An adsorption calorimetry study of the adsorption of acetone on raney nickel under conditions of liquid-phase hydrogenation

Adsorption calorimetry was used to study the characteristics of the adsorption of acetone on Raney nickel from 2-propanol-water solutions under conditions of liquid-phase hydrogenation. The isotherms of adsorption of acetone on Raney nickel and the dependences of integral and differential heats of adsorption on the adsorption value were obtained. It was established that the adsorption of acetone on Raney nickel occurs by the mechanism of volume filling of micropores in the pore space of the catalyst with adsorbate solution, which consists of partially or completely desolvated acetone molecules irrespective of the concentration of 2-propanol in the solvent.
