The starting material is contacted with the catalyst comprising Pt on a support material where the contacting is conducted at a reactor temperature of from about 50° C. to about 200° C. A method of producing an oxidation catalyst where ZrO2 is provided and is calcined. The ZrO2 is mixed with platinum (II) acetylacetonate to form a mixture. The mixture is subjected to rotary evaporation to form a product. The product is calcined and reduced under hydrogen to form an activated product. The activated product is passivated under a flow of 2% O2.Type: GrantFiled: February 24, 2010Date of Patent: June 5, 2012Assignee: Battelle Memorial InstituteInventors: Michael A. Lilga, Richard T.

Publication number: 20120059178Abstract: The disclosure pertains to a process for oxidation of furan aldehydes such as 5-hydroxymethyl)furfural (HMF) and derivatives thereof such as 5-(alkoxymethyl)furfural (AMF), 5-(aryloxymethyl)furfural, 5-(cycloalkoxy-methyl)furfural and 5-(alkoxycarbonyl)furfural compounds in the presence of dissolved oxygen and a Co(II), Mn(II), Ce(III) salt catalyst or mixtures thereof. The products from HMF can be selectively chosen to be predominantly 2,5-diformylfuran (DFF), particularly by inclusion of an aliphatic ketone, like methyl ethyl ketone, or can be further oxidized to 2,5-furandicarboxylic acid (FDCA) by the omission of methyl ethyl ketone and inclusion of bromide. When the reactant is an ether derivative of HMF the products are surprisingly ester derivatives where either both the ether and aldehyde functional groups have been oxidized or just the ether function group thereby producing one or both of 5-ester-furan-2-acids (i.e., 5-alkoxycarbonylfurancarboxylic acids) or 5-ester-furan aldehydes, (i.e.Type: ApplicationFiled: May 14, 2010Publication date: March 8, 2012Applicant: ARCHER DANIELS MIDLAND COMPANYInventor: Alexandra J.

Publication number: 20100317870Abstract: The invention generally relates to novel polymers (SMAMPs) and their syntheses and use. The polymers exhibit promising properties of AMPs. In particularly, for example, a ring-opening metathesis polymerization (ROMP) platform was developed that allows syntheses of SMAMPs that employ a minimum number of norbornene-based building blocks and/or enable easy and independent variation of hydrophobic and hydrophilic groups in the monomer units and/or along the polymeric backbone to finetune and select desirable properties of the polymers.Type: ApplicationFiled: June 8, 2010Publication date: December 16, 2010Inventors: Gregory Tew, Ahmad E.

Patent number: 7411078Abstract: A method for producing furan-2,5-dicarboxylic acid (FDCA) is provided which can efficiently and quantitatively producing FDCA under mild conditions, without employing an expensive catalyst and with a reduced energy consumption. A furan ring compound having two functional groups selected from a hydroxymethyl group, a formyl group and a carboxyl group in the 2- and 5-positions of the furan ring, is oxidized with a metal permanganate in an alkaline environment to produce furan-2,5-dicarboxylic acid. Advantageously, the alkaline environment contains at least one of alkali metal hydroxides and alkali earth metal hydroxides, and the oxidation is performed at a temperature of from 1 to 50° C. by adding the permanganate metal salt to the alkaline aqueous solution containing the furan ring compound.Type: GrantFiled: March 7, 2007Date of Patent: August 12, 2008Assignee: Canon Kabushiki KaishaInventors: Toshinari Miura, Hirokazu Kakinuma, Takenobu Kawano, Hirohide Matsuhisa
