Some aspects of the reaction mechanism of n-butane and n-pentane selective oxidn. on vanadyl pyrophosphate obtained in transient response studies using the TAP (Temporal Anal. of Products) reactor system are presented. Key features include the evolution of the surface properties of the catalyst during alkane oxidn., the role of org. adspecies and different types of reactive oxygen in the reaction mechanism and their influence on the surface microkinetics, the relationship between surface lifetime of adsorbed species and selectivity, and the role of org. precursors in phthalic anhydride formation from n-pentane.

Abstract
Some aspects of the reaction mechanism of n-butane and n-pentane selective oxidn. on vanadyl pyrophosphate obtained in transient response studies using the TAP (Temporal Anal. of Products) reactor system are presented. Key features include the evolution of the surface properties of the catalyst during alkane oxidn., the role of org. adspecies and different types of reactive oxygen in the reaction mechanism and their influence on the surface microkinetics, the relationship between surface lifetime of adsorbed species and selectivity, and the role of org. precursors in phthalic anhydride formation from n-pentane.
