General Description

A fuming liquid. Corrosive to skin, eyes and mucous membranes. May be toxic by inhalation. Used as a catalyst in chemical reactions.

Air & Water Reactions

Highly flammable. In moist air forms dense white pungent fumes, corrosive to skin, avoid inhalation [Merck 11th ed. 1989]. Upon exposure to water may emit flammable and corrosive vapors.

Reactivity Profile

Boron trifluoride dimethyl etherate is a flammable, corrosive, and toxic liquid, moisture-sensitive. Emits toxic fluoride fumes when heated to decomposition [Lewis, 3rd ed., 1993, p. 189].

Health Hazard

Boron trifluoride dimethyl etherate is highly toxic by inhalation.

Fire Hazard

Fire may produce irritating or poisonous gases. Flammable/combustible material which may be ignited by heat spark or flame. Vapors may travel to a source of ignition and flash back. Container may explode in heat of fire. Vapor explosion hazard indoors, outdoors, or in sewer. Runoff to sewer may create fire or explosion hazard. When heated to decomposition, Boron trifluoride dimethyl etherate emits toxic fumes of fluorides.

TEMPERATURE EFFECTS OF THE MOLECULAR STRUCTURE OF DIMETHYL ETHER-BORON TRIFLUORIDE AS STUDIED BY GAS-PHASE ELECTRON DIFFRACTION

The molecular structure of dimethyl ether-boron trifluoride (CH3)2O.BF3 has been studied at temperatures of 16, 30 and 70 deg C by gas-phase electron diffraction.The molecule exists in a staggered conformation with an O-B distance of 1.75 +/- 0.02 Angstroem, an angle between the O-B bond and the COC plane of 40 +/- 8 deg and an FBF angle 117 +/- 2 deg at each temperature.However, the F-B and C-O distances are found to decrease with increasing temperature, and appear to converge to the corresponding values of the component molecules.The temperature dependence of the B-F and C-O distances is surprisingly large, compared with those in other molecules.
