Chemistry & industry
Applications
UsesCatalyst in acetylation, alkylation, polymerization, dehydration, and condensation reactions.
UsesBoron 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.
General DescriptionBoron 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.
Preparation methods
PreparationBoron 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.3H2SO4+2H33BO3+3CaF2→2BF3+3CaSO4+6H2OBF3+(C2H5)2O→(C2H5)2O•BF3
PreparationBoron trifluoride etherate is prepared by the reaction of vapors of boron trifluoride with that of anhydrous diethyl ether:BF3 (g) + (C2H5)2O (g) → (C2H5)2OBF3.
