12 paź 2016 · In order to clarify the equilibrium components in the hydrolysis solution of boron trifluoride (BF 3 -H 2 O), the BF 3 -H 2 O was prepared by mixing BF 3 -CH 3 OH with large amount of water, in which the stoichiometric concentration of BF 3 is less than 0.1 mol/L.
1 paź 2016 · Our investigation shows that the complexation bond BO between the BF3 and H2O units is strongly influenced by the larger electronegativity of Oxygen as compared to Nitrogen in BF3 ∙NH3.
NH,-BF3 system, i.e., B(3) B(4) N(3) N(4) F(l) F(2) H(l) H(2), and this minimum set of coordination numbers is used for all base-BF, systems, with the exception of pyridine, where N(2) N(3) is more appropriate, and dialkyl ether, where O(2) O(3) is used. The formation of B-N, H--N, and H--F bonds in the NH,-BF, system is an example of path-
10 lut 1995 · Ab initio Hartree-Fock and second-order Møller-Plesset calculations were performed on the molecular complex BF 3 H 2 O. Optimized geometries and total energies were determined using various basis sets, and the calculated vibrations and interaction energies were determined using total energies for BF 3 and H 2 O.

Boron trifluoride reacts with water to give boric acid and fluoroboric acid. The reaction commences with the formation of the aquo adduct, H 2 O−BF 3 , which then loses HF that gives fluoroboric acid with boron trifluoride.
1 sty 1976 · A simple apparatus was designed to determine the vapor density of BF 3 H 2 O mixtures at elevated temperatures. The compound BF 3 ·2H 2 O is completely dissociated above 200°C and pressures below one atmosphere.
