Thermodynamics of Reactions Involving Light Metal Oxides and Propellant Gases

Abstract

The heat of formation of the trimer (BOF)3(g), which was reported in the preceding Quarterly Report, has been confirmed by transpiration experiments at 1000 deg K for the reaction B2O3(1) + BF2(g) = (BOF)3(g). 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 kcal/mole and S sub 298K = 89.9 + or - 2 cal/deg/mole for the trimer (BOF)3(g) are reported. Employing a new experimental technique, Molecular Flow Reaction Studies, a preliminary heat of formation H sub f298K of -145 + or - 5 kcal/mole is reported for the monomer BOF.
