INVESTIGATION OF THE THERMODYNAMIC PROPERTIES OF PROPELLANT INGREDIENTS AND THE BURNING MECHANISMS OF PROPELLANTS
Abstract
The heat of hydrolysis of lithium doped LMH-2 has been completed and the heat of formation calculated to be -5.25 kcal/mole. A preliminary value for the heat of formation of gaseous CF3ONF2 was derived from the heat of explosion of mixtures of the sample and hydrogen. The result, -188.4 + or - 2.0 kcal/mole, is about the expected value for this compound. Work on DAHTP, TVOPA and liquid polymer is continuing. In the synthesis work, the purification of TVOPA has been continued and a method has been developed which gives satisfactory results. Additional pure CF3ONF2 has been prepared for heat of formation measurements. A synthesis procedure for CF3NF2 has also been developed. The volatilization and combustion of elemental boron has been studied by flash pyrolysis - kinetic spectroscopy. The species B and B2 were detected during the volatilization of the element. The combustion of boron in oxygen showed the presence of Bo, BO2, B2O2 and B2O3 during the reaction. The flash pyrolysis of H3BO3(HOBO.H2O) showed the presence of OH, and BO2 indirectly that the species HOBO may dissociate to H and BO2 at high temperatures. There is some evidence that B2O3 dissociates to BO and BO2 at temperatures above its boiling point. (Author)
