标 题:Catalytic synthesis of reduced furan derivatives
发明人：SANBORN ALEXANDRA; BINDER THOMAS P
权利人:ARCHER DANIELS MIDLAND CO
摘要:The present invention relates to catalytic synthesis of furan derivatives from alkoxymethylfurfural ethers or acyloxymethylfurfural esters. More particularly, the invention pertains to furan derivatives obtained by use of a multifunctional catalyst system to carry out both hydrogenation of furan starting material and hydrolysis of the reduced furan derivative in a single reaction. The process allows recovering and recycling of alcohol or acid from the reaction product.

标 题 :Process for the production of esters of levulinic acid from biomasses
发明人：BIANCHI DANIELE; ROMANO ANNA MARIA
权利人:POLIMERI EUROPA S P A SAN DONATO MILANESE
摘要:A new process is described for the direct synthesis of esters of levulinic acid starting from biomasses containing one or more polysaccharides and from aliphatic alcohols, in the presence of a suitable organic acid catalyst. In particular, the biomasses can be lignin-cellulose biomasses. The esters thus obtained can be used as oxygenated components in the formulation of fuels for motor vehicles, with the aim of reducing the particulate emissions.

标 题:Microwave assisted synthesis of dehydrated sugar derivatives hydroxymethylfurfural, levulinic acid, anhydrosugar alcohols, and ethers thereof
发明人：HOWARD STEPHEN J; SANBORN ALEXANDRA J
权利人:HOWARD STEPHEN J; SANBORN ALEXANDRA J; ARCHER DANIELS MIDLAND CO
摘要:Methods for the production of dehydrated sugars and derivatives of dehydrated sugars using microwave (MW) irradiation and methods of purifying the same are described. The dehydrated sugars derivatives include 5-hydroxymethyl-2-furfural (HMF) and anhydrosugar alcohols such as sorbitans and isosorbide. The derivatives include HMF ethers, levulinic acid esters, and ether derivatives of the anhydrosugar alcohols. The described methods require lower reaction temperatures and shorter reaction times than similar non microwave mediated reactions known in the art. Typical reaction conditions are 120-210° C., and typical reaction times are 30 minutes or less.

标 题 :Synthesis of diesel fuel blendstock from carbohydrates
发明人：LOTERO EDGAR; FJARE KRISTI A; PHILLIPS CORY B; PLATON ALEXANDRU
权利人:PHILLIPS 66 CO
摘要:Carbohydrates as derived from plant biomass can be converted into mono-alcohols, diols, and/or bi-functional alcohols or into carboxylic acid derivatives. By catalytic transesterification of such carbohydrate derivatives, ester-type diesel-fuel blendstock components may be produced. More specifically, alkyl levulinates are catalytically trans-esterified with hydroxyl-functionalized compounds where both the alcohols and the alkyl levulinates are derived from biomass carbohydrates. Esters produced in this way show physicochemical characteristics that make them suitable for use as diesel fuel blendstock.
