Ethane (/ËÉÎ¸eÉªn/ or /ËiËÎ¸eÉªn/) is an organic chemical compound with chemical formula C 2 H 6. At standard temperature and pressure, ethane is a colorless, odorless gas.Ethane is isolated on an industrial scale from natural gas, and as a byproduct of petroleum refining.he name ethane is derived from the IUPAC nomenclature of organic chemistry. Eth- refers to the presence of 2 carbon atoms, and -ane refers to the presence of a single bond between them.
Sulfur Hexafluoride (SF6)Gas Handling. Sulfur hexafluoride (SF6) in its pure state is inert, nontoxic, odorless, nonflammable and colorless. Ithas excellent arc quenching properties and exhibits exceptional thermal stability. SF6 has exceptionallygood insulating properties and at atmospheric pressure has 2.5 times the dielectric strength of air. SF6 gas at 289.6 KPa (42 psig) has the same dielectric strength as transformer oil. Sulfur hexafluoride remains a gas without liquefying down to -34.4Â°C (-30Â°F) at the gas pressurenormally used in the puffer type breaker. The density of SF6 is about five times that of air (molecularweight equal to 146).
