27774-13-6(Hazardous Substances Data) |
| Hazard Information | Back Directory | [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(27774-13-6) has weak oxidizing or reducing powers. Redox reactions can however still occur. | [Air & Water Reactions]
Very soluble in water. | [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. | [Potential Exposure]
Vanadyl sulfate is used as a fixative
for textile dyes, a colorant for glass and ceramics; a reducing
agent and a catalyst. | [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. | [First aid]
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts the
skin, remove contaminated clothing and wash immediately
with soap and water. Seek medical attention immediately.
If this chemical has been inhaled, remove from exposure,
begin rescue breathing (using universal precautions, including
resuscitation mask) if breathing has stopped and CPR if
heart action has stopped. Transfer promptly to a medical
facility. When this chemical has been swallowed, get medical
attention. Give large quantities of water and induce
vomiting. Do not make an unconscious person vomit.
Medical observation is recommended for 24 to 48 hours
after breathing overexposure, as pulmonary edema may be
delayed. As first aid for pulmonary edema, a doctor or
authorized paramedic may consider administering a drug or
other inhalation therapy. | [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. | [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. | [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. | [Definition]
ChEBI: Vanadyl sulfate is a vanadium coordination entity and a metal sulfate. | [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 | [Flammability and Explosibility]
Nonflammable | [Side effects]
Commonly reported side effects of vanadyl sulfate include gastrointestinal issues such as nausea, diarrhea, and stomach cramps. These mild side effects tend to subside with continued use or dose adjustment. However, they can be bothersome and might deter some individuals from using the supplement. More serious risks, though rare, include toxicity from excessive intake. High doses of vanadium compounds can lead to issues such as liver and kidney damage. Therefore, it’s essential to adhere to recommended dosages and avoid excessive use.
| [Synthesis]
High-purity vanadyl sulfate (VOSO4) electrolyte is a key precursor for vanadium redox flow batteries. Jing Wang and colleagues develop a short-process route to directly prepare high-purity VOSO4 electrolyte from the sulfuric acid leachate of calcification-roasted vanadium slag through reduction pretreatment, solvent extraction, scrubbing, and stripping. Di-(2-ethylhexyl) phosphoric acid (P204) was used as the extractant[1]. | [Veterinary Drugs and Treatments]
