PALLADIUM-CONTAINING HYDROGENATION CATALYST AND METHOD FOR PRODUCING IT Russian patent published in 2015 - IPC B01J23/44 B82B3/00 B01J27/24 B01J37/02 

FIELD: chemistry.

SUBSTANCE: problem is solved by using graphite oxide functionalised by ethylene amide as a carrier. The described method for preparing a palladium-containing hydrogenation catalyst by coating a carbon nanomaterial with a bivalent palladium salt (PdCl₂) followed by reducing to zero-valent palladium by sodium borane in the hydrogen medium, differs by the fact that the used carbon nanomaterial is graphite oxide modified by ethylene amide and prepared by boiling a graphite oxide suspension in butanol-1 in the presence of excessive ethylene amine. The palladium content in the catalyst makes 4.8-5 wt %. The catalyst is stable in the standard environment and keeps being active at long air storage, as well as maintains its activity after repeated hydrogenation cycles involving no regeneration.

EFFECT: creating the palladium-containing hydrogenation catalyst, wherein the palladium particles have a nanometre size and are uniformly distributed over the carrier surface.
