Abstract
The contribution of thermal methods of anal. to the study of the structure and reactivity of V-P oxides is examd. In particular, data are reported on the solid-state reaction VOHPO4.1/2H2O → (VO)2P2O7 + 2 H2O for VOHPO4.1/2H2O prepd. in different ways, on the redox properties of oxidn. and redn. of V for catalysts prepd. with different P:V at. ratios in the range 0.9-1.3, and on the surface properties detd. by TPD of catalysts with different P:V ratios. The relationship between these properties and the catalytic properties in the selective oxidn. of butane and but-1-ene is discussed. [on SciFinder(R)]File in questo prodotto:
