Abstract
Two classes of reactions have been examd., in order to analyze the factors that are fundamental in detg. the selectivity. The first one is the C4 conversion to maleic anhydride. The reactivity of n-butane, 1-butene and butadiene over (VO)2P2O7 catalyst was compared, and the key properties of the catalyst were examd. The second example deals with the ammoxidn. of alkylaroms. over V2O5/TiO2 catalysts. In both cases, the control of the vanadium valence state was a key parameter in detg. the catalyst activity and selectivity. [on SciFinder(R)]File in questo prodotto:
