Abstract
Graphite fluosulfonate fluorides of the composition C2Fx−y(SO3F)y (x+y≈1) have been synthesized. The new compounds can be treated as derivatives of graphite fluorides C2Fx(x≈1) in which approximately 1/50 of the F atoms have been replaced by SO3F groups. The intercalates based on the new matrices have been studied by X-ray phase analysis, IR spectroscopy, mass spectrometry, and thermography. The ability of the intercalates to absorb various substances is investigated. It is shown that the introduction of a few SO3F groups into the C2Fx matrices significantly changes the physicochemical properties and the structure of intercalates; in particular, for intercalates of stage II structure this expands the scope of substances that can penetrate into interlayer spacings. The dependence of the penetration ability of the substances on the van der Waals sizes of their molecules makes intercalates resemble zeolites in properties.
