The parameters governing the reactivity of various compounds with graphite have been poorly understood . The role of free halogen acting as an oxidant or catalyst has been debated (FeCl3 and AlCl3). The frequent reaction of many, but not all, Lewis acids with graphite has been noted (PF5 vs. AsF5). In this paper, an impressive correlation between the gas phase heats of oxidation among families of reactants and the reaction or lack of reaction with graphite is given. This correlation of some 30 reactions allows predictions for the reaction of approximately 20 other reagents. This correlation with heats of gas phase oxidations unifies the earlier disparate criteria for reaction into a single criterion that a particular level of oxidation is essential for reaction with graphite.
