Mass spectrometric study of the reaction of BF3 with B2O3; the identification and heat of formation of B2OF4
Keyword(s):
The reaction of BF3 with B2O3 in a molecular flow reactor has been studied with a mass spectrometer. Over the temperature range 930–1300 K the reaction has been found to produce B2OF4 with the stoichiometry[Formula: see text]From the temperature dependence of the equilibrium constant the enthalpy change for this reaction was determined to be 18.5 ± 3 kcal/mole and ΔHf0 (B2OF4) calculated to be −454 ± 2 kcal/mole at 1100 K.
