Abstract
A vibrational study of acetonitrile adsorbed on Raney nickel has been performed using inelastic neutron scattering. The chemisorption is associative and no C-H bond breaking is observed up to 393 K. Acetonitrile is found to be adsorbed parallel to the surface. The vibrational modes of the molecule are not very perturbed, this indicates a weak interaction with the surface. The coverage of the metal surface by acetonitrile is small, which has also been observed in the hydrogenation reaction in the gas phase. The excellent selectivity for the primary amine formation can be explained by this weak chemisorption.
