Annotatsiya

In this study, secondary polyethylene terephthalate (PET), an industrial waste, and monoethanolamine were treated in a ratio of 1:2.5 without the presence of a catalyst. The aminolysis process was carried out stepwise at 100-190 0 C for 5 hours. The resulting product fractions were separated and crystallized with twice their mass of water. The resulting product was separated into fractions using a vacuum filter. The filtrate was found to have a high yield of bis(2-hydroxyethyl)terephthalamide (BHETA) of 80%. The product was analyzed using IR spectroscopy. This article proposes an energy-efficient, environmentally friendly and catalyst-free method for obtaining value-added products from PET waste by recycling.
