Heteropoly Acids
Mo or W-based heteropoly acids, known for strong acidity and redox activity, serve as efficient and eco-friendly catalysts for a variety of organic reactions.
Features
Emerging Heteropoly Acids
Polyacids are polynuclear inorganic acids formed by transition metals such as molybdenum (Mo) and tungsten (W) coordinated with oxygen (O). When phosphorus (P), silicon (Si), or other heteroatoms are incorporated, they become heteropoly acids (HPAs) such as phosphotungstic acid, silicotungstic acid, and phosphomolybdic acid.
Industrial Uses and Large-Scale Production Technology
HPAs exhibit exceptional acidity, high water solubility, thermal stability, and redox properties, making them key catalysts in various industrial organic reactions. Their ease of recovery and reuse in heterogeneous systems and low environmental impact have driven growth in organic synthesis and petrochemistry.
Phosphotungstic and silicotungstic acids excel in esterification and dehydration reactions—thanks to acidity exceeding that of sulfuric acid—while phosphomolybdic acid is prized for powerful oxidative applications. Given their environmentally friendly profile and catalytic versatility, HPAs are set to play an ever greater role across industries. As the world’s first to establish large-scale HPA production, we are committed to supporting a sustainable society through reliable supply of high-quality heteropoly acids.
