SYNTHESIS, PROPERTIES, AND STRUCTURE OF INTERCALATED GRAPHITE FLUOSULFONATE FLUORIDES

Graphite flusulfonate fluorides of the composition C2Fx-y(SO3F)(y) (x + y approximate to 1) have been synthesized. The new compounds can be treated as derivatives of graphite fluorides C2Fx(x approximate to 1) in which approximately 1/50 of the F atoms have been replaced by SO3F groups.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 b y X-ray phase analysis, IR spectroscopy, mass spectrometry, and thermo graphy. The ability of the intercalates to absorb various substances i s investigated If is shown that the introduction of a few SO3F groups into the C2Fx matrices significantly changes the physicochemical prope rties and the structure of intercalates; in particular, for intercalat es 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 molecul es makes intercalates resemble zeolites in properties.
