Poly ethylene 2 5-furandicarboxylate

WebJan 19, 2024 · 2,5-Furandicarboxylic acid (2,5-FDCA) has been regarded as the ideal bio-based alternative to terephthalic acid (TPA). In recent years, great efforts have been made to synthesize 2,5-FDCA through the following methods: (1) oxidation of 5-hydroxymethylfurfural (HMF) in the presence of complex biocatalyst or metallic catalyst; (2) conversion of 2 … Polyethylene furan-2,5-dicarboxylate, also named poly(ethylene furan-2,5-dicarboxylate), polyethylene furanoate and poly(ethylene furanoate) and generally abbreviated as PEF, is a polymer that can be produced by polycondensation or ring-opening polymerization of 2,5-furandicarboxylic acid (FDCA) and ethylene glycol. As an aromatic polyester from ethylene glycol it is a chemical analogue of polyethylene terephthalate (PET) and polyethylene naphthalate (PEN). P…
