Versión en Español Type of post: Fact sheet. Series: Biobased chemicals – Organic acids. Publication date: 05/05/2021. Last update: 05/05/2021. Description - Organic acid with 3 carbon atoms. - It is a clear, colourless, corrosive liquid with a characteristic acrid or tart smell. - Other names: prop-2-enoic acid. Applications - Formation of homopolymers or copolymers which are used in the manufacture of various adhesives, coatings, diapers, detergents, paints, plastics and textiles. The main use of crude acrylic acid is the generation of acrylate esters, followed by the production of polyacrylic acid, used mostly in superabsorbent polymers. - Chemical intermediate in multiple industrial processes. Conventional petrochemical route - Cracking of fossil naphtha to produce propylene / Oxidation of propylene. Main biobased routes - [3-HPA via] Fermentation of sugars to produce 3-hydroxypropionic acid (3-HPA) / Dehydration of 3-HPA. - [Biobased naphtha via] Cracking of biobased naphth...

Publication date: 25/04/2016 Last update: 25/04/2016 ABOUT THE SERIES OF POSTS “BIOREFINERY MODELS” This post belongs to a series called “ Biorefinery Models ”. This series is devoted to briefly describe the models or concepts of advanced biorefineries which have emerged in the last few years and that are rising currently. These models are simplified representations which enable us to understand in a simple way the structure and characteristics of a general biorefinery type. Some of these models refer to the type of feedstock while other focus on the technologies involved. A biorefinery may resemble these models or be the result of variations and combinations of them. It should be noted that although these paradigms are very useful and instructive, they show limitations in describing and classifying complex systems with high level of integration. In order to define and describe a specific complex case, the blog recommends use the classification proposed by IEA Bioenerg...

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...

Versión en Español Type of post: Fact sheet. Series: Biobased chemicals – Alcohols. Publication date: 01/06/2021. Last update: 11/06/2021. 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. Conventional petrochemical routes (1) - Reppe process (acetylene): 42% of global capacity. - Davy Process (maleic anhyd...
