Abstract
The person invention relates to a method for the electro-decarboxylation of at least one diene with carbon dioxide COin the presence of hydrogen H, forming at least one unsaturated dicarboxylic acid, wherein the reaction is carried out in a reactor comprising at least one cathode as the working electrode for the cathodic activation of CO, at least one anode as the counterelectrode for the anodic oxidation of H, with a volumetric ration of hydrogen Hto carbon dioxide CObetween 1:1 and 1:3, a total pressure pg in the reactor between 2 and 4 MPa, particularly preferably between 3 and 4 MPa, and an average current density j between 5 and 15 mA/cm, particularly preferably between 10 and 12.5 mA/cm.
