Quenching of *UF6 (A state) by alkanes
Description
The removal of *UF6 (A state) molecules by selected alkanes has been investigated at 250C. 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. 3 figures, 1 table
