Anionic Reactions Degrading SF6 Using Metals: Insights From the Gas Phase

Description
Summary:ABSTRACT Alkali metals have been used to degrade SF6 in liquid ammonia. The products include metal fluorides. In this study, we reacted K− and Ag− with SF6 in a triple quadrupole mass spectrometer. The atomic metal anions were formed by in‐source collision‐induced dissociation (CID) of their respective oxalate salts as previously described by our group. The only two reaction products observed were SF6− and SF5−. At low collision energy, the latter was deduced to be formed via an ion by the metal of F from SF6− formed by electron transfer in the encounter complex between the metal anion and neutral SF6. As the collision energy was increased, there was evidence of a CID contribution to SF5− directly from SF6−.
