A colorless, crystalline, aromatic hydrocarbon, C6H2(CH3)4, off artificial production, with an odor like camphor.

A solid hydrocarbon, C20H42, of the paraffine series, of artificial production, and also probably occurring in petroleum.

A liquid hydrocarbon, C20H38, of the acetylene series, obtained from brown coal.

One of the higher hydrocarbons of the paraffin series, C11H24, found as a constituent of petroleum. [Written also hendecane.]

A gaseous hydrocarbon, C2H6, forming a constituent of ordinary illuminating gas. It is the second member of the paraffin series, and its most important derivatives are common alcohol, aldehyde, ether, and acetic acid. Called also dimethyl.

A trivalent hydrocarbon radical, CH3.C.

Any similar oxide of hydrocarbon radicals; as, amyl ether; valeric ether. Complex ether, Mixed ether (Chem.), an oxide of two different radicals in the same molecule; as, ethyl methyl ether, C2H5.O.CH3. -- Compound ether (Chem.), an ethereal salt or a salt of some hydrocarbon as the base; an ester. -- Ether engine (M…

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.

A monatomic, hydrocarbon radical, C2H5 of the paraffin series, forming the essential radical of ethane, and of common alcohol and ether. Ethyl aldehyde. (Chem.) See Aldehyde.

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…

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.

A colorless, aromatic, liquid hydrocarbon, C10H12O2 resembling the phenols, and hence also called eugenic acid. It is found in the oils of pimento and cloves.

vegetable and animal substances; -- specifically, an oil consisting largely of the higher hydrocarbons of the paraffin series. [Written also eupion.]

a large class of substances obtained by extraction, and consisting largely of nitrogenous hydrocarbons, such as xanthin, hypoxanthin, and creatin extractives from muscle tissue.

ic acid, under Sebacic. -- Fat series, Fatty series (Chem.), the series of the paraffine hydrocarbons and their derivatives; the marsh gas or methane series. -- Natural fats (Chem.), the group of oily substances of natural occurrence, as butter, lard, tallow, etc., as distinguished from certain fatlike substance of a…

A hydrocarbon extracted from gutta-percha, as a yellow, resinous substance; -- called also fluanil.

A white crystalline hydrocarbon C

A colorless, crystalline hydrocarbon, C13H10 having a beautiful violet fluorescence; whence its name. It occurs in the higher boiling products of coal tar, and is obtained artificially.

A volatile hydrocarbon, used as an illuminant, or for charging illuminating gas.
