Abstract
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.
Claims8
A method for producing a metal chloride Mx+Clx−, the method comprising:
- providing a first gas including at least one of diphosgene and triphosgene,
- reacting a solid metal carbonate with the first gas to produce a metal chloride Mx+Clx−,
- wherein the metal M is selected from the group consisting of alkali metals and alkaline earth metals, and
- wherein x indicates the valence of the metal cation.
