Ethylene
1. Properties of Ethylene:
- Chemical Formula: C₂H₄
- Molecular Weight: 28.05 g/mol
- Physical State: Colorless gas at room temperature and pressure.
- Boiling Point: -103.7°C (-156.7°F)
- Melting Point: -169°C (-272°F)
- Density: 1.178 kg/m³ at 0°C
2. Reactivity:
Ethylene is highly reactive due to the presence of a double bond between its carbon atoms, making it a key component in chemical reactions such as polymerization, oxidation, and combustion.
3. Applications of Ethylene:
- Polymer Production: Ethylene is a crucial raw material for producing polyethylene (PE), a widely used plastic in packaging, pipes, and films.
- Chemical Synthesis: Used in the production of chemicals like ethylene oxide, alcohols, and acetic acid.
- Agriculture: Ethylene is utilized in agriculture to regulate fruit ripening, plant growth, and flowering.
- Energy and Fuel: Employed as a fuel and feedstock for various combustion and combustion-related processes.
4. Safety and Handling:
Hazards: Highly flammable, can cause asphyxiation in high concentrations.
Protective Measures: Use in well-ventilated areas, avoid prolonged exposure, and store in pressurized containers.
5. Storage:
Ethylene should be stored in specialized, pressurized containers, typically at low temperatures and away from any sources of ignition.
