Chemische Eigenschaften

Ammonium molybdate is a colorless, white or slightly greenish-yellow powder.

Verwenden

Ammonium molybdate has been used to prepare phosphomolybdates. (NH4)2MoO4 was used as an analytical reagent for quantitative analysis of phosphates, silicates, arsenates and lead in their aqueous solutions. At saturated concentration, (NH4)2MoO4 was used to perform cryo-negative staining and as a negative stain in biological electron microscopy. Ammonium molybdate was used in study of crystallisation of cell-free-expressed membrane proteins.

Vorbereitung Methode

Pure molybdic oxide (99.95% MoO3) is prepared by sublimation of technical oxide or by calcining ammonium molybdate. Metallic molybdenum powder is prepared commercially by hydrogen reduction of either pure molybdic oxide or ammonium molybdate in a two-step process.

Definition

ChEBI: An ammonium salt composed of ammonium and molybdate ions in a 2:1 ratio.

Allgemeine Beschreibung

Ammonium molybdate can be prepared by dissolving molybdenum trioxide in ammonia.

Sicherheitsprofil

Poison by ingestion and intraperitoneal routes. Moderately toxic by other routes. An irritant. See also MOLYBDENUM COMPOUNDS. When heated to decomposition it emits toxic fumes of NH3 and NOx.

mögliche Exposition

It is used as an analytical reagent, in pigments and in the production of molybdenum metal and ceramics.

Versand/Shipping

There are no known UN/DOT restrictions.

läuterung methode

Crystallise the salt from water (2.5mL/g) by partial evaporation in a desiccator. [Sturdivant J Am Chem Soc 59 630 1937, Grüttner & Jauder in Handbook of Preparative Inorganic Chem (Ed. Brauer) Academic Press Vol II p 1711 1965.]

Inkompatibilitäten

Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides; chemically active metals (such as potassium, sodium, magnesium and zinc) may cause a violent reaction.
