At standard temperature and pressure, ethane is a colorless, odorless gas. Like many hydrocarbons, ethane is isolated on an industrial scale from natural gas and as a petrochemical by-product of petroleum refining. Its chief use is as … See more Ethane was first synthesised in 1834 by Michael Faraday, applying electrolysis of a potassium acetate solution. He mistook the hydrocarbon product of this reaction for methane and did not investigate it further. During the period … See more Ethane can be viewed as two methyl groups joined, that is, a dimer of methyl groups. In the laboratory, ethane may be conveniently … See more The chief use of ethane is the production of ethylene (ethene) by steam cracking. When diluted with steam and briefly heated to very high … See more • Biogas: carbon-neutral alternative to natural gas • Biorefining • Biodegradable plastic See more 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 … See more After methane, ethane is the second-largest component of natural gas. Natural gas from different gas fields varies in ethane content … See more At room temperature, ethane is an extremely flammable gas.
