ABSTRACT:
The yield of alkyl vanadate formed by the reaction of vanadium pentoxide and an alkyl alcohol in the presence of an azeotroping agent and, preferably, a catalyst is improved by the present invention. It involves lowering, prior to the reaction, the amount of vanadium having a valence lower than +5 in the vanadium pentoxide reagent.
