The production of acrylonitrile from biomass is in its infancy. We have reviewed the most pertinent literature in this area and find that the highest yields of acrylonitrile (60 %, on 5 cc microreactor scale) are obtained from glycerol as the biomass

Site isolation and phase cooperation are two important concepts in selective oxidation catalysis and are useful in the design and discovery of new catalysts. Site isolation deals with the limitation of active oxygens at the catalytic site with the ai

In an earlier publication (Grasselli et al., Top Catal 54:595, 2011) [1] we analyzed the distribution of key catalytic elements at the active site of the M1 phase of the MoVNbTeOx catalyst system based on the definition of this center put forth in ou

Key patents for the oxidation of n-butane to maleic anhydride (MA) using V/P mixed metal oxides (VPO) have been analyzed to evidence the important parameters needed to optimize the catalytic behaviour. The important aspects for the optimization of th

The M1 phase of the MoV(Nb,Ta)TeO system is one of the most effective catalysts for the ammoxidation and selective oxidation of propane to acrylonitrile (AN) and acrylic acid, respectively. The active centers of the M1 phase reside on the ab planes o

Selective doping of (M1) Mo7.8V1.2NbTe0.94O28.9 and (M2) Mo4.67V1.33Te1.82O19.82 phases with P significantly enhance acrylic acid yields (2-15%) in propane/propylene oxidation. Amorphous overlayers (Te-molybdate) seriously inhibit acrylic acid format
