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.

IPC: C07C45/41
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.
