Abstract
Provided herein are catalysts useful in reductive amination, which include nickel, copper, zirconium and/or chromium, oxygen, and tin. The presence of the tin increases the selectivity of the catalyst in reductive aminations over the catalysts of the prior art.
Claims5
A catalyst useful in a reductive animation process for producing amines from alcohols, aldehydes, or ketones, wherein said catalyst consists of nickel, copper, tin, zirconium, and oxygen.
A catalyst useful in reductive amination consisting of:
- a) nickel, present in any amount between 40.0 and 90.0% by weight based upon the total catalyst weight;
- b) copper, present in any amount between 4.0 and 40.0% by weight based upon the total catalyst weight;
- c) tin, present in any amount between 0.20 and 20.0% by weight based upon the total catalyst weight;
- d) zirconium, present in any amount between 1.0 and 50.0% by weight based upon the total catalyst weight;
- and
- e) oxygen, present in any amount between 3.0 and 25.0% by weight based upon the total catalyst weight.

A catalyst useful in reductive amination consisting of:
- a) nickel, present in any amount between 60.0 and 80.0% by weight based upon the total catalyst weight;
- b) copper, present in any amount between 6.0 and 14.0% by weight based upon the total catalyst weight;
- c) tin, present in any amount between 1.0 and 7.0% by weight based upon the total catalyst weight;
- d) zirconium, present in any amount between 3.0 and 25.0% by weight based upon the total catalyst weight;
- and
- e) oxygen, present in any amount between 5.0 and 10.0% by weight wherein all percentages are based upon the total weight of the finished catalyst.
