DEVICE AND METHOD FOR ELECTROCHEMICALLY SYNTHESIZING INTERMEDIATE SPECIES OF A CHEMICAL ENTITY

摘要

The device for electrochemically synthesizing intermediate species of a chemical entity which comprises an electrochemical oxidation cell including a first working electrode and a first counter electrode, capable, when these first electrodes are subject to an electric potential, of generating the intermediate species by oxidation of a solution introduced into the electrochemical oxidation cell and comprising the chemical entity, and an electrochemical stabilization cell including a second working electrode and a second counter electrode respectively distinct from the first working electrode and counter electrode, capable, when these second electrodes are subject to an electric potential, of achieving reduction of a solution. The stabilization cell is connected in series to the oxidation cell so as to allow continuous reduction of the intermediate species generated in the oxidation cell. Applications can be in the pharmaceutical, agri-food and environment fields.

1. A device for synthesizing intermediate species of a chemical entity electrochemically, comprising an electrochemical oxidation cell including at least one first working electrode and a first counter-electrode, and being capable, when said first working electrode and counter-electrode are subject to an electric potential, of generating said intermediate species by oxidation of a solution introduced into said electrochemical oxidation cell and comprising said chemical entity, said device also comprising an electrochemical stabilization cell including at least one second working electrode and a second counter-electrode, and being capable, when said second working electrode and counter-electrode are subject to an electric potential, of achieving reduction of a solution, this said electrochemical stabilization cell being connected in series to the electrochemical oxidation cell,
the first working electrode and counter-electrode are positioned substantially parallel with respect to each other, and maintained spaced apart from each other by means of a first spacer element, so as to each have a surface facing each other, and the second working electrode and counter-electrode are respectively distinct from the first working electrode and counter-electrode, so as to allow continuous reduction in the electrochemical stabilization cell of the intermediate species generated in the electrochemical oxidation cell by scanning, in a given window of potentials, electric potentials applied to the first working electrode and counter-electrode.
