1648. JUNGERS, J. C., AND COUSSEMANT, F. [Effect of Adsorption on the Course of Catalytic Reaction.] Jour. Chim. Phys., vol. 47, 1950, pp. 139-144; Chem. Abs., vol. 44, 1950, p. 10,441.

Kinetics of gas-phase and liquid-phase catalytic reactions are interpreted in terms of the relative adsorptions of reactants and products. Reactions discussed include the hydrogenation of CO and CO₂ to CH₄ over Ni (abs. 2153, 2460), of C₆H₆ to cyclohexane in the presence of CO₂ (abs. 2461), of acetone to isopropyl alcohol; C₂H₂ to C₂H₄ (abs. 695), and the dehydrogenation of a secondary alcohol to a ketone (abs. 3398). The hydrogenation of PhOH to cyclohexanol takes place through the intermediate formation of cyclohexanone. A quantitative evaluation of the adsorption coefficients and the several reaction velocity constants is made. Similarly, the hydrogenation of naphthalene to decahydronaphthalene takes place through the formation of 1, 2, 3, 4-tetrahydronaphthalene. Intermediates in the hydrogenation of C₆H₆ to cyclohexane are not detected. The possible use of C₂H₂, CO₂, or other compounds as acceptors for H₂ in dehydrogenation catalysis is discussed.
