A univalent hydrocarbon radical of the ethylene series, CH2:CH; - - called also vinyl. See Vinyl.

A white, crystalline hydrocarbon, regarded as a polymeric variety of ethylene, obtained in heavy oil of wine, the residue left after making ether; -- formerly called also concrete oil of wine.

An oily hydrocarbon regarded as a polymeric variety of ethylene, produced with etherin.

An unsymmetrical, divalent, hydrocarbon radical, C2H4 metameric with ethylene but written thus, CH3.CH to distinguish it from the symmetrical ethylene, CH2.CH2. Its compounds are derived from aldehyde. Formerly called also ethidene.

ick, colorless liquid, C2H4(OH)2, of a sweetish taste, produced artificially from certain ethylene compounds. It is a diacid alcohol, intermediate between ordinary ethyl alcohol and glycerin.

A colorless liquid hydrocarbon, C7H14, of the ethylene series; also, any one of its isomers. Called also heptene.

A colorless, liquid hydrocarbon, C6H12, of the ethylene series, produced artificially, and found as a natural product of distillation of certain coals; also, any one several isomers of hexylene proper. Called also hexene.

ial, organic bases, usually produced as thick viscous liquids by the action of ammonia on ethylene oxide. They have the properties both of alcohol and amines.

said specifically of groups or series which differ by a constant difference; as, ethane, ethylene, an acetylene, or their analogous compounds, form an isologous series.

e, while sarcolactic acid rotates the plane of polarization to the right. The third acid, ethylene lactic acid, accompanies sarcolactic acid in the juice of flesh, and is optically inactive. -- Lactic ferment, an organized ferment (Bacterium lacticum or lactis), which produces lactic fermentation, decomposing the suga…

Pertaining to, or designating, an acid of the ethylene series, metameric with fumaric acid and obtained by heating malic acid.

An unsaturated hydrocarbon, C30H60, of the ethylene series, obtained from beeswax as a white, scaly, crystalline wax; -- called also melissene, and melissylene.

See Methylene.

Any one of a series of metameric, unsaturated hydrocarbons C9H18 of the ethylene series.

Any one of a series of metameric hydrocarbons (C8H16) of the ethylene series. In general they are combustible, colorless liquids.

ing or producing an oil; specifically, designating a colorless gaseous hydrocarbon called ethylene. [Archaic]

Olefiant gas, or ethylene; hence, by extension, any one of the series of unsaturated hydrocarbons of which ethylene is a type. See Ethylene.

A crystalline substance, (C2H4NH)2, formed by action of ammonia on ethylene bromide, by reduction of pyrazine, etc. It is a strong base, and is used as a remedy for gout.

A colorless gaseous hydrocarbon (C3H6) of the ethylene series, having a garlic odor. It occurs in coal gas, and is produced artificially in various ways. Called also propene.
