Investigation of the Thermodynamic Properties of Propellant Ingredients
Abstract
The heats of formation of methylene bisoxyamine and methylene bisoxyamine diperchlorate were derived from oxygen bomb combustion calorimetry and solution calorimetry. Selected best values for the two compounds are -22.6 kcal/mole for liquid methylene bisoxyamine and -103.0 kcal/mole for crystalline methylene bisoxyamine diperchlorate. A technique for obtaining heats of formation of gaseous C-H-O-N-F compounds was developed, with CF3CN as a reference substance. When the technique was applied to F2C(ONF2)2, results deviated widely from the expected range. Chromatographic examination revealed a large fraction of F3CONF2 was present in the sample and no accurate result for F2C(ONF2)2 could be derived. The amount of sample available was too small to allow purification.
