Abstract
Ion exchange membrane divided electrochemical cells with a system of separated heterogeneous aqueous/nonaqueous electrolytes provide improved performance in both energy consuming and energy producing electrochemical processes by more effectively restricting the transmission of neutral molecules between cell compartments and by isolating reactions occuring at the working and counter electrodes.
Claims9
A method for organic electrosynthesis comprising the steps of providing an electrolytic cell having an anode in an anode compartment, a cathode in a cathode compartment and a permselective membrane spaced from said anode and cathode;
- introducing into said anode compartment an anolyte comprising a nonaqueous solvent, a sufficiently soluble current conducting salt and an oxidizable organic compound;
- introducing into said cathode compartment a catholyte comprising an aqueous solvent, and impressing a voltage across said anode and cathode to oxidize said organic compound at the anode.
