  • 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.
    Type: Grant
    Filed: September 13, 2013
    Date of Patent: August 27, 2019
    Assignee: MICROMIDAS, INC.
    Inventors: Makoto N. Masuno, Ryan L. Smith, John Bissell, II, Patrick B. Smith, Dennis A. Hucul, Edmund J. Stark, Daniel R. Henton, Adina Dumitrascu, Katherine Brune, Dimitri A. Hirsch-Weil

  • 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.
