Abstract The highly selective hydrogenation of adiponitrile proceeds effectively in supercritical carbon dioxide (scCO 2) to produce 6-aminocapronitrile with excellent selectivity of 100% over rhodium/alumina (Rh/Al 2 O 3) and without any additive, which is impossible in classical organic solvents. The presence of CO 2 can be beneficial or mandatory for the exclusive formation of the aminonitrile as it can act as a solvent to ...
