Hydrogenation Of Aliphatic Nitriles To Primary Amines
View pageUS Patent:
42358213, Nov 25, 1980
Filed:
Feb 1, 1979
Appl. No.:
6/008315
Inventors:
Walter A. Butte - West Chester PA
William J. Murtaugh - Eddystone PA
Richard E. Mitchell - Glenmills PA
William J. Murtaugh - Eddystone PA
Richard E. Mitchell - Glenmills PA
Assignee:
Suntech, Inc. - Philadelphia PA
International Classification:
C07C 8714
C07C 8512
C07C 8512
US Classification:
564491
Abstract:
In the process of hydrogenating aliphatic nitriles to primary amines whereby the nitrile is hydrogenated in a solvent system containing added ammonia using a cobalt or ruthenium catalyst, the improvement of employing an ether as solvent and carrying out the hydrogenation in the presence of water in an amount of from about 5% to about 15% by volume of the ether solvent whereby the rate of reaction is increased, and selectivity to primary amine products is increased.
Process For Hydrogenating Aromatic Dinitriles
View pageUS Patent:
42229618, Sep 16, 1980
Filed:
Feb 1, 1979
Appl. No.:
6/008313
Inventors:
Walter A. Butte - West Chester PA
William J. Murtaugh - Eddystone PA
Howard P. Angstadt - Media PA
William J. Murtaugh - Eddystone PA
Howard P. Angstadt - Media PA
Assignee:
Suntech, Inc. - Philadelphia PA
International Classification:
C07C 8500
US Classification:
260563D
Abstract:
A process for the hydrogenation of aromatic dinitriles to the corresponding cycloaliphatic aminomethyl compounds by (1) hydrogenating the nitrile in an ether solvent containing water and ammonia using nickel or cobalt as catalyst, (2) removing by-products from the aromatic diamine thus produced, (3) subjecting the aromatic diamine to hydrogenation with a ruthenium catalyst in an aqueous solvent system devoid of ammonia and (4) isolating the cycloaliphatic diamine product.
Hydrogenation Of Phthalonitriles Using Rhodium Catalyst
View pageUS Patent:
39988813, Dec 21, 1976
Filed:
Nov 13, 1974
Appl. No.:
5/523298
Inventors:
Walter Albert Butte - West Chester PA
William J. Murtaugh - Eddystone PA
William J. Murtaugh - Eddystone PA
Assignee:
Sun Ventures, Inc. - St. Davids PA
International Classification:
C07C 8502
US Classification:
260563R
Abstract:
A process for the preparation of 1,3 or 1,4-bis (aminomethyl)cyclohexane by hydrogenating a solvent solution of iso- or terephthalonitrile at a temperature between about 50. degree. and about 150. degree. C. , at a pressure of between about 500 and about 1500 psig. , and in the presence of a supported rhodium catalyst.
Hydrogenation Of Aromatic Nitriles To Primary Amines
View pageUS Patent:
41861469, Jan 29, 1980
Filed:
Feb 1, 1979
Appl. No.:
6/008310
Inventors:
Walter A. Butte - West Chester PA
William J. Murtaugh - Eddystone PA
William J. Murtaugh - Eddystone PA
Assignee:
Suntech, Inc. - Philadelphia PA
International Classification:
C07C 8512
US Classification:
2605705P
Abstract:
In the process of hydrogenating aromatic nitriles to primary amines whereby the nitrile is hydrogenated in a solvent system containing added ammonia using a cobalt or nickel catalyst, the improvement of employing an ether as solvent and carrying out the hydrogenation in the presence of water in an amount of from about 10% to about 20% by volume of the ether solvent whereby the rate of reaction is increased, secondary amine by-products are reduced and catalyst may be recycled without adverse effects.
