Ethane (C2H6) is a colorless and odorless gas that is slightly heavier than air. It occurs as a constituent of natural gas, which is the main raw material for its production. It forms an explosive and flammable mixture with air at low concentrations. It is used in the petrochemical industry as a feedstock for the production of ethylene and vinyl chloride.
Some of its physical characteristics are:
|Molecular weight: 30.07||Critical temperature: 305.33 K|
|Melting point: 89.88 K||Critical pressure: 4.872 MPa|
|Normal boiling point: 184.52||Critical density: 206.6 kg/m3|
|Normal vapor density: 1.355 kg/m3||(@ 273.15K; 1.0135MPa)|
