Boron trifluoride etherate Chemical Properties,Usage,Production

Chemical Properties Colorless to brown fuming liquid General Description Boron trifluoride etherate is a fuming liquid. Boron trifluoride etherate may be corrosive to skin, eyes and mucous membranes. Boron trifluoride etherate may be toxic by inhalation. Upon exposure to water Boron trifluoride etherate may emit flammable and corrosive vapors. Boron trifluoride etherate is used as a catalyst in chemical reactions. Air & Water Reactions Highly flammable. Fuming liquid, immediately hydrolyzed by moisture in air to form hydrogen fluoride [Merck 11th ed. 1989]. Reactivity Profile Boron trifluoride etherate is a flammable, corrosive, moisture-sensitive liquid. When heated to decomposition Boron trifluoride etherate emits toxic and corrosive fluoride fumes. Reduction with lithium aluminum hydride in the attempt to prepare diborane caused an explosion [Chem. Eng. News, 1967, 45 (28), p. 7; 45 (21), p. 51]. Health Hazard May cause toxic effects if inhaled or ingested/swallowed. Contact with substance may cause severe burns to skin and eyes. Fire will produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution. Fire Hazard Flammable/combustible material. May be ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.
