The NH3-BF3 and MeNH,-BF3 systems The analysis of the NH3-BF, system by the coordination model begins by considering all possible interactions be- tween the atoms of ammonia and boron trifluoride, of which the strongest will most likely involve B-N, H--N, and H--F bonds. The model is tolerant of higher coordination num-

In order to clarify the equilibrium components in the hydrolysis solution of boron trifluoride (BF3-H2O), the BF3-H2O was prepared by mixing BF3-CH3OH with large amount of water, in which the stoichiometric concentration of BF3 is less than 0.1 mol/L.
1 mar 1992 · It was found that I11 is significantly stronger than indicated by earlier measurements con- ducted by the classical Hammett method based on UV-visible spectroscopy. The mixtures with about 1.25 mol of water per mol of BF3 or less are stronger than pure sulfuric acid and are therefore superacidic.
It is shipped as a nonliquefied compressed gas at varying pressures up to 2000 psig (13 790 kPa). Boron trifluoride re acts readily with water with the evolution of heat to form the hydrates BF3·H20 and BF3·2H20, which are relatively strong acids.
In the BF 3 affinity scale, Lewis bases' BF3 affinities are equal to the negative enthalpy change for formation of a solution phase adduct between the base and gaseous BF 3. The reaction is:
