Abstract:

The novel NF4 salts NF42NiF6, NF42TiF6, NF4Ti2F9, NF4Ti3F13, NF4Ti6F25, and NF4SnF5 were synthesized and characterized. The NF42NiF6 and NF42TiF6 salts are of significant interest as ingredients in solid propellant NF3-F2 gas generators for chemical HF-DF lasers. The nickel salt represents the first successful combination of both an energetic perfluoro cation and anion in the form of a stable salt. The theoretical usable fluorine content of this salt is 68 percent higher than that obtainable with KF clinkered NF4BF4, the best previously known system. On thermal decomposition, one cc of solid NF42NiF 6 is capable of producing 1.5 times as much useful fluorine, i.e. in the form of NF3 and F2, as liquid F2 at -187 C. The metathetical NF4BF4 process was refined and high purity 99 metathetical NF4BF4 was obtained for the first time, thus eliminating the major drawback of the metathetical route. The process for the synthesis of the NF4SbF6 starting material was also improved by elimination of the cumbersome vacuum pyrolysis step. The usefulness of solid propellant NF3-F2 gas generators for the rapid destruction of magnetic tape was demonstrated. Information was obtained on the intermediates formed in the uv photolytic synthesis of NF4BF4. It was shown by esr spectroscopy that the BF4 radical is formed as the key intermediate during the low-temperature, uv-photolysis of the NF3-F2-BF3 system. The ESCA spectrum of NF4BF4 has been measured.
