The effect of calcium, iron, silicon, titanium and vanadium was determined on the rates of carbon-oxygen, carbon-carbon dioxide and carbon-steam reactions. A general equation describing the weight loss-exposure time relationship was also developed for all reaction systems investigated.
H. P. Boehm and J. Pflugmacher (Institut fur anorgunische Chemie d.er Universitat Munchen, Germany). The formation of intercalation compounds of graphite and carbons is influenced qualitatively and quantitatively by lattice defects, depending on the nature of the intercalated material. Bromine intercalation is very sensitive to lattice defects, whereas potassium is intercalated also by poorly organized carbons. AlCls and FeCl, are in between these extremes. Bromine intercalation isotherms may serve as "fingerprints" of graphites. Measurement of the oxidation kinetics with Simon reagent as introduced by Oberlin and Mering will be critically reviewed.

It is considered that one requirement (among others) for the Dubinin equation to linearise adsorption isotherms of carbons is the forces of adsorption should be essentially non-polar, Van der Waals forces. To test this assumption molecules with permanent dipoles, e.g. NH3 and H2S have been adsorbed
