d1nanthic \[d1]*nan"thic\, a. [Gr. [?] the first shoot of the vine, the vine blossom, the vine; [?] the vine + [?] bloom, [?] flower.] (Chem.) Having, or imparting, the odor characteristic of the bouquet of wine; specifically used, formerly, to designate an acid whose ethereal salts were supposed to occasion the peculiar bouquet, or aroma, of old wine. Cf. {[d1]nanthylic}. {[d1]nanthic acid}, an acid obtained from [oe]nanthic ether by the action of alkalies. {[d1]nanthic ether}, an ethereal substance (not to be confused with the bouquet, or aroma, of wine) found in wine lees, and consisting of a complex mixture of the ethereal salts of several of the higher acids of the acetic acid series. It has an ethereal odor, and it used in flavoring artificial wines and liquors. Called also {oil of wine}. See {Essential oil}, under {Essential}. | |

See under {Laughing}. {Marsh gas} (Chem.), a light, combustible, gaseous hydrocarbon, {CH4}, produced artificially by the dry distillation of many organic substances, and occurring as a natural product of decomposition in stagnant pools, whence its name. It is an abundant ingredient of ordinary illuminating gas, and is the first member of the paraffin series. Called also {methane}, and in coal mines, {fire damp}. {Natural gas}, gas obtained from wells, etc., in Pennsylvania, Ohio, and elsewhere, and largely used for fuel and illuminating purposes. It is chiefly derived from the Coal Measures. {Olefiant gas} (Chem.). See {Ethylene}. {Water gas} (Chem.), a kind of gas made by forcing steam over glowing coals, whereby there results a mixture of hydrogen and carbon monoxide. This gives a gas of intense heating power, but destitute of light-giving properties, and which is charged by passing through some volatile hydrocarbon, as gasoline. | |
