New method could enable high-yield biobased plastic bottle production

Scientists from Hokkaido University in Japan and Eindhoven University of Technology in the Netherlands found that furan-2.5 dicarboxylic acid can be synthesized with a high yield from a glucose derivative of non-food plant cellulose by acetalizing hydroxymethylfurfural with 1.3-propanediol and oxidizing HMF-acetal with a supported gold catalyst. The researchers, who reported their findings in the journal Angewandte Chemie International Edition, said the method helps replace petroleum-derived terephthalic acid with biomaterials in plastic bottle production.
