Inorganic Halogen Oxidizer Research.
Abstract
Major breakthroughs were achieved in the field of NF4(+) chemistry and solid propellant NF3-F2 gas generators for chemical HF-DF lasers. The novel concept of a self-clinkering NF3-F2 generator, based on the new (NF4)2 SNF6 salt, was developed, and a feasible method of producing (NF4)2 SnF6 by metathesis was established. Work on the UV-photolysis of NF3-F2-Lewis acid systems resulted in an economic process for the production of pure NF4BF4 on a pound scale, thus providing the material required for its development as a NF3-F2 gas generator. The following novel NF4(+) salts have been synthesized: (NF4)2SnF6, (NF4)2GeF6, NF4SnF5, NF4GeF5, NF4PF6, NF4BiF6, and NF4Bi2F11. These and some of the known NF4(+) salts have been or are presently being characterized. The concept of displacing NF3 and F2 from NF4BF4 by low-melting eutectic mixtures was examined, and the syntheses of (NF4)2SiF6, NF4HF2, (N2F3)2GeF6, and N2F3BF4 were attempted. Low-temperature UV-photolysis was also successfully applied to the synthesis of the novel dioxygenyl salt O2+GeF5-, which was thoroughly characterized. Evidence was obtained for a metastable gaseous species at room temperature containing an infrared active O-O multiple bond. An improved oxidizer for closed-cycle submarine propulsion systems was found and proposed to DARPA for further study. The fluorination of UF4 and UO2F2 to UF6 by N2F2 was briefly investigated. Study of the PtF6-XeOF4 reaction system and the crystal structure determination of (BrF2)2 GeF6 was completed.
