  • Oxidation of hydrophobic --CH.sub.2 OH compounds at oxidized nickel anodes
    Patent number: 4496440
    Abstract: 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.
    Type: Grant
    Filed: June 4, 1984
    Date of Patent: January 29, 1985
    Assignee: The Dow Chemical Company
    Inventors: Kent D. Campbell, Aylin H. Gulbenkian, Fred Y. Edamura, Demetrios Kyriacou
  • Electrolytic production of certain trichloropicolinic acids and/or 3,6-dichloropicolinic acid
    Patent number: 4217185
    Abstract: 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.
    Type: Grant

    Patent number: 3966937
    Abstract: Methyl-(4-methylphenyl)-substituted-tetrazolo-(1,5-a)pyrimidine and methods employing the same for the systemic protection of plants from soil-borne plant disease organisms.
    Type: Grant
    Filed: January 20, 1975
    Date of Patent: June 29, 1976
    Assignee: The Dow Chemical Company
    Inventors: Fred Y. Edamura, Ronald J. Sbragia
  • 6-(Substituted phenoxy)tetrazolo(1,5-b)pyridazines and a method of use for control of soil-borne plant diseases
    Patent number: 3961059
    Abstract: Disclosed are novel 6-(substituted phenoxy)-tetrazolo(1,5-b)pyridazine compounds and methods employing the same for protecting plants from soil-borne disease both prior to infection and after infection by systemically killing and controlling the disease organisms.
