When a mixture of four parts of oil of vitriol and one part of strong spirits of wine, or alcohol, is heated in a retort, a gas is gene - rated, which, when washed by water, is found to be a peculiar gase - ous compound of carbon and hydrogene; it has been called olefiant ❋ Humphry Davy, Sir Humphry Davy (1812)
= -- Coal gas contains light carburetted hydrogen or marsh gas, olefiant gas, ammonia, sulphuretted hydrogen, carbonic acid, carbonic oxide, free hydrogen, and nitrogen. ❋ Unknown (N/A)
Carbureted hydrogen, olefiant gas, etc., are constant associates of the petroleum of springs or wells, and this escape of gas and oil has been going on in some localities, without apparent diminution, for two or three thousand years. ❋ Various (N/A)
Assume a natural gas, the analysis of which in percentages by volume is oxygen = 0.40, carbon monoxide = 0.95, carbon dioxide = 0.34, olefiant gas (C_ {2} H_ {4}) = 0.66, ethane (C_ {2} H_ {6}) = 3.55, marsh gas ❋ Unknown (N/A)
For such waves olefiant gas, for example, would vastly transcend it in absorbing power. ❋ Various (N/A)
In 1868 Huggins compared the spectrum of Winnecke's comet with that of a Geissler tube containing olefiant gas, and found exact agreement. ❋ George Forbes (1892)
On comparing its spectrum with that of an olefiant-gas "vacuum tube" rendered luminous by electricity, he found the agreement exact. ❋ Unknown (1874)
Brédikhine, Vogel, and Huggins [1263] were unanimous in pronouncing its spectrum to be that of marsh or olefiant gas. ❋ Unknown (1874)
The atomic group which constitutes the molecule of olefiant gas, produces many thousand times the disturbance caused by the oxygen, it may be because the group is able to lay a vastly more powerful hold upon the aether than single atoms can. ❋ John Tyndall (1856)
It was at one time supposed that terrestrial or artificial light possessed no chemical rays, but this is incorrect -- Mr. Brande discovered that although the concentrated light of the moon, or the light even of olefiant gas, however intense, had no effect on chloride of silver, or on a mixture of chloride and hydrogen, yet the light emitted by electerized charcoal blackens the salt. ❋ Henry Hunt Snelling (1856)
For the heat emitted by lampblack, olefiant gas is a far more powerful absorber than carbonic acid; in fact, for such heat, with one exception, carbonic acid is the most feeble absorber to be found among the compound gases. ❋ John Tyndall (1856)
Moreover, for the radiation from a hydrogen flame olefiant gas possesses twice the absorbent power of carbonic acid, while for the radiation from the carbonic oxide flame, at a common pressure of one inch of mercury, the absorption by carbonic acid is more than twice that of olefiant gas. ❋ John Tyndall (1856)
To it the oscillations of an atom of free oxygen are just as acceptable as those of the atoms in a molecule of olefiant gas; that the vibrating oxygen then stands so far below the olefiant gas in radiant power must be referred not to period, but to some other peculiarity. ❋ John Tyndall (1856)
Thus the olefiant gas, so light and clear and pervious to luminous rays, was proved to be a most potent destroyer of the rays emanating from an obscure source. ❋ John Tyndall (1856)
Of the rays emitted by our heated plate of copper, olefiant gas absorbs ten times the quantity absorbed by carbonic acid. ❋ John Tyndall (1856)
The pile remaining in its position, a sheet of olefiant gas was caused to issue from the same slit as that through which the oxygen had passed. ❋ John Tyndall (1856)
A second holder containing olefiant gas was then connected with the ring-burner. ❋ John Tyndall (1856)
Of the rays emitted by a carbonic oxide flame, carbonic acid absorbs twice as much as olefiant gas. ❋ John Tyndall (1856)
Hence the olefiant gas laboured under a disadvantage. ❋ John Tyndall (1856)
This result was obtained several times, and when larger proportions of olefiant gas were used, the action seemed still more hopeless. ❋ Michael Faraday (1829)
