Abstract
Nickel alloy anodes are suitable for electrochemical cells that are used for the selective replacement of chlorine in organochlorine compounds with hydrogen and are resistant to corrosion. Electrochemical cells containing Hastalloy C-276 anodes and silver cathodes, for example, are used to convert tetrachloropicolinic acid to 3,6-dichloropicolinic acid.
