General description about Molybdenum(V) Chloride (10241-05-1). It is a dark blue to black crystals.Also,it is a green-black odorless solid. it is toxic by ingestion and an irritant to skin. it may react with water to produce corrosive hydrochloric acid and toxic fumes.
Air & Water Reactions: Molybdenum(V) Chloride (10241-05-1) may react with water to produce corrosive hydrochloric acid and toxic fumes.
Reactivity Profile: It is a corrosive, hygroscopic solid, on contact with water or steam it decomposes to form hydrochloric acid. When heated to decomposition it 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].
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.
Fire Hazard: 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.
