Abstract
High Resolution Image Download MS PowerPoint Slide Direct ammoxidation of propane to acrylonitrile has been investigated recently as an alternate method for the current process based on propene. The Mo−V−Te−Nb−O mixed oxide is the most promising catalyst at present for this reaction. The reaction mechanism of propane ammoxidation over this catalyst is still not investigated experimentally. In this work, we have tested the presence of C6 intermediates during the course of the reaction using 13 C-labeled propane. The results show that a direct pathway for the ammoxidation of propane to acrylonitrile without skeletal rearrangement of the carbon backbone operates under realistic, steady-state conditions.
