olefiant gas
Ethylene Eth"yl*ene ([e^]th"[i^]l*[=e]n), n. [From {Ethyl}.] (Chem.) A colorless, gaseous hydrocarbon, {C2H4}, forming an important ingredient of illuminating gas, and also obtained by the action of concentrated sulphuric acid in alcohol. It is an unsaturated compound and combines directly with chlorine and bromine to form oily liquids (Dutch liquid), -- hence called {olefiant gas}. Called also {ethene}, {elayl}, and formerly, {bicarbureted hydrogen}. [1913 Webster]

{Ethylene series} (Chem.), the series of unsaturated hydrocarbons of which ethylene is the type, and represented by the general formula {CnH2n}. [1913 Webster]
