Abstract
Kinetics of p-xylene oxidation in an aqueous system catalyzed by cobalt oxide have been studied at 140 °C under oxygen. The reaction is second order in p-xylene and first order in cobalt oxide concentration. The rate constant and product distribution are very close to those found for homogeneous catalytic reactions. Based on these findings, a reaction scheme describing the influence of oxide catalyst is formulated.
Abstract
Исследована кинетика окисления п-ксилола в водных средах, катализированная окисыо кобалята, при 140° C и в атмосфере кислорода. Скоростя реакции имеет второй порядок по концентнации п-ксилола и первый порядок по концентрации окиси кобальта. Величина константы скороти и распределение продуктов реакции очень подобны величинам, полученным вгомогенной катализировннаь реакции. На этоь основе составлена реакционная схема, формулирующая влияние окисного каталиэатора.
