WebSep 1, 2010 · Methane and ethane (the major components of natural gas) are simple asphyxiants and the most toxic components (propane and butane) in the mixture are present in small amounts. Therefore, the rationale for the TLV for light hydrocarbons and natural gas needs to be explored on a scientific basis. Methods: WebFeb 17, 2024 · ethane: [noun] a colorless odorless gaseous alkane C2H6 found in natural gas and used as a fuel.
Ethane is an organic chemical compound with chemical formula C 2H 6. 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 synthesised by Kolbe electrolysis. … 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 temperatures (900 °C or more), heavy hydrocarbons break down into lighter hydrocarbons, and saturated hydrocarbons 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 … 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. When mixed with air at 3.0%–12.5% by volume, it forms an explosive mixture. Some additional precautions are necessary where ethane is stored as a cryogenic liquid. … See more
