Collection: Tungsten [Catalysis and Inorganic Chemistry]
Tungsten [Catalysis and Inorganic Chemistry] — collects tungsten compounds in various forms, from tungsten oxides and chlorides, heteropoly acids such as phosphotungstic acid and hydrated tungstosilicic acid, to functional polymers based on phosphotungstate. This class represents the transition element tungsten with diverse oxidation states and coordination structures.
Tungsten and its compounds are used as catalysts or precatalysts in oxidation, metathesis, and epoxidation reactions, as well as reagents in polyoxometalate chemistry for inorganic catalysis research. Catalysis and inorganic chemists use tungsten heteropoly acids as Brønsted or Lewis acid catalysts in various organic transformations.
Example products in this collection: TCI T4005 12036-22-5 Tungsten(IV) Oxide, TCI I1204 12027-43-9 Tungstosilicic Acid Hydrate, TCI T2566 13283-01-7 Tungsten(VI) Chloride, TCI P1697 Poly[[N-isopropylacrylamide-co-[N-[3-(dodecyldimethylammonio)propyl]acrylamide]]phosphotungstate], TCI P3008 12501-23-4 Phosphotungstic Acid Hydrate.
Pay attention to the hydration status of tungsten heteropoly acids (phosphotungstate, tungstosilicate) and the oxidation state of tungsten in halide or oxide compounds, as both affect catalytic reactivity. All products are original products of Tokyo Chemical Industry (TCI) Japan, with purity, packaging, and storage conditions listed on each item's page.
