CAS Number 74-84-0 corresponds to Ethane, a colorless, odorless, and flammable gas that is a member of the alkane series. It is a major component of natural gas and is widely used in various industries. Here are some key characteristics of ethane:
Chemical Formula: C2H6
Physical State: At standard temperature and pressure (STP), ethane exists as a gas.
Molecular Weight: Approximately 30.07 g/mol.
Boiling Point: -88.6°C (-127.48°F) at 1 atmosphere.
Melting Point: -183.3°C (-297.94°F).
Density: About 1.356 kg/m³ at STP, making it lighter than air.
Vapor Pressure: High, which is why it is typically stored under pressure as a liquid for transportation.
Solubility: Practically insoluble in water but soluble in organic solvents.
Flammability: Highly flammable, with a flammable range of 3.0%-12.4% by volume in air.
Reactivity: Ethane is relatively stable under normal conditions but can react vigorously with oxidizers, halogens, and strong acids.
Uses of Ethane:
Petroleum Industry: Primarily used as a feedstock for the production of ethylene through steam cracking, which is a crucial step in the manufacture of plastics, synthetic rubber, and other chemicals.
Fuel: Can be used as a fuel directly or blended with propane to create liquefied petroleum gas (LPG).
Coolant: Used in low-temperature refrigeration applications due to its low boiling point.
Organic Synthesis: As a starting material or a reactant in the synthesis of various organic compounds.
Safety Considerations:
Flammability and Explosion Risk: Ethane's high flammability requires careful handling, storage, and transportation to prevent ignition.
Asphyxiation Hazard: In a confined space, ethane can displace oxygen and cause asphyxiation.
Environmental Impact: Although it is not considered toxic, its release into the atmosphere contributes to greenhouse gas effects.
If you are looking for a supplier of ethane, it's important to reach out to chemical suppliers, petrochemical companies, or gas distribution firms that specialize in industrial gases. These companies will have the necessary infrastructure to safely handle, store, and transport ethane in accordance with industry standards and regulations. Always ensure the supplier complies with local and international safety and environmental guidelines.
