Title: Manufacture of fluorine compounds
IPC: C01B21/084
Filed: 1963-03-07
Abstract: The invention comprises the compound trifluoroamine oxide F3NO which has a boiling point of about - 89 DEG  C. and a melting point of about - 161 DEG C.; under normal conditions it is a colourless gas. The compound is made by subjecting a mixture of OF2 and NF3 to the action of an electric discharge at low pressure and at a temperature low enough to condense out the product; a mixture of elemental nitrogen and elemental fluorine may be used instead of the NF3.  In examples, a mixture of the reactant gases, together with helium, is fed to a U-shaped quartz discharge tube provided with nickel electrodes, a pressure of 10-15 mm. Hg and a temperature of - 196 DEG C. being maintained in the tube.  The product is vaporized so as to decompose the by-product O2F2 into oxygen and fluorine which do not recombine on cooling and are removed as gases; other by-products formed are N2O, SiF4, NO2, N2O3, NOF and (NO)2SiF6. Trifluoroamine oxide may be separated by fractional condensation, and may be used as an oxidizer for missile fuels or as an additive to N2O4 oxidizer.
