Abstract
The invention relates to a ruthenium promoted nickel and/or cobalt dehydrogenation-hydrogenation catalyst. The ruthenium on the catalyst is applied from a solution containing a ruthenium halide compound. The catalyst use in organic reactions and a process performed in its presence are also described. Preferably, the catalyst is used to aminate alkylene oxides, alcohols, phenols, alkanolamines, aldehydes, and ketones.
Claims22
A process of catalyzing an amination reaction in which one of an alkylene oxide, a hydroxyl-containing compound, an aldehyde, and a ketone is reacted with one of ammonia, a primary amine, and a secondary amine, and which favors the formation of primary or noncyclic amines, comprising conducting the reaction in the presence of a halogen-containing, ruthenium-promoted, nickel and/or cobalt catalyst containing:
- from 4 to 40 % by weight, based on the total weight of said catalyst, of at least one metal selected from nickel and cobalt;
- from 0.1 to 5 % by weight, based on the total weight of said catalyst, of ruthenium which ruthenium was introduced as a solution of ruthenium halide;
- and
- a porous metal oxide support comprised of at least 50 % by weight of activated alumina,
- wherein said at least one metal selected from nickel and cobalt and said ruthenium are in the metallic state.
A process for the manufacture of amination products which favors the formation of primary or noncyclic amines by reacting one of an alkylene oxide, a hydroxyl-containing compound, an aldehyde, and a ketone with one of ammonia, a primary amine, and a secondary amine at a temperature ranging from 120.degree. to 300 .degree. C. in the presence of hydrogen gas and a halogen-containing, ruthenium-promoted, nickel and/or cobalt catalyst containing:
- from 4 to 40% by weight, based on the total weight of said catalyst, of at least one metal selected from nickel and cobalt;
- from 0.1 to 5% by weight, based on the total weight of said catalyst, of ruthenium, which ruthenium was introduced as a solution of ruthenium halide;
- and
- a porous metal oxide support comprised of at least 50% by weight of activated alumina,
- wherein said at least one metal selected from nickel and cobalt and said ruthenium are in the metallic state.
The process according to claim18, wherein the catalyst contains from 5 to 20% by weight of the at least one metal selected from nickel and cobalt, from 0.2 to 3% by weight of the ruthenium, and the porous metal oxide support is comprised of at least 98% by weight of activated alumina.
