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.
Claims8
An electrolytic cell useful in the selective replacement of chlorine in organochlorine compounds with hydrogen, which cell comprises an anode having as its surface an alloy comprising essentially about 40 to about 70 percent nickel, about 5 to about 30 percent chromium, and about 3 to about 25 percent molybdenum and a cathode having a silver surface.
An electrolytic cell useful in the selective replacement of chlorine in organochlorine compounds with hydrogen, which cell comprises an anode having as its surface an alloy comprising approximately 55 percent nickel, 16 percent chromium, 16 percent molybdenum, 5 percet iron, 4 percent tungsten, 2.5 percent cobalt, and 1 percent manganese and a cathode having a silver surface.
