Layered vanadyl alkylphosphates, where the alkyl groups are not only straig
ht-chain but also branched and cyclic ones, were prepared by reaction of a
mixture of V2O5 and V4O0 with P2O5 in alcohol. The distances between layers
of the vanadyl alkylphosphates increased linearly as the length of the alc
ohol increased. The (VO)(2)P2O7 catalyst obtained by calcination of vanadyl
methylphosphate exhibited a high performance in the oxidation of n-butane
to maleic anhydride.
