Abstract
An important increase in the yield of 3,6-dichloropicolinic acid prepared by electrolytic reduction of tetrachloro-2-picolinic acid (in basic, aqueous solution, at a silver cathode) results when a stainless steel anode is used, rather than those (graphite, e.g.) taught in the prior art (U.S. Pat. No. 4,217,185).
