使用上の注意
自然発生する塩化水素のため容器内圧が高く、急に開栓したり振り混ぜたりすると、内容物が噴出したり容器が破裂することがある。容器をよく冷却し、徐々に開栓すること。純度は金属ベースで差数法によって算出したもので、重量又は容量分析等の化学的方法によるものではありません。使用目的により、正確な含量が必要な場合は、それらの方法によって測定する必要があります。不活性ガス封入
化学的特性
Green-black solid, dark red as liquid orvapor.Hygroscopic,reacting with water and air. Soluble in dry ether,dry alcohol, and other organic solvents.
使用
Chlorination catalyst, vapor-deposited molyb-denum coatings, component of fire-retardant resins,brazing and soldering flux, intermediate fororganometallic compounds, e.g., molybdenum hex-acarbonyl.
空気と水の反応
MOLYBDENUM(V) CHLORIDE may react with water to produce corrosive hydrochloric acid and toxic fumes.
反応プロフィール
MOLYBDENUM(V) CHLORIDE is a corrosive, hygroscopic solid, on contact with water or steam MOLYBDENUM(V) CHLORIDE decomposes to form hydrochloric acid. When heated to decomposition MOLYBDENUM(V) CHLORIDE emits toxic fumes of molybdenum chlorides and metallic molybdenum [Lewis, 3rd ed., 1993, p. 892]. Explodes on contact with finely divided sodium [Berry D. H., Chem. Eng. News, 1989, 67(47), p. 2]. Reaction with finely divided sodium sulfide is violent, may lead to autoignition [Kaner, R. B., Nature, 1991, 349, p. 510].
危険性
Irritant.
健康ハザード
TOXIC; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death. Contact with molten substance may cause severe burns to skin and eyes. Reaction with water or moist air will release toxic, corrosive or flammable gases. Reaction with water may generate much heat that will increase the concentration of fumes in the air. Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
火災危険
Combustible material: may burn but does not ignite readily. Substance will react with water (some violently) releasing flammable, toxic or corrosive gases and runoff. When heated, vapors may form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapors may travel to source of ignition and flash back. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated or if contaminated with water.
安全性プロファイル
A poison. A corrosive
irritant to skin, eyes, and mucous
membranes. Reacts with moisture to form
hydrochloric acid. When heated to
decomposition it emits toxic fumes of Mo
and Cl-.
