SECTION 4: MECHANISM OF ACTION
| Property | Description |
|---|---|
| Fertilizer (Nitrogen Source) | Provides plant-available nitrogen; Urease enzyme converts urea to ammonium (NH₄⁺); Nitrification converts ammonium to nitrate (NO₃⁻); Plants absorb both ammonium and nitrate; Promotes vegetative growth, leaf development, and chlorophyll production. |
| Decomposition | Decomposes upon heating: CO(NH₂)₂ + H₂O → CO₂ + 2NH₃; Releases ammonia (NH₃) and carbon dioxide (CO₂); Can volatilize if not incorporated into soil. |
| Hydrolysis | Urease enzyme catalyzes hydrolysis: CO(NH₂)₂ + 2H₂O → (NH₄)₂CO₃; Produces ammonium carbonate; Can cause ammonia volatilization and pH increase. |
| Nitrification | Soil bacteria oxidize ammonium to nitrite (NO₂⁻) and then to nitrate (NO₃⁻); Nitrate is readily absorbed by plants; Nitrification is pH-dependent (optimal at neutral pH). |
| Denitrification | In waterlogged soils, nitrate can be converted to nitrogen gas (N₂) by denitrifying bacteria; Nitrogen loss to the atmosphere; Can be minimized by proper application timing. |
| Endothermic Dissolution | Urea dissolves in water with heat absorption (endothermic); Solution temperature drops as urea dissolves; Cooling effect in solution. |
SECTION 5: PRODUCTION PROCESS
Industrial Production Method (Bosch-Meiser Process):
Process Flow:
Ammonia (NH₃) + Carbon Dioxide (CO₂) → Ammonium Carbamate (NH₂COONH₄) → Urea (CO(NH₂)₂) + Water
Step-by-Step Description:
Step 1: Ammonia and CO₂ Reaction
2NH₃ + CO₂ → NH₂COONH₄ (Ammonium Carbamate)
Step 2: Dehydration to Urea
NH₂COONH₄ → CO(NH₂)₂ + H₂O
Process Details:
-
Raw Materials: Ammonia (NH₃) and carbon dioxide (CO₂) are compressed to high pressure (150-250 bar) and heated to 180-210°C.
-
Reaction: Ammonia and CO₂ react to form ammonium carbamate in the first reaction step.
-
Dehydration: Ammonium carbamate dehydrates to form urea and water (equilibrium reaction).
-
Separation: Urea is separated from the reaction mixture.
-
Purification: Crude urea is purified by evaporation and crystallization.
-
Prilling/Granulation: Urea is formed into prills or granules for agricultural use.
-
Final Product: White granular or prilled urea (46% N).
Important: The reaction is reversible and equilibrium-limited. Unreacted ammonia and CO₂ are recycled.
