Method for separating ammonium sulfate from an aqueous solution of ammonium bisulfate and ammonium sulfate

摘要

A method is disclosed for separating ammonium sulfate from an aqueous solution of ammonium bisulfate and ammonium sulfate, and, in particular, where the aqueous solution additionally contains organics from a synthesis reaction. Separation is effected by the addition of an alcohol, preferably methanol, to the aqueous solution in an amount sufficient to precipitate substantially all of the ammonium sulfate and thereafter removing said precipitate from the solution.
