New recycled polyethylene terephthalate imidazolium ionic liquids and their applications for co₂ exhaust capture.

ABSTRACT: The recycling of polyethylene terephthalate (PET) waste using imidazolium ionic liquids IILs to capture CO₂ exhaust offers a sustainable and environmentally friendly approach to addressing the challenges of plastic waste pollution. The functionalized imidazolium acetate with two hydroxyl and amine end groups were prepared by simple method for glycolysis and amidolysis PET to produce water soluble oligomers during short reaction time at 180 °C. ¹HNMR analysis was used to determine the functionality and molecular weight of recycled PET oligomers with 1,3-bis(2-hydroxyethyl)-1H-imidazol-3-ium acetate ionic liquid (HIIL) and 1,3-bis(3-aminopropyl)-1H-imidazol-3-ium acetate ionic liquid (HIIL) AIIL that were 3565.7 and 1316.23 g.mol^-1, respectively.
