Diels–Alder cycloaddition of biomass-derived 2-pyrone coumalic acid (CMA) with propylene provides an alternative pathway to produce toluic acid (TA), a precursor to terephthalic acid (TPA) which is a key component in the manufacture of polyethylene terephthalate (PET).

The effects of different temperatures on catalytic hydrolysis of polyethylene terephthalate(PET) by zinc sulfate as a catalyst under microwave irradiation were studied, and in the meantime, the relation between the depolymerization rate of PET and the yield of terephthalic acid(TPA) under the same temperature was investigated. The results suggested that the reaction temperature was an important influencing factor for the depolymerization reaction of PET, and the concentration of depolymerization product TPA and the depolymerization rate of PET became coherence under the same temperature.

In this study, a novel idea was proposed to convert the polyethylene terephthalate (PET) waste drinking-water bottles into activated carbon (AC) to use for waste cooking oil (WCO) and palm fatty acid distillate (PFAD) feasibility to convert into esters. The acidic and basic char were prepared by using the waste PET bottles. The physiochemical properties were determined by employing various analytical techniques, such as field emission scanning electron microscopy (FESEM), thermogravimetric analysis (TGA), Fourier transform infrared (FTIR), Brunauer–Emmett–Teller (BET) and temperature-programmed desorption – ammonia/carbon dioxide (TPD-NH3/CO2). The prepared PET H3PO4 and PET KOH showed the higher surface area, thus illustrating that the surface of both materials has enough space for impregnation of foreign precursors. The TPD-NH3 and TPD-CO2 results depicted that PET H3PO4 is found to have higher acidity, i.e., 18.17 mmolg−1, due to the attachment of phosponyl groups to it during pretreatment, whereas, in the case of PET KOH, the basicity increases to 13.49 mmolg−1. The conversion results show that prepared materials can be used as a support for an acidic and basic catalyst for the conversion of WCO and PFAD into green fuel.

Abstract A precipitation procedure and liquid chromatography (LC) were used to measure the residual reactants and reaction by-products in polyethylene terephthalate (PET) polymers and food packages. The polymer is dissolved in l,l,l,3,3,3-hexafluoro-2-propanol/methyIene chloride and then precipitated with acetone. The filtered solution is evaporated almost to dryness, and the concentrate is diluted with dimethylacetamide for LC analysis. Recoveries for terephthalic acid (TA), bis(2-hydroxyethyl) terephthalate (BHET), and the PET cyclic trimer averaged 95,104, and 98%, respectively. The residual levels of TA, BHET, monohydroxy ethylene terephthalic acid, and the PET cyclic trimer were measured in commercial resins and food packages.
