Abstract
The invention relates to a passivated hydrogenation catalyst that is embedded in a primary amine, a derivative thereof, and/or a nitrile, the process to make such catalysts, as well as the use of such catalysts in a hydrogenation process in which an amine or a derivative thereof is produced.
Claims20
A pasaivated hydrogenation catalyst that is embedded in at least one embedding agent selected from the group consisting of:
- primary amines, represented by the formula R—CH2—NH2 (I), wherein R is selected from the group consisting of linear or branched, substituted or unsubstituted, saturated or unsaturated, optionally O-containing and optionally N-moieties containing 7 to 30 carbon atoms,
- derivatives of said primary amines, represented by the formula R—CH2—NR′R″ (II), wherein R is as defined above and R′ and R″ are independently selected from hydrogen and the group consisting of linear or branched, substituted or unsubstituted, saturated or unsaturated, optionally O-containing and optionally N-containing moieties containing 3 to 30 carbon atoms, with the proviso that at most one of R′ and R″ is hydrogen,
- nitriles, represented by the formula R—C≡N (III), wherein R is selected from the group consisting of linear or branched, substituted or unsubstituted, saturated or unsaturated, optionally O-containing and optionally N-containing moieties containing 7 to 30 carbon atoms,
- ether amines,
- ether diamines, and
- mixtures of any of said primary amines, derivatives thereof, nitrites, ether amines, and ether diamines.
