The density of ethane is {eq}1.36kg/m^3 {/eq} at 0 {eq}^circ {/eq}C, under the same conditions air has a density of {eq}1.28kg/m^3 {/eq} . This means that ethane is slightly heavier than air. As a result, it can present a danger of suffocation due to the displacement of air.
How is ethane used in the production of ethylene?
The main use of ethane is as a feedstock chemical for the production of ethylene. Ethylene is produced using a process called steam cracking. This process involves breaking down, or cracking, hydrocarbons into smaller molecules using steam-generated heat. A mixture of ethane and propane are fed into a furnace and cracked to form ethylene and other byproducts. The ethylene is then filtered out from the byproducts.

Why is ethane favored for ethene production?
Ethane is favored for ethene production because the steam cracking of ethane is fairly selective for ethene, while the steam cracking of heavier hydrocarbons yields a product mixture poorer in ethene and richer in heavier alkenes (olefins), such as propene (propylene) and butadiene, and in aromatic hydrocarbons .
How is ethane separated from methane?
Ethane is most efficiently separated from methane by liquefying it at cryogenic temperatures. Various refrigeration strategies exist: the most economical process presently in wide use employs a turboexpander, and can recover more than 90% of the ethane in natural gas. In this process, chilled gas is expanded through a turbine, reducing the temperature to about −100 °C (−148 °F). At this low temperature, gaseous methane can be separated from the liquefied ethane and heavier hydrocarbons by distillation. Further distillation then separates ethane from the propane and heavier hydrocarbons.

Combustion occurs by a complex series of free-radical reactions. Computer simulations of the chemical kinetics of ethane combustion have included hundreds of reactions. An important series of reaction in ethane combustion is the combination of an ethyl radical with oxygen, and the subsequent breakup of the resulting peroxide into ethoxy and hydroxyl radicals.
What is the boiling point of ethane?
At standard temperature and pressure, ethane is a colorless, odorless gas. It has a boiling point of −88.5 °C (−127.3 °F) and melting point of −182.8 °C (−297.0 °F). Solid ethane exists in several modifications. On cooling under normal pressure, the first modification to appear is a plastic crystal, crystallizing in the cubic system. In this form, the positions of the hydrogen atoms are not fixed; the molecules may rotate freely around the long axis. Cooling this ethane below ca. 89.9 K (−183.2 °C; −297.8 °F) changes it to monoclinic metastable ethane II ( space group P 21/n). Ethane is only very sparingly soluble in water.
Names and Etymology
Preparation
History
Isomerism
- Ethane, or ethyne, is an ethyl (ethylene) compound, but ethene and ethane have two different meanings. "Ethane" is used to mean the name of a compound and is a homologue of ethylene. "Ethene" is the name of a hydrocarbon compound, which is often substituted with a carbonyl group. Thus, both names could refer to the same or a related chemical compou...
Physical Chemistry
- The most direct method of manufacturing ethane is to distil and purify crude ethane. It can also be prepared by converting ethane to ethylene and hydrogen by the reaction with hydrogenation and carbon monoxide over an iron catalyst. Ethane is a colourless, nontoxic gas with a peculiar odour. It is a gas at room temperature but becomes a liquid when cooled below -78.5 °C. The va…
What Is ethane?
- The discovery of ethane is associated with the chemist Dmitri Mendeleev, who worked in the 1830s. By looking at the periodic table he realised that the element in the table was missing; it should have a formal oxidation state of −2. However, it was first observed in 1859 by Dmitri Mendeleev. Its melting point of 62 °C (147.2 °F) was first measured in 1862. In the 19thcentury, …
Molecular Structure
- There are four isomers of ethane. The cis-isomer (in which the groups are in the same plane) and the trans-isomer (in which the groups are perpendicular to one another) exist in a ratio of 60:40. The other two, andro- and tele-isomers (in which the groups are at an angle) are never observed. Isomers can be distinguished by measuring the mass of a molecule using a mass spectrometer…
