Anhydrous ammonia is a vital chemical compound widely used as a nitrogen source in agriculture and chemical industries. At normal temperature and pressure, it exists as a gas but is stored as a liquid under high pressure, making it an essential raw material for fertilizer production and industrial applications.

Features and Applications

• Rich nitrogen source for agricultural fertilizers
• Used in chemical industries for producing urea and other nitrogen compounds
• Can be injected directly into soil for fertilization
• Soluble in water and suitable for ammonia solutions production

Technical Specifications

• Chemical Formula: NH₃
• Physical Form: Liquid under pressure, gas at ambient conditions
• Purity: ≥ 99%
• Density: 0.740 g/cm³ (liquid at 0°C)
• Boiling Point: -33.3°C

Safety and Precautions

• Highly corrosive and irritates skin, eyes, and respiratory tract
• Must be stored in pressure-resistant containers
• Avoid contact with acids and oxidizing agents
• Protective equipment: resistant gloves, goggles, and mask

Packaging and Storage

• High-pressure cylinders or specialized storage tanks
• Store in cool, well-ventilated areas
• Prevent leaks and contact with heat sources
• Keep away from flammable and acidic materials

Industrial Applications

• Fertilizer production (urea, ammonium nitrate)
• Chemical and petrochemical industries
• Water treatment and industrial cleaning agents
• Industrial refrigeration systems

Anhydrous ammonia was first used in the late 19th century as an industrial fertilizer and in urea production, significantly boosting crop yields in Europe.

Recent studies indicate that controlled use of anhydrous ammonia can improve nitrogen use efficiency in soil and reduce greenhouse gas emissions. Research Source
