Inventors:

Fred Y. Edamura - Concord CA
Assignee:

The Dow Chemical Company - Midland MI
International Classification:

A01N 922
US Classification:

424250

US Patent:

44964404, Jan 29, 1985
Filed:

Jun 4, 1984
Appl. No.:

6/617063
Inventors:

Kent D. Campbell - Concord CA
Aylin H. Gulbenkian - Walnut Creek CA
Fred Y. Edamura - Concord CA
Demetrios Kyriacou - Salonica, GR
Assignee:

The Dow Chemical Company - Midland MI
International Classification:

C25B 302
US Classification:

204 78
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.

US Patent:

42171857, Aug 12, 1980
Filed:

Jul 2, 1979
Appl. No.:

6/054130
Inventors:

Demetrios Kyriacou - Clayton CA
Fred Y. Edamura - Concord CA
Jim Love - Walnut Creek CA
Assignee:

The Dow Chemical Company - Midland MI
International Classification:

C25B 304
C25B 1104
US Classification:

204 73R
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.
