Patent ID: 7208448

Claim:
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—CH 2 —NH 2 (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—CH 2 —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.
