Fecha de publicación: 16/11/2015 Última actualización: 20/02/2016 Descripción 1,2 El ácido levulínico (también conocido como ácido 4-oxopentanoico o ácido γ-cetovalérico) es un compuesto orgánico con fórmula química C 5 H 8 O 3 . Es un sólido cristalino soluble en agua y en disolventes orgánicos polares. Contiene un grupo cetona y un grupo carboxilo cuya presencia posibilita patrones reactivos interesantes. Es uno de los “ Biobased Chemical Building Blocks ” más reconocidos, precursor de un amplio número de compuestos (véase el apartado Aplicaciones más abajo). De hecho, fue reconocido por el DoE como una de las principales moléculas plataforma del futuro y puede cubrir de manera eficaz muchas de las atribuciones de productos químicos y materiales procedentes del petróleo. Tecnologías de proceso 1,3,4,5 La degradación controlada de azúcares C6 mediante ácidos es el proceso más usado para preparar ácido levulínico a partir de biomasa lignocelulósica. Se han estu

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

Alcohol-To-Fuel

Type of post: OVERVIEW. Introduction Bioethanol produced from fermentation of sugar based crops is the major product of the biofuels industry [1]. But, ethanol is not a “drop-in” solution and requires substantial changes in refining or distribution infrastructure. The properties of this alcohol (an oxygenated single molecule) are largely different than those of gasoline, diesel and jet fuel blendstocks (mixtures of hydrocarbons), leading to problems in blends. Ethanol can cause corrosion problems in transport pipelines that were designed to work only with gasoline. In the specific case of the aviation fuel, there are stricter quality requirements than fuels used in road transport. Ethanol shows low compatibility as a blendstock for aviation fuel because of its high volatility and water absorption and low flash point and energy density. Butanol is not as incompatible as ethanol, however, it still poses unacceptable safety risks due to its low flash point and high volatilit
