INVESTIGATION OF THE THERMODYNAMIC PROPERTIES AND THE DECOMPOSITION KINETICS OF PROPELLANT INGREDIENTS.
Abstract
The heat of formation of compound Delta was determined for Delta to be 2.5 + or -2.8 kcal./mole, and for the NF3, by two different methods, to average -31.6 + or -0.2 kcal./mole. Attempts to determine the heat of combustion of TVOPA were unsuccessful. The heat of combustion of P-BEP in oxygen was determined to be 3629.0 cal./g. The heats of solution of TVOPA and P-BEP in 2-octanone were determined as -4.6 and -3.0 cal./g. respectively. Work on the identification and removal impurities in CF3ONF2 is continuing. The heat of hydrolysis of lithium-doped, crystalline Beane has been completed. In support of the thermal measurements, N2F4, NF3, TVOPA and P-BEP were purified. CF3ONF2 and CF3OOCF3 were synthesized and then purified. The kinetics of decomposition and deflagration of a solid propellant containing Beane studied with a flash pyrolysis - kinetic spectroscopy apparatus above 2000 K. shows the existence of the subhydride and charged ion. Reaction with O2 is much slower with the ion than the subhydride. The study of the decomposition of NH4ClO4 shows the first step to be the dissociation to gaseous NH3 and HClO4. Subsequent reactions are the combustion of the various nitrogen species with the perchlorate species.
