INVESTIGATION OF THE THERMODYANMIC PROPERTIES OF PROPELLANT INGREDIENTS AND THE BURNING MECHANISMS OF PROPELLANTS
Abstract
The heat of formation of carbon tetrafluoride was derived as -223.2 plus or minus 0.6 kcal/mole from measurements of the heat of explosion of mixtures of cyanogen and nitrogen trifluoride. Measurements of the heat of explosion of mixtures of hydrogen and trifluoromethoxy difluoroamine were completed. The heat of formation of CF3ONF2 was calculated from the data as - 189.1 plus or minus 0.8 kcal/mole based on NBS Technical Note 270-1 value for HF (aq). This result implies a relatively strong bond energy E(N-O) = 53 kcal/mole, contrary to some evidence indicating E(N-O) = 35 kcal/mole. Errors were found in mathematical expressions used for the computerized calculations for experiments previously reported on Beane (BeH2) and ATBH (alane-terminated beryllium hydride polymer). The data were recomputed and now show a higher precision. The heats of formation were slightly revised as follows: Beane, from -5.3 to -5.0 kcal/mole; ATBH, from -33.7 to -35.7 to -35.7 kcal/100 grams. Work on DAHTP, Florox, and NF4BF4 is in progress. The preparation of pure, solvent-free TVOPA has been completed and it has been determined to contain only negligible benzene residue.
