  • Methods of producing para-xylene and terephthalic acid
    Patent number: 10392317
    Abstract: The present disclosure provides methods to produce para-xylene, toluene, and other compounds from renewable sources (e.g., cellulose, hemicellulose, starch, sugar) and ethylene in the presence of a catalyst. For example, cellulose and/or hemicellulose may be converted into 2,5-dimethylfuran (DMF), which may be converted into para-xylene by cycloaddition of ethylene to DMF. Para-xylene can then be oxidized to form terephthalic acid.

  • Methods of producing para-xylene and terephthalic acid
    Patent number: 9890101
    Abstract: The present disclosure provides methods to produce para-xylene, toluene, and other compounds from renewable sources (e.g., cellulose, hemicellulose) and ethylene in the presence of an acid, such as a Lewis acid. For example, cellulose and/or hemicellulose may be converted into 2,5-dimethylfuran (DMF) and 2-methylfuran, which may be converted into para-xylene and toluene, respectively. In particular, para-xylene can then be oxidized to form terephthalic acid.

  • Methods of producing alkylfurans
    Patent number: 9840486
    Abstract: Provided herein are methods of producing dialkylfurans, such as 2,5-dimethylfuran, and other alkyl furans, such as 2-methylfuran. For example, 2,5-dimethylfuran may be produced by hydrogenation of (5-methylfuran-2-yl) methanol or 2-(chloromethyl)-5-methylfuran in the presence of a solid supported metal catalyst having an excess of either basic or acidic sites (as determined by chemisorption of CO2 or NH3). The process could further include a urea reagent (TMU, DMPU, TMI) and an alkyl benzene.
