  • Method and integrated process for the carboxylation of furan derived carboxylic acids to 2,5-furandicarboxylic acid
    Patent number: 11708343
    Abstract: A process for carboxylation of a furoate slurry to produce FDCA, especially 2,5-FDCA, includes the steps of: feeding a slurry containing a suspension fluid, furoate, a surfactant and an alkali metal carbonate to a carboxylation reactor; and feeding a flow of CO2 to the carboxylation reactor at flow conditions sufficient to suspend the slurry in the reactor and react the furoate with CO2 to form 2,5-FDCA. A fully integrated process is also disclosed.
    Type: Grant
    Filed: July 16, 2021
    Date of Patent: July 25, 2023
    Assignee: KSE, Inc.
    Inventors: James R. Kittrell, Carl R. Dupre, Keith D. Kittrell, Leonard T. McDonald, Jeffrey A. Kittrell
