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 kcalmole for liquid methylene bisoxyamine and -103.0 kcalmole 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 F2CONF22, 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 F2CONF22 could be derived. The amount of sample available was too small to allow purification.
