Abstract
The present technology relates to systems, devices and methods for the production of highly dehydrated and pure magnesium chloride and aluminum chloride.
Claims20
A method of dehydrating magnesium chloride hydrate bearing from about 0.01 to 6 waters of hydration comprising:
- a) adding said magnesium chloride hydrate to a molten salt composition comprising anhydrous magnesium chloride over a first time period to obtain a mixture;
- b) holding the mixture for a second time period;
- and
- c) separating the precipitated solids from the mixture;
- thereby obtaining a molten salt composition enriched in anhydrous magnesium chloride.
2 more elements
A process for purifying a molten electrolyte comprising magnesium chloride, the process comprising:
- c) contacting the molten electrolyte with a getter metal selected from the group consisting of calcium, aluminum, zinc, tin, copper, magnesium, manganese, iron and sodium;
- and
- d) removing the insoluble materials;
- thereby obtaining a purified molten electrolyte.

A method of dehydrating aluminum chloride hydrate bearing from about 0.01 to 6 waters of hydration comprising:
- d) adding said aluminum chloride hydrate to a molten salt composition comprising anhydrous aluminum chloride over a first time period to obtain a mixture;
- e) holding the mixture for a second time period;
- and
- f) separating the precipitated solids from the mixture;
- thereby obtaining a molten salt composition enriched in anhydrous aluminum chloride.
