Flammable

5.1-18.2%(V)

Highly flammable. Fuming liquid, immediately hydrolyzed by moisture in air to form hydrogen fluoride [Merck 11th ed. 1989].

Boron trifluoride diethyl ether complex is a stable, highly flammable, colourless to brown fuming, corrosive liquid with a sharp pungent odour. It forms explosive peroxides in contact with air or oxygen. It reacts exothermically with water to form extremely flammable diethyl ether and toxic, corrosive boron trifluoride hydrates. The chemical is incompatible with bases, amines, and alkali metals. It immediately gets hydrolysed by moisture in air to form hydrogen fluoride. Boron trifluoride diethyl ether has applications in chemical laboratory as a catalyst in chemical reactions.

The compound is highly toxic by inhalation. Skin contact causes burns.

Reacts with air forming corrosive hydrogen fluoride vapors. Incompatible with oxidizers (may cause fire and explosion), water, steam or heat, forming corrosive and flammable vapors. Peroxide containing etherate reacts explosively with aluminum lithium hydride, magnesium tetrahydroaluminate. Mixtures with phenol react explosively with 1,3-butadiene. Presumed to form explosive peroxides.

UN 2604

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.
