Avantium Chemistry (www.avantium.com) explores novel furan (YXY) chemistry, focused on efficient and low cost conversion of C6 sugars into derivatives of the promising chemical key intermediate hydroxymethyl furfural (HMF) in the presence of a homogeneous or solid acid catalyst. For more than a century, HMF has been seen as the “sleeping giant, a key substance between carbohydrate chemistry and mineral oil-based industrial chemistry”, guarding the large application potential for furan based products. HMF can be produced from monosaccharides such as fructose and glucose by acid catalyzed elimination of 3 molecules of water. Avantium is developing a breakthrough technology to convert biomass into Furanics from carbohydrates. HMF derivatives can now be obtained in high yields from hexose (sucrose, starch or cellulose) or cheap(er) raw materials which contain mixtures of pentoses and hexoses such as waste streams and lignocellulosics, and make very interesting building blocks for biopolymers. The most interesting building block for polymers derived from HMF/MMF is a molecule called FuranDiCarboxylic Acid, abbreviated FDCA. FDCA can be used as building block for a wide range of applications including polyesters, polyamides, resins and plasticizers. In this presentation particular attention will be given to the improved technical properties of the biobased polyester PEF compared to PET for bottle, fibre and film applications. Avantium’s proprietary technology is all based upon catalytic chemical processes. The focus will be on the potential benefits of PEF for a variety of industrial applications.
