| Hazard Information | Back Directory | [General Description]
BORON TRIFLUORIDE DIETHYL ETHERATE(109-63-7) is a fuming liquid. BORON TRIFLUORIDE DIETHYL ETHERATE(109-63-7) may be corrosive to skin, eyes and mucous membranes. This material may be toxic by inhalation. Upon exposure to water BORON TRIFLUORIDE DIETHYL ETHERATE(109-63-7) may emit flammable and corrosive vapors. BORON TRIFLUORIDE DIETHYL ETHERATE(109-63-7) is used as a catalyst in chemical reactions. | [Reactivity Profile]
BORON TRIFLUORIDE DIETHYL ETHERATE is a flammable, corrosive, moisture-sensitive liquid. When heated to decomposition BORON TRIFLUORIDE DIETHYL 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]. | [Air & Water Reactions]
Highly flammable. Fuming liquid, immediately hydrolyzed by moisture in air to form hydrogen fluoride [Merck 11th ed. 1989]. | [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. | [Potential Exposure]
Used as a catalyst. | [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. | [First aid]
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts the
skin, remove contaminated clothing and wash immediately
with soap and water. Seek medical attention immediately.

If this chemical has been inhaled, remove from exposure,
begin rescue breathing (using universal precautions, including
resuscitation mask) if breathing has stopped and CPR if
heart action has stopped. Transfer promptly to a medical
facility. When this chemical has been swallowed, get
medical attention. If victim is conscious, administer water
or milk. Do not induce vomiting. Medical observation is
recommended for 24 to 48 hours after breathing overexposure,
as pulmonary edema may be delayed. As first aid for
pulmonary edema, a doctor or authorized paramedic may
consider administering a drug or other inhalation therapy. | [Shipping]

Flammable liquid. | [Incompatibilities]
Reacts with air forming corrosive hydrogen
fluoride vapors. Incompatible with oxidizers (may
cause fire and explosion), water, steam or heat, forming

magnesium tetrahydroaluminate. Mixtures with phenol
react explosively with 1,3-butadiene. Presumed to form
explosive peroxides. | [Physical properties]

Lewis acid reagent with broad application
Catalyst used in the preparation of cyclopentyl- and cycloheptyl[b]indoles from aryl cyclopropyl ketones via [3+2] cycloaddition. | [Hazard]

| Questions And Answer | Back Directory | [Chemical Properties]
Colorless to brown fuming liquid. | [uses]
Boron trifluoride diethyl etherate is used as a Lewis acid catalyst in Mukaiyama aldol addition, alkylation, acetylation, isomerization, dehydrations and condensation reactions. It is involved in the prepattion of polyethers in polymerization reactions. As a catalyst, it is used in the preparation of cyclopentyl- and cycloheptyl[b]indoles and other diborane. It is also used in sensitive neutron detectors in ionization chambers as well as monitoring radiation levels in earths atmosphere. | [Preparation]
Boron trifluoride gas, produced by heating the sulfuric acid, calcium fluoride (fluorite) and boric acid together, reacts with ether boron to produce the trifluoride etherate crude product, thus we can refine it to get the finished product. The consumption of raw material is as followed: boric acid (≥98%), 560kg/t; calcium fluoride(≥90%) 1150kg/t; fuming sulfuric acid (104.5%), 4100kg/t; ether(≥99%) 725kg/t.
In absorption method shown in the chemical equations as followed, diethyl ether absorb boron trifluoride gas, produced by heating the sulfuric acid, calcium fluoride (fluorite) and boric acid together, to produce trifluoride etherate crude complex compound by vacuum distillation.
