Vanadyl sulfate Usage And Synthesis

Uses

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.

Preparation

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

Chemical Properties

Vanadyl sulfate is a pale blue crystalline powder. Odorless.

Physical properties

The dihydrate, VOSO4?2H2O is a blue black crystalline powder, soluble in water.

General Description

A blue crystalline solid. Very soluble in water. Denser than water. Contact may irritate skin, eyes, and mucous membranes. May be toxic by ingestion, inhalation and skin absorption.

Reactivity Profile

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.

Fire Hazard

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.

Safety Profile

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.

Potential Exposure

Vanadyl sulfate is used as a fixative for textile dyes, a colorant for glass and ceramics; a reducing agent and a catalyst.

Veterinary Drugs and Treatments

Shipping

UN2931 Vanadyl sulfate, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.

Incompatibilities

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.
