Abstract: Different methods for the preparation of high purity NaAlCl4 are disclosed. The methods includes charging a feed having an intimate mixture of aluminum chloride, sodium chloride, and aluminum metal, to a reactor at an initial temperature less than about 80° C., carrying out a solid state reaction to form a solid NaAlCl4 at an intermediate temperature less than about 145° C., melting the formed solid NaAlCl4 at an elevated temperature greater than about 150° C. to produce molten phase NaAlCl4, holding the reactor at a raised temperature greater than about 165° C. to substantially complete formation of colorless NaAlCl4 and filtering the reactor contents at a final temperature greater than about 165° C.
