Claims43
A method for producing amines comprising catalytically hydrogenating a nitrile or imine with a hydrogen-containing gas in the presence of a molded hydrogenation Raney catalyst, wherein the Raney catalyst is present in the form of hollow bodies.
The method for producing hexamethylenediamine (HMD) comprising catalytically hydrogenating adiponitrile with a hydrogen-containing gas in the presence of a molded Raney nickel hydrogenation catalyst in the form of hollow bodies.
A method for producing hexamethylenediamine (HMD) comprising catalytically hydrogenating adiponitrile with a hydrogen-containing gas and ammonia in the presence of a molded Raney nickel hydrogenation catalyst in the form of hollow bodies.
The method for producing hexamethylenediamine (HMD) comprising catalytically hydrogenating adiponitrile with hydrogen-containing gases in the presence of a molded Raney nickel hydrogenation catalyst in the form of hollow bodies and containing elements selected from groups 1A, 2A, 2B and/or 3A of the periodic system and/or germanium, tin, lead, antimony or bismuth.
A method for producing hexamethylenediamine (HMD) by catalytic hydrogenation of adiponitrile with hydrogen containing gases in the presences of a molded cobalt hydrogenation catalyst where the catalyst is present in the form of hollow bodies.
