ethane
Ethane is a colourless, odourless organic chemical compound with the formula C2H6[1]. It is a saturated hydrocarbon found in a gaseous state and is the second simplest alkane, following methane. Ethane contains 2 carbon atoms and 6 hydrogen atoms[1]. It is prepared by laboratory methods, such as the reduction of ethyl iodide using zinc + copper couple in alcohol or by the Wurtz reaction[1]. Ethane is a significant component of natural gas and is widely used in many homes[1][3].
Physical Properties
Ethane has a density of 1.36 kg/m³, a molecular weight/molar mass of 30.07 g/mol, a boiling point of -89 °C, and a melting point of -182.8 °C[1]. It is an odourless, colourless gas that is soluble in water[1].
Uses
Ethane has a range of applications, including:
- Used in the petrochemical industry as a fraction of that produced in natural gas liquids plants alone[1].
- Used in the preparation of ethanol, acetaldehyde, and acetic acid, which find use in paints, varnishes, adhesives, and plastics[1].
- Used as the most specific volatile marker for the investigation of lipid peroxidation[1].
- Used to make ethylene, which is used in the manufacture of goods such as plastic, automotive antifreeze, and detergent[1][3].
Production and Trade
In 2023, U.S. ethane production, consumption, and exports set new record highs, driven by continued growth in ethane consumption in the global petrochemical sector and rising ethane recovery associated with natural gas production[2]. U.S. ethane production rose 9% to average 2.6 million barrels per day (b/d) in 2023, with the Texas Inland and New Mexico refining districts accounting for 61% of all U.S. ethane production[2]. Domestic ethane consumption rose 5% in 2023 to 2.1 million b/d, with the petrochemical industry being the primary consumer[2]. U.S. ethane exports averaged a record 471,000 b/d during 2023, driven by growth in global petrochemical sector demand and rising tanker capacity[2].
Safety and Handling
Ethane is extremely flammable and gas/air mixtures are explosive[5]. It requires special handling and safety precautions to prevent fires and explosions, including the use of closed systems, ventilation, explosion-proof electrical equipment, and prevention of electrostatic charges[5]. Inhalation of ethane can cause suffocation, and contact with liquid ethane can cause frostbite[5].
