BUT BF3 reacts with the lewis base OH- to form H[BF3OH] and thus affects the pH of the solution - effectivly making the solution more acidic. A similar effect is seen in the boric acid, B(OH3), which forms H[B(OH)4] in water.
29 lis 2015 · If BF 3 stripped an H atom off a water molecule, it would technically leave OH-in the solution, and actually raise the pH instead. BF 3 is a Lewis acid. Why would it raise the pH?
Boron trifluoride is the inorganic compound with the formula BF3. This pungent, colourless, and toxic gas forms white fumes in moist air. It is a useful Lewis acid and a versatile building block for other boron compounds. The geometry of a molecule of BF3 is trigonal planar. Its D 3h symmetry conforms with the prediction of VSEPR theory.
BF 3 supported on silica provides good accessibility for the reactants to the active site and is a mild strength solid acid [72]. Both BF 3-SiO 2 and nano BF 3-SiO 2 were found to be efficient mild acid catalysts for the syntheses of heterocyclic compounds.
BF3 is a non-flammable compressed gas packaged and shipped in cylinders under high pressure. It is one of the strongest Lewis acids, which are also known as electron pair acceptors. In gas form, it reacts with chemicals containing oxygen, nitrogen, sulfur, and other electron pair donors to form addition or coordination compounds.
Acylation of beta-caryophyllene, a sesquiterpene hydrocarbon with acetic anhydride, was carried out under mild catalytic conditions using Lewis acids such as BF3.Et2O, ZnCl2, FeCl3, I2 and AlCl3 as catalysts. Among these, BF3.Et2O was found to catalyse the reaction most efficiently
