六氟化硫是一种高度化学惰性气体，具有多种重要的工业应用。即使在几百摄氏度下，它也能稳定地抵抗熔融碱、氧和氨。在这项工作中，金属（Li-Cs，Sr，Ba，Eu，Yb）溶解在液氨和SF6之间的反应，导致单或二价的氟化物和硫化物。为此，将SF6通入相应金属在液氨中的冷却溶液中。通过粉末X-射线衍射和红外光谱确认了产物的身份。这些反应可能导致一种廉价和有效的处置方法，目前储存的SF6量，为可能产生的H2S和HF。
Sulfur hexafluoride is a highly chemically inert gas with several important industrial applications. It is stable against fused alkali, oxygen and ammonia, even at several hundred degrees Celsius. In this work, the reactions between metals (Li-Cs, Sr, Ba, Eu, Yb) dissolved in liquid ammonia and SF6 are reported, leading to mono- or bivalent fluorides and sulfides. To this end, SF6 was passed into a cooled solution of the respective metal in liquid ammonia. The identity of the products was confirmed by powder X-ray diffraction and IR spectroscopy. The reactions could lead to a cheap and effective disposal method of the present amounts of stored SF6, for possible generation of H2S and HF.
