Product Description
1. Definition
Ammonium sulfate, with the chemical formula (NH4)2SO4, is an inorganic salt formed by the reaction between sulfuric acid (H2SO4) and NH3. It is a white, crystalline solid composed of ammonium cations and sulfate anions, known for its stability and solubility in water. This compound is produced through a neutralization process, where the acidic properties of H2SO4 react with the basic nature of NH3 to create a stable ionic structure.
2. Physical and Chemical Properties
Physical Properties: Ammonium sulfate appears as odorless, white crystals with a density of approximately 1.77 g/cm³. It has a high solubility in water, with around 70 grams dissolving in 100 grams of water at 0°C, and this solubility increases with temperature. The compound decomposes at around 230 - 280°C instead of melting. Its crystals typically form in an orthorhombic structure, which can be observed under a microscope.
Chemical Properties: Under normal conditions, ammonium sulfate is stable. However, it can react with strong bases, though specific details of such reactions are omitted here. In acidic environments, it remains relatively inert. It can participate in metathesis reactions with other soluble salts, potentially forming insoluble products depending on the reactants. For example, it may react with certain metal salts to produce metal sulfates under suitable reaction conditions.
3. Production Methods
The main production method of ammonium sulfate involves the reaction between H2SO4 and NH3. In a controlled chemical reactor, these two substances are mixed in the appropriate ratios. As the reaction proceeds, ammonium sulfate crystals form and are then separated from the reaction mixture through processes such as evaporation and crystallization. Another approach is to utilize by-products from other industrial processes that contain ammonium and sulfate components. These by-products are purified through filtration, washing, and drying steps to obtain high-purity ammonium sulfate. Recycling of related chemical by-products is often integrated into the production process to enhance sustainability and reduce costs.
4. Storage Methods
Ammonium sulfate should be stored in a cool, dry place, protected from direct sunlight and moisture. Exposure to humidity can cause the crystals to absorb water, leading to caking and degradation of product quality. It is advisable to use airtight containers, such as sealed plastic bags or metal drums, to maintain its dryness. Additionally, it should be stored away from strong oxidizing agents and other incompatible chemicals to prevent potential hazardous reactions. Regular inspection of storage areas helps ensure the compound remains in good condition and retains its usability for various applications.
5. Substitutes and Competitive Products
Common substitutes for ammonium sulfate include urea and calcium ammonium-nitrate. Urea, a nitrogen-rich compound, is widely used as a fertilizer due to its high nitrogen content and relatively low cost in some regions. Calcium ammonium- nitrate offers the combined benefits of nitrogen and calcium, making it suitable for soils lacking both nutrients. Compared to ammonium sulfate, these products may have different nutrient release rates and soil - interaction characteristics, influencing their competitiveness in the market based on specific agricultural and industrial requirements.
6. Market Information
The global market for ammonium sulfate is driven by demand from the agricultural sector, which accounts for the majority of its consumption. Fluctuations in the price of raw materials like H2SO4 and NH3, as well as changes in agricultural policies and crop prices, significantly impact the market. Regions with large agricultural activities, such as Asia and North America, are major consumers. Additionally, emerging industrial applications contribute to the growth of the market, although agriculture remains the dominant factor influencing supply and demand dynamics.
7. Downstream Industries
The downstream industries of ammonium sulfate are mainly agriculture, textiles, leather, and mining. In agriculture, it is used as a fertilizer to enhance crop growth. In the textile industry, it functions as a sizing agent, improving the quality and texture of fabrics. In the leather industry, it helps adjust the pH of tanning solutions, facilitating the tanning process. In mining, ammonium sulfate is applied in flotation processes to separate valuable minerals from ores by modifying the surface properties of the minerals.
