Ammonium sulfate is our flagship export product. It is a high-quality nitrogen and sulfur fertilizer, widely used in row crops, oilseeds and as a base for compound NPK blending.
Granular Caprolactam Grade
Ammonium sulfate, commonly known as ammonium sulfate, is an inorganic salt compound with the chemical formula (NH4) 2SO4 and a molecular weight of 132.14. At room temperature, it is a colorless rhombohedral crystal. Industrial products are generally small white or slightly yellow grains, but a few by-products have colors such as slight blue and dark brown.
The relative density is 1.77, the melting point is 280 ℃ (decomposition), and it is soluble in water but insoluble in ethanol and acetone. The aqueous solution is acidic (pH=5.5, 0.1mol/L), and the solubility in water decreases with increasing ammonia content . Ammonium sulfate is prone to moisture absorption and solidifies into blocks after absorbing moisture.
The chemical properties reflect the characteristics of ammonium salts and sulfates. It reacts with alkali to release ammonia gas, which can be decomposed into ammonia gas, nitrogen gas, and sulfur dioxide when heated. It forms barium sulfate precipitate with barium chloride and brown precipitate with alkaline mercuric potassium iodide solution
