Descripción: Phospho-tungstic and phospho-molybdic Wells-Dawson heteropolyacids, H₆P₂W₁₈O₆₂.xH₂O and H₆P₂Mo₁₈O₆₂.xH₂O respectively, were synthesized through ion exchange with a higher yield (∼ 90%) than the conventional organic route (∼ 70%). Pure, non-degraded heteropolyacids are obtained when the corresponding ammonium salt [(NH₄)₆P₂W₁₈O₆₂.13H₂O or (NH₄)₆P₂Mo₁₈O₆₂.12H₂O] is kept in contact with an acid resin [about (1:0.8) salt:resin weight ratio] up to three days. The use of an organic media instead of an aqueous media greatly favors the completeness of the exchange.
