(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.
