Expandable graphite intercalation compounds, process for their preparation and their use

摘要

An expandable graphite intercalation compound having a controllable onset temperature comprises an intercalatable Lewis acid, optionally in combination with the solvent(s) used in its production and at least one organic compound. An Independent claim is also included for a process for the production of the graphite intercalation compound by reaction of graphite and the Lewis acid or in closed tube or in a suitable solvent, optional isolation, cleaning and drying of the intercalation compound, followed by reaction with the organic compound and isolation, cleaning and drying of the reaction product.
