METHOD FOR HYDROGENATING AN AROMATIC CHARGE USING AS A CATALYST A SUSPENSION OF METAL NANOPARTICLES CONTAINING A NITROGEN LIGAND IN AN IONIC LIQUID

摘要

The invention relates to a method for hydrogenating an aromatic charge using as a catalytic composition a suspension of metal nanoparticles having an average size of between 1 and 20 nm in at least one non-aqueous ionic liquid, said suspension also including a nitrogen ligand, wherein said metal nanoparticles include a transition metal at a zero valence state, the transition metal being selected from the Groups 8, 9, 10 and 11 of the periodic table and said nitrogen ligand including from 1 to n nitrogen atoms, n being an integer between 1 and 20.
