Process for the recycling of polyethylene terephthalate by glycolysis comprising a stage of separation of other polymers

Abstract

and being carried out in a liquid reaction medium, b) a dissolution of the polymer other than PET comprising a mixing with a solvent immiscible with the liquid reaction medium of stage a) making it possible to dissolve the polymer other than PET, b’) a separation, from the liquid reaction medium, of the immiscible solvent resulting from stage b), said stages b) and b’) being carried out independently during or after the depolymerization stage a), said process producing a purified BHET-comprising effluent.
