Ammoxidation of allyl alcohol – a sustainable route to acrylonitrile

The ammoxidation of allyl alcohol was demonstrated over antimony–iron oxide catalysts with a Sb/Fe ratio of 0.6 and 1. Both catalysts showed high performance with 83 and 84% yield of acrylonitrile, respectively, whereby the main difference was found in the initial performance. This was ascribed to the in-operando formation of the SbFeO4 mixed oxide on the catalyst surface under reaction conditions, as proven by XPS analysis.
