Abstract:

The heat of formation of the trimer BOF3g, which was reported in the preceding Quarterly Report, has been confirmed by transpiration experiments at 1000 deg K for the reaction B2O31 BF2g BOF3g. Employing the latest available thermodynamic data for the heats of formation of B2O3 and BF3 values for H sub f298K -567.8 or - 0.5 kcalmole and S sub 298K 89.9 or - 2 caldegmole for the trimer BOF3g are reported. Employing a new experimental technique, Molecular Flow Reaction Studies, a preliminary heat of formation H sub f298K of -145 or - 5 kcalmole is reported for the monomer BOF.
