Investigation on glycolysis of PET catalyzed by dual task special ionic liquids
Abstract: Under the condition of 180℃ or 190℃ respectively, waste polyethylene terephthalate(PET) was glycolyzed using ethylene glycol as solvent and ionic liquids as catalyst such as [NH2Mim]IM, [NH2Mim]Br and [NH2Mim]OH. The results showed that the effect of glycolysis of PET catalyzed by [NH2Mim]IM at 190℃ is best, the product was separating easily, conversion and yield are high; Followed by [NH2Mim]IM; The effect of glycolysis of PET catalyzed by [NH2Mim]Br ionic liquid is bad, the catalyst with high viscosity was difficulty to access. Under the ideal conditions, three samples was glycolyzed changing the kinds of PET. The results showed that the effect of glycolysis of sample three is best.
Key words: Ionic liquids; PET; Glycolysis
