7632-51-1 Usage
Chemical Properties
Different sources of media describe the Chemical Properties of 7632-51-1 differently. You can refer to the following data:
1. Red liquid. Decomposes slowly to vanadium trichloride
and chlorine below63C. Soluble in absolute alcohol
and ether. Nonflammable.
2. 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.
Check Digit Verification of cas no
The CAS Registry Mumber 7632-51-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,3 and 2 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 7632-51:
(6*7)+(5*6)+(4*3)+(3*2)+(2*5)+(1*1)=101
101 % 10 = 1
So 7632-51-1 is a valid CAS Registry Number.

The slow addition of NO to a CCl4 solution of VCl4 reproducibly forms the known polymer [V(NO)3Cl2 ]n as a dark brown powder. Treatment of a CH2Cl 2 suspension of [V(NO)3Cl2]n with excess THF generates mer-(THF)3V(NO)Cl2 (1) which can be isolated as an orange crystalline material in 55% yield. The reaction of 1 with excess MeCN or 1 equiv of trimpsi (trimpsi = tBuSi(CH 2PMe2)3) provides yellow-orange (MeCN) 3V(NO)Cl2·MeCN (2·MeCN) and yellow (trimpsi)V(NO)Cl2 (3), respectively. A black, crystalline complex formulated as [NO][VCl5] (4) is formed by the slow addition of NO to neat VCl4 or by the reaction of excess CINO with neat VCl 4. Complex 4 is extremely air- and moisture-sensitive, and IR spectroscopy suggests that in solutions and in the gas phase it dissociates back into VCl4 and CINO. Reaction of 4 with excess [NEt 3(CH2Ph)]CI generates [NEt3(CH 2Ph)]2[VCl6]·2CH2Cl 2 (5·2CH2Cl2), which can be isolated as deep-red crystals in 51% yield. All new complexes have been characterized by conventional spectroscopic methods, and the solid-state molecular structures of 1, 2·MeCN, and 5·2CH2Cl2 have been established by single-crystal X-ray diffraction analyses.

Reactions of VCl3*3THF with RMgX (R = Ph, CH2SiMe3, C6F5) in various ratios have been studied.The stable compounds R3V*THF (R = CH2SiMe3, C6F5) were obtained.The chemical properties of R3V*THF, R4V*2L (R = CH2Ph, L = Et2O; R = C6F5, L = THF) and (Me3SiCH2)4V were investigated.Cleavage of the vanadium-carbonium ?-bond occurs in reactions with H2O, HCl and HgCl2.The insertion of carbon dioxide into the vanadium-carbon ?-bond was investigated.A scheme for the derivatives of tri- and tetravalent vanadium is proposed.Oxidative addition to (C6F5)3V*THF by Ph3CCl and VCl3*3THF was also studied.
