Gas-phase chemical reactivity of CFC-114 and potential replacements: Part 3, Reactivity of n-C sub 4 F sub 10 with F sub 2 and UF sub 6
The DOE gaseous diffusion plant complex makes extensive use of CFC-114 as primary coolant. As this material is on the Montreal Protocol list of materials scheduled for production curtailment, a substitute must be found. In addition to physical cooling properties, the gaseous diffusion application imposes requirements of chemical inertness to fluorinating agents that are somewhat unique. A series of studies has therefore been undertaken to evaluate the gas-phase chemical reactivity of potential alternate coolants. This report examines the reactivity of normal perfluorobutane (n-C{sub 4}F{sub 10}) with UF{sub 6} and F{sub 2} at selected reference conditions (2 to 10 Torr partial pressure of each reactant, 150{degrees}C). At the reference conditions, a very slight degree of reactivity was observed, but much less than the observed reactivity of the reference coolant, CFC-114. 12 refs., 9 figs., 12 tabs.
