Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>Oxidation of acrolein to acrylic acid on Mo/V/W‐mixed oxide catalysts has been studied by means of the isotopic exchange method steady‐state isotopic transient kinetic analysis (SSITKA). As a result of these isotopic exchanges performed with ¹⁶O₂ and ¹⁸O₂, some new mechanistic details could be obtained. Acrolein exchanges its oxygen with oxygen of the mixed oxide catalyst. Additionally, the kinetics of the different isotopologues is significantly influenced by oxygen exchange reactions between the surface and the bulk sites. From the SSITKA results, an extended reaction model has been deduced. Thus, the experimentally gained data of the individual isotopologue kinetics could be verified by modeling.</p> </abstract>
