Abstract:
A method is proposed for the synthesis of heteropoly acids from oxides of molybdenum, tungsten, and vanadium via mechanochemical activation. The fundamental principles of this approach to the synthesis of heteropoly acids containing different ligands and heteroatoms are formulated. The new V2O5· nMoO3 compounds synthesized in this work are found to be highly reactive with phosphoric acid, which is due to the unsaturated coordination of the vanadium cations and the low structural perfection of these compounds. The application area of the proposed method is established. It appears to be most effective in the synthesis of phosphomolybdovanadic and phosphomolybdic heteropoly acids. In some instances, heteropoly acids can be prepared by solid-state reactions, which makes it possible to use V2O5· nMoO3 compounds with n ≤ 6 as starting reagents. The method has a number of important advantages: the process is waste-free, requires a shorter synthesis time and involves a smaller number of steps as compared to the existing processes, affords an increased yield of heteropoly acids, and involves no explosion- or fire-hazardous steps.
