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...

Type of post: NEWS. Praj Industries has announced that its Enfinity technology will be deployed to produce ethanol and other co-products in what would be USA’s first sugarcane bagasse based biorefinery. Press release: “ Praj’s 2G Ethanol Technology for USA’s First Ever Bagasse-based Bio-Refinery ”, 3/9/2019. Figure 1. The feedstock of the biorefinery promoted by Omega Energy USA and Lasuca Sugar will be sugarcane bagasse The biorefinery is being jointly promoted by Omega Energy USA (a developer of renewable energy projects headquartered in Florida) and Lasuca Sugar (a producer of cane sugar based in Louisiana). The second one will supply bagasse feedstock. The promoters have issued a formal letter confirming their interest to engage Praj for developing the design and project program for a cellulosic ethanol biorefinery in USA. Lasuca and Omega Energy are in the process of completing necessary formalities for the project. Location Cane-sugar belt o...

English version Tipo de entrada: Hoja de datos. Serie: Productos químicos biobasados – Ácido orgánicos. Fecha de publicación: 25/05/2021. Última actualización: 25/05/2021. Descripción - Ácido dicarboxílico alifático C6. - Polvo cristalino blanco. - Otros nombres: ácido hexanodioico; Ácido 1,4-butanodicarbocílico. Aplicaciones - Monómero para la producción de nailon 6,6. - Monómero para la producción de poliuretano. - Fabricación de plastificantes y lubricantes. - Agente gelificante y acidulante (grado alimenticio). Ruta petroquímica convencional - Oxidación de ciclohexano para producir aceite KA (mezcla de ciclohexanona y ciclohexanol) / Oxidación con ácido nítrico del aceite KA. Durante la reacción final, se forma un potente gas de invernadero, el óxido nitroso (N2O, 300 veces más potente que el dióxido de carbono). Se ha estimado que la sustitución del proceso petroquímico actual por uno que emplee precursores renovables reducirá las emisiones de gases de efecto invernadero hasta ...

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...

Profile: DADTCO – Small-scale processing for the cassava revolution in Africa

By
Image
Introduction The Blog has recently launched a new section about small-scale biorefining , a platform to promote small-sized biorefinery concepts and highlight their importance for the bioeconomy (it is complemented by a LinkedIn Group to share information and experiences). One of the resources available in the section is a list with references of companies and projects related to this field. This list will include a short overview and a link to a monographic post (profile) featuring in detail the company or the project. This post about Dutch AgriculturalDevelopment & Trading Company BV (DADTCO) is the first of the series. The company Web page: https://dadtco-philafrica.com/ . Twitter: @dadtconl. Facebook: Dadtco. DADTCO is a social enterprise pursuing poverty alleviation with entrepreneurial zeal, business methods and innovative courage. It was established in The Netherlands in 2002. It has its support office in that country and local offices in Nigeria, Mo...
