Radiochemical studies on graphite ferric chlorideLazo, Robert Martin January 1950 (has links)
Graphite ferric chloride, C₁₂FeCl₃, was prepared by heating anhydrous ferric chloride with graphite at 305°C. The purified compound containing 53% ferric chloride was not attacked by hot 6N hydrochloric acid or 6N sodium hydroxide solutions. X-ray diffraction measurements gave a powder pattern which was distinctly different from that of either graphite or ferric chloride and from which it was apparent that no free ferric chloride existed in the compound. The separation of the graphite layer-planes was increased from 3.36 to 9.4Å by the intercalation of the ferric chloride molecules.
Tests for exchange between C₁₂FeCl₃ and Fe⁺⁺⁺ ion were made using radioactive Fe⁵⁹. In no instance was any measurable exchange observed. The compound was subjected to neutron irradiation and the Szilard-Chalmers yield of separable activity calculated and identified. The separated portion contained less than 1% of the total activity and consisted of Fe⁵⁹, P³² and S³⁵, free of detectable radiation decomposition products. The active Fe portion was separated by ether extraction.
The lack of exchange and the low Szilard-Chalmers yield are both attributed to the formidable steric hindrance effects which result from the configuration of the "stacked layers" structure for graphite ferric chloride. / Science, Faculty of / Chemistry, Department of / Graduate

Studies on the ferric chloride-graphite systemBartlett, Michael William January 1967 (has links)
Isotherms of the ferric chloride-graphite system have been determined at 300°C, 310°C, and 350°C. It was found that C₇FeCl₃ is formed at all three temperatures, and in addition Cl₁₂FeCl₃ is formed at 350°C.
C₇FeCl₃ has been isolated by preparing it in a bomb. Mossbauer studies on it showed that electron transfer is from graphite to iron chloride, and that all of the iron is in the same oxidation state.
It has been shown that intercalated ferric chloride can be reduced to ferrous chloride by hydrogen at 375°C.
Studies on graphite containing ferric chloride or chromyl chloride have shown that the threshold pressure for intercalation of Br₂, ICl, or CrO₂Cl₂ is higher than for pure graphite.
It has been found that the uptake of chromyl chloride by graphite is dependent on the rate of pressure increase, and that in addition natural crystals of graphite vary in their reactivity with chromyl chloride. / Science, Faculty of / Chemistry, Department of / Graduate
