몰리브덴산 암모늄 C화학적 특성, 용도, 생산
화학적 성질
Ammonium molybdate is a colorless, white or slightly greenish-yellow powder. It is used in chemical analysis for the determination of phosphorus. From a nitric acid solution it precipitates phosphorus in the form of ammonium phosphomolybdate having the formula (NH4)3PO4-12MoO3 after drying at 110 °C(230°F). Some of the phosphomolybdic acids are used as reagents for the alkaloids and in the analysis and separation of the alkali metals.용도
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.생산 방법
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.정의
ChEBI: Ammonium molybdate is an ammonium salt composed of ammonium and molybdate ions in a 2:1 ratio. It has a role as a poison. It contains a molybdate.일반 설명
Ammonium molybdate can be prepared by dissolving molybdenum trioxide in ammonia.Safety Profile
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.잠재적 노출
It is used as an analytical reagent, in pigments and in the production of molybdenum metal and ceramics.운송 방법
There are no known UN/DOT restrictions.Purification Methods
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.]비 호환성
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.몰리브덴산 암모늄 준비 용품 및 원자재
