Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>The effect of water on the selective gas phase oxidation of acrolein to acrylic acid on a Mo/V/W mixed oxide catalyst was studied by performing steady‐state isotopic transient kinetic analysis experiments with H₂¹⁸O. Experiments were performed in the temperature range of 90–345 °C at ambient pressure. It could be shown that acrolein exchanges its carbonylic oxygen with oxygen from water even at low temperatures (&lt;200 °C), at which no acrolein oxidation occurs. At higher temperatures (&gt;200 °C), the oxygen atoms of the water molecules incorporate into all oxidation products such as acrylic acid, carbon monoxide, and carbon dioxide.</p> </abstract>
