Ammonium Sulfate - an overview | ScienceDirect Topics

Sulfuric acid (H 2 SO 4) is important in the production of fertilizers (e.g., ammonium sulfate (sulfate of ammonia), (NH 4) 2 SO 4, and superphosphate, Ca(H 2 PO 4) 2, which is formed when rock phosphate is treated with sulfuric acid). Sulfuric acid is manufactured at the site using the well-known contact process.

Ammonium sulfate | (NH4)2SO4 - PubChem

Ammonium sulfate is an inorganic sulfate salt obtained by reaction of sulfuric acid with two equivalents of ammonia.A high-melting (decomposes above 280℃) white solid which is very soluble in water (70.6 g/100 g water at 0℃; 103.8 g/100 g water at 100℃), it is widely used as a fertilizer for alkaline soils. It has a role as a fertilizer.

Ammonium sulfate - Wikipedia

Ammonium sulfate is made by treating ammonia, often as a by-product from coke ovens, with sulfuric acid: 2 NH3 + H2SO4 → (NH4)2SO4A mixture of ammonia gas and water vapor is introduced into a reactor that contains a saturated solution of ammonium sulfate and about 2 to 4% of free sulfuric acid at 60 °C. Concentrated sulfuric acid is added to keep the solution acidic, and to retain its level of free acid. The heat of reaction keeps reactor temper…

Gypsum and its role in trapping ammonia gas

Aug 01, 2014· Gypsum has more sulfate available so it can trap more ammonium than superphosphate. The more product blended in the soil, the more ammonia was trapped. The key is to predict the amount of nitrogen per ton of material that will volatilize and then apply enough gypsum to capture that ammonia into a stable ammonium sulfate form.
