Molybdenum trioxide CAS 1313-27-5 MoO3

Molybdenum trioxide (MoO3), also known as molybdenum anhydride, molecular weight 143.94, white transparent rhombohedral crystals, slightly greenish color, turning yellow when heated, and returning to its original color after cooling. Density 4.692g/cm3, melting point 795℃, boiling point 1155℃, easy to sublimate. Insoluble in water, can be melted in ammonia and strong alkali solution, generate molybdate. Dissolved in strong acid, generating molybdenum dioxide (MoO22+) and molybdenum oxide (MoO4+) complex cation, and the acid root can form soluble complexes. The oxidizing property is very weak, and it can be reduced by hydrogen, carbon and aluminum at high temperature. Reacts with phosphoric acid to form phosphomolybdic acid.

1. Performance and use:

Molybdenum(VI) oxide is used in catalyst compositions to carry out desulfurization of petroleum feedstocks and to remove nitrogen-containing compounds from petroleum fractions. Other uses of this oxide include preparation of various molybdate salts and as reagents for chemical analyses.

Chiefly as a reagent for chemical analysis.Used for trace metal analysis.

Molybdenum trioxide (MnO3) is a compound used to make enamels adhere to metals.

3. Packaging and storage

Molybdenum trioxide solid is packaged in plastic woven bags lined with polyethylene bags, with a net weight of 25kg per bag, which can also be determined according to user needs.

Store in a cool and ventilated place indoors, avoid moisture and exposure, and the storage period is twelve months.

4. Safety protection

Poison by ingestion, subcutaneous, and intraperitoneal routes. Human systemic effects by inhalation: pulmonary fibrosis and cough. Questionable carcinogen with experimental neoplastigenic data. A powerful irritant. Explodes on contact with molten magnesium. Violent reaction with interhalogens (e.g., bromine pentafluoride, chlorine trifluoride). Incandescent reaction with hot sodium, potassium, or lithium. When heated to decomposition it emits toxic fumes of Mo.
