Publication date: 14/12/2015 Last update: 24/05/2017 Description 1,2,3,4 D-Glucaric acid, also called saccharic acid, is a chemical compound with formula C 6 H 10 O 8 and member of a large family of molecules known as oxidized sugars. It is a naturally occurring aldaric acid, typically found in small amounts in a variety of fruits and vegetables. It is a highly functionalized compound with four chiral carbons and a plethora of reaction pathways. Its commercial potential was unveiled in the report “Top Value Added Chemicals from Biomass” from the Department of Energy of USA which described its use as a building block for a number of polymers, including new nylons and hyperbranched polyesters. Process technologies 1,3,4,5,6,7,8 The synthetic preparation of D-glucaric acid dates back to a report of Sohst and Tollens (1888) who carried out the nitric acid oxidation of D-glucose to D-glucaric acid. Current methods for its production are based on this process and in...

Description - Diol with 4 carbon atoms. - It is a colourless, viscous liquid. Applications - In the presence of phosphoric acid and high temperature, it dehydrates to the tetrahydrofuran (THF), which is used in various industrial applications such as a solvent in pharmaceuticals. Half of the BDO consumption is used for production of THF. - The second largest market for BDO is the synthesis of γ-butyrolactone (GBL). GBL is used in industrial cleaning products and in the production of Methylpyrrolidone (NMP) and 2-pyrrolidone. - Polybutylene terephthalate (PBT) is produced by polymerising terephthalic acid and BDO. PBT is an engineering plastic is used in a wide range of applications, mainly in electrical and automotive component.
