Organic synthesis of titanium anode - baoji ZhiMing titanium anode electrode

By electrolysis oxidation reduction reactions of organic compounds, and producing new organic electrolytic synthesis is the process by which organic matter, also known as organic electrochemistry. Organic electrolytic synthesis has the following features: do not use reaction reagent, can under atmospheric pressure conditions, usually do not need to heating, cooling, pollution-free, no discharge of three wastes, the reaction speed is easy to control, midway can pause. In electrolytic organic synthesis, the choice of cathode materials, the electrode is the work electrode or electrode should be considered. When reaction in aqueous solution of living water mixed medium, the electrode as work electrode, which rely on the cathodic reduction reaction product, should choose the materials with high hydrogen evolution over potential, such as lead, zinc, mercury. But if you would like to produce electrochemical hydrogenation reaction, namely the need to produce H2 at the cathode surface, and then hydrogenation reaction with organic molecules, the low hydrogen evolution over potential of the electrode materials should be adopted, such as platinum, nickel, and iron. When used as a counter electrode, cathode, organic synthesis reactions that appears at the anode and cathode when only as auxiliary electrode, cathode H2 evolution reaction into is given priority to, at this time should be used in low hydrogen evolution over potential of the electrode materials. Electrolysis in organic synthesis, the choice of the anode materials is very difficult, because at the anode electrode polarization, the dissolution and corrosion can occur. According to the different electrolyte, can use the following anode material, the Pt - Ir, graphite, DSA (Ti/RuO2, Ti/Cr2O3), lead, also can choose platinum, titanium, platinum plating, lead dioxide plating titanium, titanium iridium high oxygen potential titanium titanium anode electrode.
