Abstract
A process for preparing amines or imines which comprises contacting an alcohol, aldehyde, or ketone with an aminating agent in the presence of a catalyst under reaction conditions sufficient to form an amine or imine, wherein the catalyst comprises a homogeneous mixture of (a) 10-90 mole percent cobalt or an insoluble salt thereof, (b) 9-89 mole percent copper or an insoluble salt thereof, and (c) 1-20 mole percent of a metal or insoluble salt of a metal selected from the group consisting of a Lanthanum series metal, thorium, uranium, scandium, titanium, and yttrium is described. A process which employs zirconium as component (c) and which is supported on a carrier material, wherein the carrier material has been neutralized with a base, is also disclosed.
Claims17
A process for preparing secondary amines which comprises contacting an alcohol, aldehyde, or ketone with a primary amine in the presence of a catalyst under reaction conditions sufficient to form a secondary amine, wherein the catalyst comprises a homogeneous mixture of (a) 10-90 mole percent cobalt or an insoluble salt thereof, (b) 9-89 mole percent copper or an insoluble salt thereof, and (c) 1-20 mole percent of a metal or insoluble salt of a metal selected from the group consisting of a Lanthanum series metal, thorium, uranium, scandium, titanium, and yttrium.
A process for preparing secondary amines by contacting an alcohol, aldehyde or ketone with a primary amine in the presence of an effective amount of a catalyst under conditions effective to form a secondary amine, wherein the catalyst comprises a mixture of (a) 10-90 mole percent cobalt or an insoluble salt thereof, (b) 9-89 mole percent copper or an insoluble salt thereof, (c) 1-20 mole percent of a metal or insoluble salt of a metal selected from the group consisting of a Lanthanum series metal, zirconium, thorium, uranium, scandium, titanium, and yttrium;
- supported on a carrier material, wherein the carrier material has been neutralized with an alkali metal hydroxide.
