UCC Shchekinoazot Ammonium Sulfate having the molecular formula (NH4) 2SO4 has a molecular weight of 132.14. Ammonium sulfate contains 21% nitrogen as ammonia and 24% sulfur as sulfur tetraoxide (form 21N-0-0-24S). It has white rhombohedral crystalline substance. Ammonium sulfate is easily soluble in water 38% solution is largely used as a liquid or mixed fertilizer. Ammonium sulfate is prepared commercially by reacting ammonia with sulfuric acid (H2SO4) with further recrystallization. Ammonium sulfate is often received as a co-product of cyclohexanoxime synthesis by a Beckmann rearrangement during caprolactam production.
