Abstract
Tertiary amines are produced by reacting aliphatic, cycloaliphatic or araliphatic alcohols, aldehydes or ketones with ammonia, primary or secondary amines in the presence of a catalyst having improved selectivity and stability and which comprises a mixture of copper, tin and an alkali metal supported on a suitable carrier.
Claims18
A catalyst for the production of tertiary amines by reacting aliphatic, cycloaliphatic or araliphatic alcohols, aldehydes or ketones having up to twenty-five carbon atoms with ammonia, primary or secondary amines having from one to eight carbon atoms wherein the alkyl moiety of the alcohol, aldehyde or ketone replaces the hydrogen(s) on the ammonia, primary or secondary amines which comprises from about 0.05 to about 50 percent by weight of copper, from about 0.05 to about 50 percent by weight of tin and from about 0.003 to about 30 percent by weight of an alkaline metal supported on a porous carrier.
In the process for preparing tertiary amines by reacting aliphatic, cycloaliphatic or araliphatic alcohols, aldehydes or ketones having up to twenty-five carbon atoms with ammonia, primary or secondary amines having from one to eight carbon atoms in a reducing atmosphere at a temperature of from about 160.degree. C. to about 350.degree. C. wherein the alkyl moiety of the alcohol, aldehyde or ketone replaces the hydrogen(s) on the ammonia primary or secondary amine, the improvement which comprises carrying of the reaction in the presence of a catalyst comprising from about 0.05 to about 50 percent by weight of copper, from about 0.05 to about 50 percent by weight of tin and from about 0.003 to about 30 percent by weight of an alkali metal supported on a porous carrier.
