Abstract

A process for the recovery of ammonium sulfate from an aqueous solution of ammonium sulfate containing more than 25% by weight, based on the sulfate, of organic components, which are solid at room temperature, which comprises evaporating water from the aqueous solution in sufficient quantity to form an organic phase from the aqueous solution, separate said organic phase, and recover ammonium sulfate from the remaining aqueous solution, by crystallization.
