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

A colorless liquid hydrocarbon of the octylene series, occurring in Caucasian petroleum.

A hypothetical hydrocarbon radical regarded as an essential residue of octane, and as entering into its derivatives; as, octyl alcohol.

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

A hydrocarbon radical formerly supposed to exist in oenanthic acid, now known to be identical with heptyl.

A colorless liquid hydrocarbon, having a garlic odor; heptine.

Forming 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 termination indicating that the hydrocarbon to the name of which it is affixed belongs to the fourth series of hydrocarbons, or the third series of unsaturated hydrocarbonsl as, nonone.

n which the two methyl groups are in the ortho position; a colorless, liquid, combustible hydrocarbon resembling benzene.

A hydrocarbon radical (C2O2) regarded as a residue of oxalic acid and occurring in derivatives of it.

garded as a definite compound, but is now known to be a complex mixture of several higher hydrocarbons of the methane or marsh-gas series; hence, by extension, any substance, whether solid, liquid, or gaseous, of the same chemical series; thus coal gas and kerosene consist largely of paraffins.

A hydrocarbon of the aromatic series obtained as a colorless liquid by the distillation of camphor with zinc chloride. It is one of the three metamers of xylene. Cf. Metamer, and Xylene.

A hydrocarbon of the paraffin series, (C15H32) found in petroleum, tar oil, etc., and obtained as a colorless liquid; -- so called from the fifteen carbon atoms in the molecule.

A hypothetical hydrocarbon, C5H10, metameric with the amylenes, and the nucleus of a large number of derivatives; -- so named because regarded as composed of five methylene residues. Cf. Trimethylene, and Tetramethylene.

Any one of the three metameric hydrocarbons, C5H12, of the methane or paraffin series. They are colorless, volatile liquids, two of which occur in petroleum. So called because of the five carbon atoms in the molecule.

An unsaturated hydrocarbon, C5H8, of the acetylene series. Same as Valerylene.

r forced by pressure of the gas attending it. It consists of a complex mixture of various hydrocarbons, largely of the methane series, but may vary much in appearance, composition, and properties. It is refined by distillation, and the products include kerosene, benzine, gasoline, paraffin, etc. Petroleum spirit, a vol…

A complex hydrocarbon, C14H10, found in coal tar, and obtained as a white crystalline substance with a bluish fluorescence.

A nitrogenous hydrocarbon base, C13H9N, analogous to phenanthrene and quinoline.
