Abstract

A process for preparing metal chloride Mx+Clx−, in which metal carbonate in solid form is reacted with a chlorinating agent selected from chlorine and oxalyl chloride to give metal chloride Mx+Clx−, where the metal M is selected from the group of the alkali metals, alkaline earth metals, Al and Zn, Li and Mg, or Li, and x corresponds to the valency of the metal cation, and wherein metal M is additionally added as a reactant to the metal carbonate/chlorinating agent reaction.
