Ammonium Sulfate, scientifically known as (NH₄)₂SO₄ and bearing the CAS number 7783-20-2, is a vital chemical compound with a wide array of applications, most notably in agriculture and various industrial sectors. Understanding its chemical properties and manufacturing processes is key to appreciating its value and ensuring its effective use. As a premier chemical manufacturer and supplier, NINGBO INNO PHARMCHEM CO.,LTD. offers insights into this important substance and the quality we provide.

The chemical structure of Ammonium Sulfate consists of two ammonium cations (NH₄⁺) and one sulfate anion (SO₄²⁻). It typically appears as white or off-white granules or crystals. Its solubility in water is high, and aqueous solutions are characteristically acidic due to the hydrolysis of the ammonium ion. This acidity is a critical property exploited in soil amendment, as it helps to lower the pH of alkaline soils, thereby improving the availability of essential micronutrients for plant uptake. This makes it a sought-after product for those looking to purchase fertilizers that actively improve soil conditions.

The manufacturing of Ammonium Sulfate predominantly involves two main methods. The most common is the direct synthesis from ammonia (NH₃) and sulfuric acid (H₂SO₄). This reaction is exothermic and straightforward, yielding a high-purity product: 2NH₃ + H₂SO₄ → (NH₄)₂SO₄. This process is widely employed due to the ready availability of raw materials and the efficiency of the reaction, ensuring a consistent supply for chemical companies and end-users alike.

An alternative production route involves the ammonia process, particularly relevant in regions where hydrogen sulfide (H₂S) is a common industrial byproduct. In this method, ammonia reacts with hydrogen sulfide to form ammonium sulfide, which is then oxidized to produce Ammonium Sulfate. While more complex, this process allows for the utilization of waste streams, contributing to a more circular economy in chemical production.
