Abstract:
A new ecofriendly process is proposed for the synthesis of aqueous solutions of Mo-V-phosphoric Keggin heteropoly acids H3 + x PV x Mo12 − x O40(HPA−x ). First, V2O5 is dissolved in cooled H2O2 to form peroxyvanadium compounds, which then spontaneously decompose to yield the H6V10O28 solution. The latter is stabilized by the addition of H3PO4 to yield an H9PV14O42 solution. This solution is gradually added to a boiling H3PO4 + MoO3 aqueous suspension. This suspension is gradually evaporated that is followed by dissolution of MoO3 to produce an HPA−x solution. This process is reliable and almost non-waste and is promising for preparing HPA−x solutions with x = 2–6 on pilot and large scales.
