Catalyst Passivation In Production Of Amines
US Patent:
4359585, Nov 16, 1982
Filed:
Apr 21, 1980
Appl. No.:
6/141836
Inventors:
Charles R. Campbell - Pensacola FL
Charles E. Cutchens - Decatur AL
Charles E. Cutchens - Decatur AL
Assignee:
Monsanto Company - St. Louis MO
International Classification:
C07C 8512
US Classification:
564492
Abstract:
This is an improvement in a process for the production of an amine such as hexamethylenediamine from a nitrile such as adiponitrile where the nitrile is hydrogenated under pressure in the presence of a Raney nickel catalyst, the reaction being conducted in a reactor from which is discharged a product stream containing both the amine and the Raney nickel catalyst. The improvement comprises charging to the process discharge stream containing the product amine and the Raney nickel catalyst, an inorganic base, whereby the Raney nickel catalyst is passivated and catalytic decomposition of the amine is substantially decreased.
Oxidative Dehydrogenation Of Propionitrile To Acrylonitrile
US Patent:
4178305, Dec 11, 1979
Filed:
Oct 23, 1978
Appl. No.:
5/953984
Inventors:
Charles R. Campbell - Pensacola FL
William A. Heckle - Pensacola FL
Marion J. Mathews - Pensacola FL
William A. Heckle - Pensacola FL
Marion J. Mathews - Pensacola FL
Assignee:
Monsanto Company - St. Louis MO
International Classification:
C07C12000, C07C12132
US Classification:
2604659
Abstract:
Propionitrile is subject to oxidative dehydrogenation at high temperatures in the presence of a stoichiometric excess of a metal oxide oxygen donor to produce acrylonitrile at a high rate of conversion and selectivity.
Catalyst Passivation In Production Of Amines
US Patent:
4247481, Jan 27, 1981
Filed:
Dec 26, 1979
Appl. No.:
6/106587
Inventors:
Charles R. Campbell - Pensacola FL
Charles E. Cutchens - Decatur AL
Charles E. Cutchens - Decatur AL
Assignee:
Monsanto Company - St. Louis MO
International Classification:
C07C 8512, C07C 8511, C07C 8526
US Classification:
564492
Abstract:
This is an improvement in a process for the production of an amine such as hexamethylenediamine from a nitrile such as adiponitrile where the nitrile is hydrogenated under pressure in the presence of a Raney nickel catalyst, the reaction being conducted in a reactor from which is discharged a product stream containing both the amine and the Raney nickel catalyst. The improvement comprises charging to the process discharge stream containing the product amine and the Raney nickel catalyst, a nitroaromatic compound, whereby the Raney nickel catalyst is passivated and catalytic decomposition of the amine is substantially decreased.
Semi-Continuous Electro-Hydrodimerization Of Acrylonitrile To Adiponitrile With Replating Of Cathode
US Patent:
4155818, May 22, 1979
Filed:
Jul 17, 1978
Appl. No.:
5/925012
Inventors:
Charles R. Campbell - Pensacola FL
William A. Heckle - Pensacola FL
Marion J. Mathews - Pensacola FL
William A. Heckle - Pensacola FL
Marion J. Mathews - Pensacola FL
Assignee:
Monsanto Company - St. Louis MO
International Classification:
C25B 310, C25B 1104, C25B 1102, C25D 534
US Classification:
204 73A
Abstract:
An improvement in the process of electrohydrodimerizing acrylonitrile to adiponitrile wherein the plated electrodes, which are employed in the process as a part of an electrolytic cell, are, without removal from the cell, cleaned and replated.
Electroplating Cathodes For Electrochemical Synthesis
US Patent:
4203808, May 20, 1980
Filed:
Jul 14, 1976
Appl. No.:
5/705307
Inventors:
Charles R. Campbell - Pensacola FL
William A. Heckle - Pensacola FL
Marion J. Mathews - Pensacola FL
William A. Heckle - Pensacola FL
Marion J. Mathews - Pensacola FL
Assignee:
Monsanto Company - St. Louis MO
International Classification:
C25D 500, C25D 2100
US Classification:
204 23
Abstract:
Packages of undivided electrolytic cells for electrochemical synthesis having a plurality of metal-plated cathodes with corresponding anodes are produced by assembling and permanently fixing the electrodes in substantially parallel-planar relationship as a package and thereafter electroplating the cathodes in package form by applying an electric potential between the anodes and cathodes in an electroplating solution containing the plating metal in complex form, the anodes functioning as non-sacrificial anodes during electroplating. Such electroplating may be accomplished in the electrochemical synthesis cells and may employ the same power application means and controls as the means and controls employed in the electrochemical synthesis.
Process For Hydrodimerizing Olefinic Compounds
US Patent:
3960679, Jun 1, 1976
Filed:
Jun 27, 1975
Appl. No.:
5/591181
Inventors:
Charles R. Campbell - Pensacola FL

Assignee:
Monsanto Company - St. Louis MO
International Classification:
C25B 310, C07C12126, C07C103147, C07C 6934
US Classification:
204 73A
Abstract:
In a process for hydrodimerizing an olefinic nitrile, amide or ester by electrolyzing an aqueous solution of the olefinic compound, alkali metal salt and quaternary ammonium or phosphonium cations, the selectivity with which the hydrodimer is produced is surprisingly high when the solution contains less than about 5% by weight of the olefinic compound and alkali metal cations constituting more than half of the total weight of all cations in the solution and the solution is electrolyzed in contact with a cathode consisting essentially of cadmium.
