Mono- or dimethylol compounds having water solubilities of 3 grams or less per 100 grams of water are electrochemically oxidized to the corresponding mono- or dicarboxylic acids at activated nickel oxide anodes. The methylol compounds are adducts of 1,2-alkylene oxides with phenols, pyridinols, bisphenols, phenoxy- or pyridinyloxypyridinols or are polycycloaliphatics ring-substituted with one or two CH.sub.2 OH groups.

Oxidation of hydrophobic --CH.sub.2 OH compounds at oxidized nickel

Electrolytic reduction of tetrachloro-2-picolinic acid in basic aqueous solution, at an activated silver cathode, yields the 3,4,6- and 3,5,6-trichloro-2-picolinic acids, which in turn may be further reduced to 3,6-dichloropicolinic acid, a highly active herbicide.

Electrolytic production of certain trichloropicolinic acids and/or
