| | VANADIUM (IV) CHLORIDE Usage And Synthesis |
| Chemical Properties | Red liquid. Decomposes slowly to vanadium trichloride
and chlorine below63C. Soluble in absolute alcohol
and ether. Nonflammable. | | Chemical Properties | Vanadium tetrachloride is a thick, reddishbrown
liquid that gives off fumes on exposure to moist air. | | Uses | Preparation of vanadium trichloride, vanadium
dichloride, and organovanadium compounds. | | Air & Water Reactions | Forms acid mists in moist air. Reacts with water to form corrosive fumes of HCl. Handling Chemicals Safely 1980. p. 952). | | Reactivity Profile | VANADIUM (IV) CHLORIDE decomposes by the action of light with the formation of Cl2 gas. Reacts as an acid to neutralize bases. These neutralizations generate heat. Usually does not react as either oxidizing agents or reducing agents but such behavior is not impossible. May catalyze organic reactions. | | Health Hazard | CORROSIVE and/or TOXIC; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death. Fire will produce irritating, corrosive and/or toxic gases. Reaction with water may generate much heat that will increase the concentration of fumes in the air. Contact with molten substance may cause severe burns to skin and eyes. Runoff from fire control or dilution water may cause pollution. | | Fire Hazard | EXCEPT FOR ACETIC ANHYDRIDE (UN1715), THAT IS FLAMMABLE, some of these materials may burn, but none ignite readily. May ignite combustibles (wood, paper, oil, clothing, etc.). Substance will react with water (some violently), releasing corrosive and/or toxic gases and runoff. Flammable/toxic gases may accumulate in confined areas (basement, tanks, hopper/tank cars, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated or if contaminated with water. Substance may be transported in a molten form. | | Flammability and Explosibility | Notclassified | | Safety Profile | Poison by ingestion. A
corrosive irritant to skin, eyes, and mucous
membranes. When heated to decomposition it emits toxic fumes of VOx and Cl-. See also
VANADIUM COMPOUNDS and
HYDROCHLORIC ACID. | | Potential Exposure | Vanadium tetrachloride is used as a
fixative in textile dyeing and in the manufacture of other
vanadium compounds. | | Shipping | UN2444 Vanadium tetrachloride, Hazard class:
8; Labels: 8-Corrosive material. | | Incompatibilities | Vanadium tetrachloride is chemically
unstable, highly reactive with all forms of moisture, including
humidity, releasing corrosive hydrogen chloride and/or
chloride fumes. Keep away from light, UV, water, steam,
lithium, chlorine, trifluoride, alcohols, organic, and combustible
materials. Vanadium tetrachloride is a reactive
chemical and is an explosion hazard. See storage and handling
section. Corrosive to metals and may release flammable
hydrogen gas. Vanadium tetrachloride decomposes by
the action of light with the formation of Cl2 gas. Reacts as
an acid to neutralize bases. These neutralizations generate
heat. Usually does not react as either oxidizing agents or
reducing agents but such behavior is not impossible. May
catalyze organic reactions. |
