Abstract:Electro-organic processes typically contain complex reaction sequences which couple the heterogeneous electrode reactions with an extended homogeneous reaction pathway. An experimental - theoretical approach was applied to understand the coupled diffusion-reaction processes and establish general criteria for chemistry selection, reactor design and process strategy.
Primary investigation is directed towards paired pathways containing both oxidation and reduction reactions in undivided cells. Galvanostatic processes obtain increased current effiency, selectivity and production rates by controlling mass transfer, species concentrations, and relative mass fluxes. The "standard" galvanostatic process was contrasted with an alternating current process strategy. Alternating Current processes can provide further increases in selectivity with decreases in investment costs by elimination of rectification costs. Alternating current syntheses can be performed with reaction sequences having rapid homogeneous reactions following the electrochemical reaction or gas evolution accompanying the electrochemical reaction. Experimental verification was obtained with propylene oxide synthesis as a model system.
