Abstract
In this work, the aminolysis depolymerisat of poly(ethylene terephthalate) PET was carried out with ethanolamine and several acetates as catalysts. The main product, bis(2-hydroxyethyl) terephthalamide (BHETA), was identified from FTIR and 1H NMR. It was found that PET depolymerisat is favoured by increasing temperature, time and catalysts. Results shown that under present conditions of aminolysis, the conversion of PET was 100% and high yield of BHETA. Moreover, aminolysis products have the potential to undergo further reactions to yield secondary value-added product, such as unsaturated polyesters, polyurethanes, epoxy resin hardeners and non-ionic polymer surfactants. 9 Refs.
