A method for producing metal chloride Mx+Clx? includes reacting metal carbonate in solid form using phosgene, diphosgene and/or triphosgene to form metal chloride Mx+Clx?, wherein the metal M is selected from the group containing alkali metals, alkaline earth metals, Al and Zn, Li and Mg, or Li, for example, and x corresponds to the valency of the metal cations. An apparatus for performing such method is also disclosed.

The invention relates to a method for producing aprotic solutions that contain zinc bromide and lithium bromide, the reaction of the reactants to the product being carried out as a one-pot reaction.
