  • Electrochemical method for preparing an amine and/or a nitrile
    Patent number: 11866835
    Abstract: The present invention relates to an electrochemical method for converting an amino acid and/or its salts to an amine and/or a nitrile. The total yield and selectivity of amine and nitrile obtained by the method according to the present invention is higher than prior art when the reaction medium has a high concentration of amino acid and/or its salts at the beginning of the reaction.
    Type: Grant
    Filed: November 25, 2019
    Date of Patent: January 9, 2024
    Assignee: RHODIA OPERATIONS
    Inventors: Renate Schwiedernoch, Fan Jiang, Stephane Streiff, Pascal Metivier, Dominique Horbez
  • AN ELECTROCHEMICAL METHOD FOR PREPARING VANILLIN OR ITS DERIVATIVES
    Publication number: 20230022284
    Abstract: The present invention relates to an electrochemical method for preparing vanillin or its derivatives in the presence of a mediator. The mediator can be recycled and reused and therefore no salt is formed by the end of the reaction, which makes the method more environmental-friendly. Furthermore, lower potentials are needed when the mediator is used by comparing to prior arts.
