Chemische Eigenschaften
Green-black solid, dark red as liquid orvapor.Hygroscopic,reacting with water and air. Soluble in dry ether,dry alcohol, and other organic solvents.
Verwenden
Chlorination catalyst, vapor-deposited molyb-denum coatings, component of fire-retardant resins,brazing and soldering flux, intermediate fororganometallic compounds, e.g., molybdenum hex-acarbonyl.
Air & Water Reaktionen
MOLYBDENUM(V) CHLORIDE may react with water to produce corrosive hydrochloric acid and toxic fumes.
Reaktivit?t anzeigen
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].
Hazard
Irritant.
Health Hazard
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.
Brandgefahr
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.
Sicherheitsprofil
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-.
