Process of regeneration of terephthalic acid (tpa) from the depolymerization reaction of poly (ethylene terephthalate) (pet) recycled via alkaline hydrolysis in pure ethylene glycol (eg)

摘要

"TREATENIC ACID (TPA) REGENERATION PROCESS FROM THE RECYCLED POLY (ETHYLENE TEREPHALATE) REACTION ACTION BY ALKALINE HYDROLYSIS IN THE MEDIA A PURE CHEMICAL PROCESS" regeneration of terephthalic acid (TPA) from the depolymerization reaction of recycled poly (ethylene terephthalate) (PET) via alkaline hydrolysis in pure ethylene glycol (EG) medium which, according to its general characteristics, has as its basic principle the formation of its own specific process for obtaining terephthalic acid (TPA) directly from the alkaline hydrolysis reaction of PET (polyethylene terephthalate) in pure ethylene glycol (EG) medium at atmospheric pressure at the maximum temperatures reached by each mixture , with a view to obtaining this high purity input in order to add high quality, economy and commercial value to the recycled material.
