Abstract
An adsorption-calorimetric study was performed to determine the thermodynamic characteristics of adsorption of acetone on Raney nickel from aqueous solutions of 2-propanol of various compositions directly during liquid-phase hydrogenation. At adsorbate concentrations below 3 × 10−3 M, adsorption occurred by the mechanism of the filling of the pore volume of the catalyst with saturated solutions of complex compositions. At higher concentrations, the process followed the mechanism of condensation interactions. Two-dimensional phase diagrams were obtained for Raney nickel surface layers involved in the adsorption of acetone. These diagrams substantiated the possibility of two-dimensional phase transitions in adsorption solutions.
