Abstract
The surface transformations of propylene, allyl alc., and acrylic acid (acrylonitrile formation intermediates) in the presence or absence of NH3 over V antimonate catalyst were studied by IR spectroscopy. The results show the existence of various possible pathways of surface transformation in the mechanism of propane ammoxidn., depending on the reaction conditions and the surface coverage with chemisorbed NH3. A surface reaction network is proposed and used to explain the catalytic behavior obsd. under flow reactor conditions. [on SciFinder(R)]File in questo prodotto:
