PRODUCTION OF ALKALI METAL SULFATES Abstract Alkali metal sulfates are produced from an aqueous solution containing alkali metal hydrogen sulfate which comprises contacting the aqueous solution of alkali metal hydrogen sulfate with a hydrophilic solvent, the hydrophilic solvent being effective to extract at least a portion of the sulfuric acid formed as the alkali metal hydrogen sulfate is converted to alkali metal sulfate in the solution, together with at least a portion of the water present; permitting the alkali metal sulfate solid to crystallize; and recovering the solid alkali metal sulfate product. The hydrophilic solvent may then be extracted and separated from the sulfuric acid with a hydrophobic solvent and both solvents can be recovered and recycled.
