Chemische Eigenschaften
Vanadyl sulfate is a pale blue crystalline powder. It is odorless and very soluble in water. It is denser than water. Contact may irritate skin, eyes, and mucous membranes. It may be toxic if ingested, inhaled, or absorbed through the skin.
Physikalische Eigenschaften
The dihydrate, VOSO₄.2H₂O is a blue black crystalline powder, soluble in water.
Verwenden
The dihydrate is a mordant in dyeing and printing fabrics; used in preparing aniline black; a colorant in ceramics to form blue and green glazes; used in making colored glass; and a reducing agent.
Definition
ChEBI: Vanadyl sulfate is a vanadium coordination entity and a metal sulfate.
synthetische
Vanadyl sulfate is prepared by passing sulfur dioxide through a cold solution of vanadium pentoxide in sulfuric acid, followed by crystallization:
V2O5 + H2SO4 + H2O + SO2 → 2VOSO4 + 2H2O
Allgemeine Beschreibung
Vanadyl sulfate is a sulfate of vanadium that occurs naturally as the mineral pauflerite. It is a common source of vanadium in the laboratory. Vanadyl sulfate is an intermediate in the extraction of vanadium from petroleum residues and is also a component of some food supplements and drugs. Vanadium is a transition metal with the chemical symbol V and atomic number 23. The element usually combines with other elements such as oxygen, sodium, sulfur, or chloride, and occurs naturally in about 65 different minerals and in fossil fuel deposits. Vanadium is found in many organisms, and is used by some life forms as an active center of enzymes. (L837, L838, L852)
Reaktivität anzeigen
Vanadyl sulfate has weak oxidizing or reducing powers. Redox reactions can however still occur.
Health Hazard
Highly toxic, may be fatal if inhaled, swallowed or absorbed through skin. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
Brandgefahr
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Containers may explode when heated. Runoff may pollute waterways.
Flammability and Explosibility
Non flammable
Sicherheitsprofil
A poison and an inhalation hazard. Poison by intravenous, intraperitoneal, and subcutaneous routes. Mutation data reported. When heated to decomposition it emits toxic fumes of VOx and SOx. See also SULFATES and VANADIUM COMPOUNDS.
mögliche Exposition
Vanadyl sulfate is used as a fixative for textile dyes, a colorant for glass and ceramics; a reducing agent and a catalyst.
Versand/Shipping
UN2931 Vanadyl sulfate, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.
Inkompatibilitäten
Vanadyl sulfate has weak oxidizing or reducing powers. Redox reactions can however still occur. 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. Vanadyl sulfate may attack metals; sulfates react with aluminum, magnesium.
