Abstract
Adsorption of hydrogen, p-nitrotoluene, p-toluidine and water on Raney nickel from their methanol solutions has been investigated under catalytic conditions. The isotherms of reversible adsorption of hydrogen are linear and the estimated heat of adsorption is 28.9 kJ mol-1. The amount of hydrogen held irreversibly on the catalyst is very large as compared to that adsorbed reversibly. The isotherms of adsorption of p-nitrotoluene, p-toluidine and water have different shapes (viz. types H3, S1 and L3 respectively). Among the reaction species, p-toluidine is not adsorbed on the catalyst at low concentrations (< 0.8 mmol cm-3).
