Abstract

Un proceso para reciclar químicamente tereftalato de polietileno (PET) que utiliza un absorbedor de microondas para optimizar despolimerización glucolítica de PET vía irradiación de microondas. El método de degradar químicamente PET a su intermedio reactivo, bis (2-hidroxietil) tereftalato (BHET), se lleva a cabo mediante: (a) combinar PET con etilenglicol y un sistema catalítico que comprende un catalizador y un absorbedor de microondas para producir una mezcla de reacción heterogénea; y después (b) calentar por irradiación de microondas la mezcla de reacción a una temperatura suficiente para producir un producto de reacción que comprende el BHET. El monómero BHET se puede purificar y re-polimerizar para formar un nuevo PET virgen.
