most nonmetals; dissolves and/or reacts with
many organic compounds; hydrolyzes in moisture.
使用
Vanadium(V) trichloride oxide is used as a catalyst in olefin polymerization reaction, especially for the production of ethylene-propylene rubber. It is also used to synthesis organovanadium compounds and as a mordant in dyeing. It acts as a precursor to prepare vanadium pentoxide, vanadyl dichloride and dioxovanadium monochloride. Further, it serves as a reagent and a strong oxidizing agent in organic synthesis.
空気と水の反応
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.
反応プロフィール
VANADIUM(V) TRICHLORIDE OXIDE 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].
健康ハザード
Inhalation of vapor causes irritation of nose and throat. Ingestion causes irritation of mouth and stomach. Contact with eyes or skin causes severe irritation.
火災危険
Special Hazards of Combustion Products: Irritating fumes of hydrogen chloride may form in fires.
安全性プロファイル
Poison by ingestion. A
corrosive irritant to skin, eyes, and mucous
membranes. Explosive reaction with
sodmm. Violently hygroscopic. Violent
reaction with rubidium (at 6OoC), potassium.
When heated to decomposition it emits
toxic fumes of VOx and Cl-. See also
VANADIUM COMPOUNDS and
HYDROCHLORIC ACID.
純化方法
VOCl3 should be lemon yellow in colour. If it is red, it may contain VCl4 and Cl2. Fractionally distil it, and then redistil it over metallic Na, but be careful to leave some residue because the residue can become EXPLOSIVE in the presence of the metal. USE A SAFETY SHIELD and avoid contact with moisture. It readily hydrolyses to vanadic acid and HCl. Store it in a tightly closed container or in sealed ampoules under N2.
