- Derived from levulin.
GNU Webster's 1913
- adj. (Chem.) Pertaining to, or denoting, an acid (called also
acetyl-propionic acid), C5H8O3, obtained by the action of dilute acids on various sugars (as levulose).
“The new process converts those carbohydrates into chemicals called levulinic acid esters - at the same time and in the same vessel that the oils are converted to fatty acid esters - resulting in a fuel cocktail that performs better at low temperatures than conventional biodiesel.”
“Segetis wants to use a thermochemical process to turn cellulosic biomass into a chemical called levulinic ketal, which can be transformed into a variety of chemicals.”
“However, in previously studied conversion methods, sugar molecules frequently degrade to form levulinic acid and formic acid - two products the previous methods couldn't readily transform into high-energy liquid fuels.”
“Instead of trying to fight the degradation, we started with levulinic acid and formic acid and tried to see what we could do using that as a platform," says Dumesic.”
“Other potential specialty chemical products of cellulose biofuels projects include lactic acid, succinic acid, levulinic acid, and 1,3-propanediol.”
“Similarly, levulinic acid obtained from cellulose cost about 59¢/lb to produce in 2005, the report found, and will likely drop to around 26¢/lb by 2015.”
“These monomers are built from levulinic acid, a chemical derived from cellulosic biomass, and biobased hydroxyl compounds.www. segetis.com.”
“The two papers focus on the compound levulinic acid, which is formed, along with formic acid, when six-carbon sugars are reacted with acids.”
“The levulinic acid can undergo a hydrogenation reaction to form γ-valeroactone (GVL), at which point the two papers diverged.”
“The project focuses on fundamental and spectroscopic studies on the hydrogenation of levulinic acid with heterogeneous catalysts to identify catalyst-product relations which will allow proper selection of catalyst formulation and reaction conditions to obtain the desired hydrogenation product.”
