AbstractThe catalytic activity of supported V2O5‐alkalimetal sulfate catalysts was studied by oxidizing toluene and methanol to aldehydes and water. An isothermal, fixed‐bed reactor, operating at atmospheric pressure and temperatures of 320, 345, and 370°C, was used to obtain the reaction rate data for different partial pressure combinations of the reaction components of these two systems. Three different approaches, Langmuir‐Hinshelwood, Hinshelwood, and two‐step redox mechanisms, have been used to study the kinetics, with statistical data interp
