Abstract
Abstract A new graphite intercalated antimony pentafluoride wherein the antimony pentafluoride is present up to 75% by weight. This compound is obtained as a black, free-flowing powder which is substantially resistant to hydrolysis under conditions which normally hydrolyze antimony pentafluoride. The graphite intercalated antimony pentafluoride is particularly useful for exchange reactions in the preparation of organic fluorides.
