New layered vandyl(IV) phosphite as a precursor to vanadyl pyrophosphate catalysts for partial oxidation of n-Butane to maleic anhydride
- Princeton Univ., NJ (United States)
The synthesis and characterization of layered vanadyl(IV) phosphonates, VOC{sub n}H{sub 2n+1}PO{sub 3}{center_dot}xH{sub 2}O containing the V{sub 2}O{sub 8} dimers have been recently reported. The authors present here the results of partial oxidation of n-butane on VPO catalysts derived from the simplest of these phosphonates, vanadyl phosphite. The results indicate that vanadyl(IV) phosphite is the precursor to vanadyl pyrophosphate catalysts with high surface area (ca. 45 m{sup 2}/g) and selectivity to maleic anhydride in n-butane partial oxidation comparable to the conventional unpromoted catalyst. 10 refs., 3 figs., 1 tab.
