US Patent:

RE313564, Aug 23, 1983
Filed:

Feb 26, 1981
Appl. No.:

6/238395
Inventors:

Clarence E. Habermann - Midland MI
Ben A. Tefertiller - Midland MI
Assignee:

The Dow Chemical Co. - Midland MI
International Classification:

C07C10300
US Classification:

564127
Abstract:

[. Aliphatic nitriles. ]. . Iadd. Olefinic nitriles of three to six carbon atoms. Iaddend. are converted to the corresponding amides by contacting the nitrile in the presence of water with a cupreous catalyst containing copper prepared by reducing copper hydroxide or a copper salt.

US Patent:

39912566, Nov 9, 1976
Filed:

Dec 27, 1974
Appl. No.:

5/537044
Inventors:

Sally P. Cornier - Sanford MI
Ben A. Tefertiller - Midland MI
Richard J. Dolinski - Midland MI
Assignee:

The Dow Chemical Company - Midland MI
International Classification:

B32B 2710
B05D 512
B05D 302
US Classification:

428514
Abstract:

An improved electroconductive resin composition is obtained by using a water-dispersible, film-forming acrylamide polymer as a binder and extender for a water-soluble quaternary ammonium electroconductive resin. Particularly useful is a self-binding blend of about 65-95 wt. % polyvinylbenzyltrimethylammonium chloride and about 5-35 wt. % nonhydrolyzed polyacrylamide which can be formulated as an aqueous dispersion with clay or other printing pigments. Applied to a nonmetallic substrate, such as paper or an organic polymer film, the improved electroconductive resin composition reduces the surface electrical resistivity of the substrate and also provides improved holdout to aromatic and aliphatic solvents.

Ralph E. Friedrich - Midland MI
Assignee:

The Dow Chemical Company - Midland MI
International Classification:

C07C10308
US Classification:

564128
Abstract:

Aliphatic nitriles are converted to the corresponding amides by contacting the nitrile in the presence of water with a cupreous catalyst containing copper metal.

US Patent:

39949737, Nov 30, 1976
Filed:

Jun 28, 1971
Appl. No.:

4/157647
Inventors:

Clarence E. Habermann - Midland MI
Ben A. Tefertiller - Midland MI
Assignee:

The Dow Chemical Company - Midland MI
International Classification:

C07C10356
US Classification:

260561N
Abstract:

Cupreous catalysts containing (a) copper prepared by reducing copper oxide, (b) reduced copper oxide, or (c) copper oxide have been found to be excellent heterogeneous catalysts for the conversion of nitriles in the presence of water to the corresponding amides. High conversions and yields are obtained with little or no deleterious by-products.

Filed:

Feb 26, 1981
Appl. No.:

6/238712
Inventors:

Clarence E. Habermann - Midland MI
Ben A. Tefertiller - Midland MI
Assignee:

The Dow Chemical Co. - Midland MI
International Classification:

C07C10300
US Classification:

564127
Abstract:

Copper, copper oxide, copper-chromium oxide, copper-molybdenum oxide or mixtures thereof have been found to be excellent heterogeneous catalysts for the conversion of nitriles in the presence of water to the corresponding amides. Using one such catalyst in a continuous flow reactor, acrylonitrile was almost 100% converted to acrylamide during more than six weeks of continuous operation.
