Abstract : The design principles of shock waves from detonating high explosives for the synthesis of energetic materials were applied to noble gas-fluorine chemistry. The goal was to synthesize noble gas fluorides. A shock wave, generated by a detonating explosive, heated a gas mixture to a high temperature, which ionized a fraction of the noble gas and dissociated a fraction of the fluorine. An important feature of the technique was rapid quenching of the product from high shock-wave temperatures. Quenching prevented the product from decomposing to elemental gases. Shock strengths of sufficient magnitude were generated by a cylindrically imploding detonation in nitroguanidine, which is a low-density explosive. Xenon difluoride was successfully synthesized from a mixture of 1 mole xenon to 3 moles fluorine, in quantity sufficient to be detected on a Hitachi mass spectrometer RMU 6D. The nitroguanidine density for this shot was 0.375 g/cc, which generated a reflected shock wave of such magnitude in the gas mixture to dissociate 1.6% of the fluorine.
