Notes:
The removal of *UF6 (A state) molecules by selected alkanes has been investigated at 25°C. The following rate constants (units of 1011 l/mol·sec) were evaluated: iso-C4F10, 0.0432 ± 0.0115; n-C4F10, 0.0764 ± 0.020; C2F6, 0.0192 ± 0.0052; CH4, 0.0612 ± 0.0061; C2H6, 3.78 ± 0.60; C3H8, 5.08 ± 0.60; n-C4H10, 5.05 ± 0.78; iso-C4H10, 4.17 ± 1.15; neo-C5H12, 6.59 ± 0.93; CF3—CH3, 0.0385 ± 0.0056; CF2H—CF2H, 0.0729 ± 0.0074; and CF2H—CFH2, 0.149 ± 0.015. The perfluoro-alkane quenching of *UF6 proceeds via a physical mechanism. The other alkane quenching reactions are consistent with a chemical mechanism also contributing in varying degrees which may involve removal of two hydrogens from the alkane.
