Thermodynamics of Reactions Involving Light Metal Oxides and Propellant Gases

Abstract

Employing a new experimental technique, molecular flow reaction studies, a heat of formation (H sub f298K) of - 142 + or - 3 kcal/mole is reported for the molecule BOF(g). The reaction B2O3(1) + BF3(g) equals (BOF)3(g 0 was employed for this study. Earlier transpiration studies yielded values for H sub f298K of - 567.8 + or - 0.5 kcal/mole and S sub 298K of 89.9 + or - 2 cal/degrees/mole for the trimer BOF3(g).
