Cathodic hydrogen evolution is the counterreaction to anodic chlorine evolution. It is expected to be superseded by the energy-saving cathodic oxygen reduction (61) only after a decade of further development and only if energy prices continue to increase.

ADCT includes increased active area. Advanced technology cathodes (ATC ), Energy saving anodes (ESAtM), Polyramix diaphragms, zero-gap operation, titanium base covers (Tibac ) and Telene ... 

The introduction of Dimensionally Stable Anodes (DSA ) in the beginning of the 1970s [6] resulted in about 10 % energy saving. Titanium is used as a carrier metal which is corrosion resistant due to a passivation layer of titanium dioxide, stabilized by the oxidation potential of chlorine in aqueous solution. 

Adipodinitrile is an intermediate for hexamethylenediamine, the amine component of nylon 66. The electrochemical process is economically superior to the synthesis of adipodinitrile from cyclohexanone. Today, it essentially competes with the addition reaction of HCN to butadiene. The total capacity of the electrochemical ADN synthesis is currently about 250,000 tonnes/year. The process is industrially fully developed. Recent work 34 347) is aimed at reducing the oxygen evolution potential at the anode in order to save further energy.
