis of PET wastes with zinc acetate

Poly(ethylene terephthalate) (PET) was depolymerized by di-ethylene glycol (DEG) in the presence of zinc acetate. Qualitative analysis showed that the main product from glycolysis was bis(hydroxylethyl) terephthalate. Fourier Transform infra-red (FTIR) was used for characterization of product while...
