METHOD OF OBTAINING GRAPHITE-BASED THEROEXPANDABLE COMPOUND |
摘要 |
FIELD: chemistry. ^ SUBSTANCE: invention can be used to make carbonaceous adsorbents. Iodine heptafluoride is frozen onto a graphite-containing powdered material from a gas phase with pressure lower than equilibrium pressure over liquid-phase iodine heptafluoride. The graphite-containing powdered material is then treated with liquid-phase iodine heptafluoride to obtain an intercalation compound of fluorinated graphite by defrosting the two-component mixture to temperature of 7-25C and then holding at equilibrium pressure of iodine heptafluoride vapour over the liquid phase. The remaining liquid phase is frozen out from the graphite-containing powdered material. The obtained powdered intercalation compound of fluorinated graphite is thermally treated in a muffle furnace. ^ EFFECT: invention increases the factor of increase of volume, lowers the temperature for onset of expansion using a simple and safe method which does not require complex equipment. ^ 1 tbl, 4 dwg |
