Kinetics of oxidation of pseudocumene in the vapor phase

Abstract

The kinetics of pseudocumene oxidation in the vapor phase with tin vanadate as catalyst have been studied over the following ranges of the variables: Oxygen concentration, 0.909 to 2.857 mole/m3; pseudocumene concentration, 0.071 to 0.125 mole/m3; temperature, 260 to 320°C; space time, 22.5 to 90 × 104 g. catalyst/mole sec. Oxidation‐reduction models have been found to describe the kinetics adequately. The mechanism is found to remain the same throughout the temperature range covered.
