General Description
A lemon yellow liquid. Boiling point 257-260°F (125-127°C). Corrosive to metals and tissue. Used as a catalyst.
Hazards
Reactivity Alerts
- Water-Reactive
- Air-Reactive
Air & Water Reactions
Fumes in air. Reacts with moist air to form vanadic acid and hydrochloric acid fumes [Von Schwartz 1918. p.321]. Reacts exothermically with water to generate acidic fumes and acidic solutions. Violently hygroscopic.
Fire Hazard
Special Hazards of Combustion Products: Irritating fumes of hydrogen chloride may form in fires. (USCG, 1999)
Health Hazard
Inhalation of vapor causes irritation of nose and throat. Ingestion causes irritation of mouth and stomach. Contact with eyes or skin causes severe irritation. (USCG, 1999)
Reactivity Profile
VANADIUM OXYTRICHLORIDE is incompatible with bases, including amines, with strong oxidizing agents, and with alcohols. May react vigorously or explosively if mixed with diisopropyl ether or other ethers in the presence of trace amounts of metal salts [J. Haz. Mat., 1981, 4, 291]. Combination with sodium metal led to a violent explosion [Bretherick 5th ed., 1995].
Belongs to the Following Reactive Group(s)

Response Recommendations
Isolation and Evacuation
Excerpt from 137
[Substances - Water-Reactive - Corrosive]:
IMMEDIATE PRECAUTIONARY MEASURE: Isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids.
SPILL: Increase the immediate precautionary measure distance, in the downwind direction, as necessary.
FIRE: If tank, rail car or tank truck is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2020)
Firefighting
Excerpt from 137
[Substances - Water-Reactive - Corrosive]:
When material is not involved in fire, do not use water on material itself.
SMALL FIRE: Dry chemical or CO2. If it can be done safely, move undamaged containers away from the area around the fire.
LARGE FIRE: Flood fire area with large quantities of water, while knocking down vapors with water fog. If insufficient water supply, responders should withdraw.
FIRE INVOLVING TANKS OR CAR/TRAILER LOADS: Cool containers with flooding quantities of water until well after fire is out. Do not get water inside containers. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks engulfed in fire. (ERG, 2020)
Non-Fire Response
Excerpt from 137
[Substances - Water-Reactive - Corrosive]:
Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Stop leak if you can do it without risk. Use water spray to reduce vapors; do not put water directly on leak, spill area or inside container. Keep combustibles (wood, paper, oil, etc.) away from spilled material.
SMALL SPILL: Cover with DRY earth, DRY sand or other non-combustible material followed with plastic sheet to minimize spreading or contact with rain. Use clean, non-sparking tools to collect material and place it into loosely covered plastic containers for later disposal. Prevent entry into waterways, sewers, basements or confined areas. (ERG, 2020)
