ABOUT THIS PRODUCT

Anhydrous Ammonia is a versatile and essential chemical compound widely used in various industrial applications. It is a colorless gas with a pungent, suffocating odor. This compound consists of one nitrogen atom bonded to three hydrogen atoms (NH3) and is known for its high nitrogen content, making it a crucial component in the production of fertilizers.

10 KEY CHARACTERISTICS

1. Chemical Formula: NH3 - Anhydrous ammonia consists of one nitrogen atom bonded to three hydrogen atoms.
2. Physical State: Anhydrous ammonia exists as a gas at room temperature and atmospheric pressure. It can be easily compressed into a liquid for storage and transportation.
3. Density: The density of anhydrous ammonia gas is approximately 0.589 times that of air. This means it is lighter than air and tends to rise.
4. Melting and Boiling Points: Anhydrous ammonia has a melting point of -77.7 degrees Celsius 313-834-1660 degrees Fahrenheit) and a boiling point of -33.3 degrees Celsius 313-834-1660 degrees Fahrenheit) under standard atmospheric conditions.
5. Solubility: Anhydrous ammonia is highly soluble in water, forming a strongly alkaline solution. This property makes it useful in various applications, including agriculture as a nitrogen-rich fertilizer.
6. Reactivity: Anhydrous ammonia is a strong base and can react vigorously with acids. It's also reactive with certain metals and metal oxides.
7. Odor: It has a distinctive, sharp, pungent odor that is easily detectable even at low concentrations. This odor serves as a warning of its presence and potential danger.
8. Toxicity: Anhydrous ammonia is toxic when inhaled in high concentrations. Prolonged exposure to lower concentrations can also lead to respiratory and eye irritation.
9. Flammability: Anhydrous ammonia is not flammable under normal conditions. However, it can support combustion in the presence of a suitable ignition source and oxygen.
10. Corrosiveness: Anhydrous ammonia is corrosive to certain metals, especially in the presence of moisture. It can cause stress corrosion cracking and other forms of metal degradation.
