Product Description
1. Definition
Ammonium Sulfate, with the chemical formula (NH4)2SO4, is a white crystalline inorganic salt. It is highly soluble in water and is widely used as a nitrogen- and sulfur-based fertilizer. The compound contains 21% nitrogen and 24% sulfur by weight, both essential nutrients for plant development. It is non-flammable, stable under normal conditions, and widely recognized for its cost-effective nutrient supply in agriculture.
2. Physical and Chemical Properties
* Appearance: White or colorless crystals or granules
* Molecular Weight: 132.14 g/mol
* Solubility in Water: Approximately 76 g/100 mL at 25°C
* Melting Point: Decomposes at 280°C without boiling
* pH (1% solution): Approximately 5.5-6.5
* Density: Around 1.77 g/cm3
* Odor: Odorless
* (NH4)2SO4 is non-volatile and does not combust, making it a safe and stable compound for both storage and application.
3. Production Methods
* Direct Neutralization:
The most common industrial method involves reacting NH3 with sulfuric acid (H2SO4):
2NH3 + H2SO4 → (NH4)2SO4
This exothermic process is efficient and scalable.
* By-product Recovery:
It is also produced as a by-product during the manufacturing of materials like caprolactam and Methyl-methacrylate. These processes yield (NH4)2SO4 during the neutralization of waste streams containing NH3 and sulfate.
* Absorption Methods:
NH3 gas can be absorbed in sulfuric acid or sulfate-containing liquids, forming (NH4)2SO4 upon crystallization. This is common in emission control systems of certain chemical plants.
4. Storage Conditions
* Dry and Cool: (NH4)2SO4 should be stored in a dry, well-ventilated place to prevent caking or clumping due to moisture absorption.
* Non-corrosive Containers: Use plastic-lined or corrosion-resistant containers or bags.
* Avoid Mixing: It should not be stored with alkaline substances or oxidizers to prevent undesired chemical reactions.
* Shelf Life: Indefinite when stored properly under dry conditions.
5. Substitutes and Competing Products
* Urea: A nitrogen-rich fertilizer with 46% nitrogen content, but it lacks sulfur.
* Ammonium-nitrate: Another nitrogen fertilizer, offering quick nitrogen release but is often regulated due to its explosive nature.
* Calcium Ammonium-Nitrate: A less volatile alternative offering both calcium and nitrogen.
Compared to these, (NH4)2SO4 is valued for providing both nitrogen and sulfur, especially in sulfur-deficient soils.
6. Market Information
* Major Producers: China, the United States, and members of the European Union are key producers.
* Consumption Patterns: Most consumption is in agricultural regions with large-scale crop production, especially in Asia and South America.
* Market Drivers: Demand for nitrogen-sulfur balanced fertilizers, growth in industrial-scale farming, and global food demand.
* Price Influencers: Raw material prices (especially NH3), energy costs, and agricultural seasons.
* HS Code: Typically classified under 310221 for international trade.
7. Downstream Value Chain
* Fertilizer Blending: Often mixed into compound or NPK fertilizers.
* Agrochemical Industry: Used as a carrier in some formulations.
* Food Processing: Approved in limited quantities as a food additive and dough enhancer.
* Water Treatment: Employed in water purification systems to improve clarity and mineral balance.
* Industrial Manufacturing: Serves as a processing aid in dyeing, leather tanning, and fire-retardant formulations.
