Abstract : An experimental program was carried out on specific materials to determine the feasibility of utilizing high pressure to synthesize high-energy propellants. Pressurization experiments were conducted on hexanitroethane over the range of 25 to 100 kb(Kilobars) and from room temperature to 150 C with the objective of obtaining a low-vapor-pressure form. The Battelle-modified belt pressure apparatus and a Drickamer resistance cell were used for most of the experiments. A few runs were made with a Bridgman anvil device. Experiments to polymerize perfluoroguanidine was carried out both with the pure compound and solutions of perfluoroguanidine in a variety of solvents at ambient temperature and at pressure up to 25 kb. The perfluoroguanidine was recovered unchanged from some runs with the pure material. Higher pressures could be reached in fluorinated nickel capsules without explosion when perfluoroguanidine was dissolved in fluorocarbons. With perfluorobutene (C4F8) as a solvent, pressures of 10 to 15 kb were reached, and with perfluoropropane (C3F8), 15 to 20 kb. However, the perfluoroguanidine decomposed, and only carbon residues were recovered, along with the fluorocarbon and possibly CF4 or NF3. High-pressure experiments were carried out on noble gas-fluorine mixtures with the specific objective of synthesizing argon-fluorine compounds.
