Ammonium sulfate | (NH4)2SO4 - PubChem

The conventional caprolactam process produces 2.5 - 4.5 tons of ammonium sulfate per ton of lactam. Of that, 0.3 - 2.8 tons are formed in the hydroxylamine - oximation stage and approx. 1.7 tons in the Beckmann rearrangement stage. Crystallizers are used in the evaporation of ammonium sulfate solutions that result from caprolactam production.
