Beschreibung
Zusammenfassung:	A process for preparing a catalyst which process comprises preparing a mi xture comprising iron oxide and at least one Column 1 metal or compound ther eof, wherein the iron oxide is obtained by heating a mixture comprising an i ron halide and at least 0.05 millimole of a metal chloride that is converted to a metal oxide under the heating conditions per mole of iron; a catalyst made by the above described process; a process for the dehydrogenation of an alkylaromatic compound which process comprises contacting the alkylaromatic compound with the catalyst; and a method of using an alkenylaromatic compou nd for making polymers or copolymers, in which the alkenylaromatic compound has been produced by the dehydrogenation process.
