Transfer of Hydrogen by Hydroaromatics. 2. The Temperature Dependence of the Rate Constants and Catalytic Site Populations in the Tetralin/Iron Catalyst Systems

Article abstract of DOI:10.1021/j150605a024

The heterogeneous mechanism of dehydrogenation for the tetralin/iron catalyst system previously reported is further documented.The temperature dependences of the rate constants are reported.The effective activation energies on these heterogeneous surface were found to be in the -20 to +30 kcal/mol range.The catalytic site populations and temperature dependences were used to determine the binding energy, R_b, of the organic reactants at the catalytic sites.The E_b values were found to be in the 20-40 kcal/mol range.
