[origin: WO2012018310A1] Title: Process for the production of highly pure dicyclohexylamine from by- products resulting from the production of cyclohexylamine Process for the production of highly pure dicyclohexylamine during the production of cyclohexylaminefrom aniline in a liquid phase on ruthenium catalyst on thealuminium carrier or coalconsists in that the concentrated dicyclohexylamine obtained by amultiple rectification of the reaction mixture is again catalytically hydrogenated on the metal Ru,Pd,Ptor Rhcatalyston the carrier, at the temperature between 80 and 240°Cand pressure between 0.1 and 9.0 MPa,in the same or in other hydrogenation device, whereby above 99.0% w/wconcentrated dicyclohexylamine is obtained.
