The invention relates to the use of a porous organometallic framework material containing at least one first and optionally one second organic compound. At least the first organic compound at least coordinately binds, to at least one metal ion in an at least partial two-toothed manner. The at least one metal ion is Mg (II) and the first organic compound derives from formic acid and the second organic compound derives from acetic acid, for storing or separating methane. The invention also relates to a formiate and acetate-magesium based porous organometallic framework material and to the production thereof.
Abstract:
The invention relates to a method for catalytically reacting an organic compound with a hydroperoxide in at least one reactor while using at least two zeolite catalysts that differ from one another. The invention is characterized in that at least two of the different zeolite catalysts are used while being spatially separated from one another.
Abstract:
