Abstract

La presente divulgación se refiere a la formación de dimetil tereftalato (DMT) y monoetilen glicol (MEG). La presente también se refiere a la despolimerización del tereftalato de polietileno (PET) y la recuperación de dimetil tereftalato (DMT) y monoetilen glicol (MEG) utilizando metóxido de sodio como catalizador. Reivindicación 1: Un proceso para despolimerizar tereftalato de polietileno (PET) comprendido en un material de partida para formar dimetil tereftalato (DMT) y monoetilen glicol (MEG); siendo que dicho proceso comprende: (i) mezclar el material de partida que comprende tereftalato de polietileno (PET) con una primera porción de metanol para formar una primera mezcla; (ii) agregar metóxido de sodio a la primera mezcla; (iii) mezclar; y (iv) agregar una segunda porción de metanol para dar lugar a una segunda mezcla; como resultado de lo cual se forma tereftalato de dimetilo (DMT) y monoetilen glicol (MEG).
