One of the higher alcohols of the methane series, homologous with ethal, and found in small quantities as an ethereal salt of stearic acid in spermaceti.
A white waxy substance, found in small quantities in spermaceti as an ethereal salt of several fatty acids, and regarded as an alcohol of the methane series.
It consists of a complex mixture of various hydrocarbons, largely of themethane series, but may vary much in appearance, composition, and properties.
We use that heat to turn a chemical called methane into its component parts.
From the direction of the stern came a rising roar as liquid methane dropped into the blast tubes, flaming into pure carbon and hydrogen under the terrible heat of the atomic drive.
As each methane molecule breaks up the carbon atoms are thrown out, forming solid particles of carbon, and it is they really which give the light.
This undoubtedly does collect in many mines, and since it is much the same as the domestic coal-gas (indeed methane forms the bulk of coal-gas) it is not surprising that the explosions were attributed to it.
The explosion ofmethane stirs up the dust, which then explodes.
Some of those carbides yield acetylene when treated with water, some are not attacked, some give liquid products, and some yield methane, or mixtures of methane and hydrogen.
Methane is an exceedingly stable gas, being unaffected by the action of chromic acid, nitric acid, or a mixture of nitric and sulphuric acids.
It is also obtained by the reduction of many methyl compounds with nascent hydrogen; thus methyl iodide dissolved in methyl alcohol readily yields methanewhen acted on by the zinc-copper couple (J.
Methane is a colourless gas of specific gravity 0.
Methane is yielded by aluminium and beryllium carbides, and, mixed with hydrogen, by manganese carbide.
Sprawled across the frozen methane plain a couple of points to starboard Coldfield's lights shimmered through its frost-crusted, barely translucent dome.
Planet Pluto spread across half the tank with its flat stretches of methane frost broken by low, jagged chasms, hillocks and craters.
Adjusted magnification defined the vehicles as personnel carriers, flatbed trailers, dome fissure-fusers, and methane frost scrapers.
All we need trouble about, however, is the first two, Methane and Ethane.
Methane is also given off by petroleum and it is the cause of the explosions in coal mines, being known to the miners as "firedamp.
Adjusting their oxygen masks, Captain Strong and Sergeant Morgan strode down the street through the swirling mist of deadly methane ammonia to begin their search for Tom and Astro.
And, all the while, the deadly methane ammonia gas dropped lower and lower until it was within ten feet of the ground.
The pressure is dropping and yet there is no indication that the force screen, holding back the real methane ammonia atmosphere of Titan, is not functioning properly.
Outside, they walked slowly through the swirling methane ammonia and Tom edged closer to his unit mate.
By shooting these impulses into the air around a certain area, like the settlement at Olympia, we can refract the methane ammonia, push it back if you will, like a solid wall.
The two spacemen clung together blinded by the dense methane ammonia that would kill them in thirty seconds should their oxygen masks fail.
Slowly the satellite of Saturn was dying, and through the methane ammonia atmosphere, the glittering rings of the mother planet shone down on her death struggle.
They had to put on their oxygen masks as the deadly fumes of the methane ammonia atmosphere began to swirl around them.
The air in the room was clear, completely free of the misty whirling methane ammonia of death that swirled around them outside.
He was startled to feel the faint rush of air on his hands and to see the room clear of the dangerous methaneammonia gas.
Captain Strong grabbed the young master sergeant by the arm and stood stock-still in the swirling methane ammonia gas, his eyes searching the misty sky.
The force screens hold back the methane ammonia gas and create a vacuum into which we pump oxygen, right?
He knew that unless the defect in the force fields was corrected soon, the outer-space colony would have to be abandoned to the deadly methane ammonia atmosphere.
As methane is not self-inflammable there remains the difficulty of explaining how it becomes lighted.
Fire damp or methane gas burning inside the wire gauze of the safety-lamp.
You can't see the little cap of methane gas flame burning above the oil flame of the lamp until there's 2 per cent.
Defn: Any one of the three metameric hydrocarbons, C5H12, of the methaneor paraffin series.
Defn: A hydrocarbon, C13H28, of the methane series, which is a probable ingredient both of crude petroleum and of kerosene, and is produced artificially as a light colorless liquid.
Defn: A nitro derivative of methane obtained as a mobile liquid; -- called also nitrocarbol.
Defn: A white waxy substance, found in small quantities in spermaceti as an ethereal salt of several fatty acids, and regarded as an alcohol of the methane series.
Defn: The technical name of methyl alcohol or wood spirit; also, by extension, the class name of any of the series of alcohols of the methane series of which methol proper is the type.
Defn: Any one of a group of metametric hydrocarcons (C8H18) of the methane series.
Defn: One of the higher alcohols of the methane series, homologous with ethal, and found in small quantities as an ethereal salt of stearic acid in spermaceti.
Ammonia andmethane would be blocked, but my suit would have slowly gotten more and more hydrogen in it.
It could insinuate itself into places where neither the methane nor the ammonia could get.
Add to that the fact that hydrogen and methane are both colorless, odorless, and tasteless, and you have the beginnings of an explosive situation.
The seas of Eisberg were liquidmethane containing dissolved ammonia.
The equivalence of the four hydrogen atoms of methanerested on indirect evidence, e.
CH3NO2, each atom in methane being successively replaced by the nitro-group.
Equally well we may derive it from methane by replacing a hydrogen atom by the monovalent group CH2.
In methane and ethane the hydrogen atoms are of equal value, and no matter which one may be substituted by another element or group the same compound will result.
A further generalization was effected by August Kekule, who rejected the hydrochloric acid type as unnecessary, and introduced the methane type and condensed mixed types.
The methane series is the most extensive, all of the compounds up to C{24}H{50} being known.
In 1815 Sir Humphry Davy invented a lamp for the use of miners, to prevent the dreadful mine explosions then common, due to methane mixed with air.
Only two of them, methane and acetylene, will be discussed here.
Thus in the methane group the first four members are gases at ordinary temperatures; those containing from five to sixteen carbon atoms are liquids, the boiling points of which increase with the number of carbon atoms present.
In some series, as the methane series, the higher members are solids.
This can be made by treating methanewith chlorine, as just indicated, although a much easier method consists in treating alcohol or acetone (which see) with bleaching powder.
Methane is a colorless, odorless gas whose density is 0.
Methane is prepared in the laboratory by heating sodium or calcium acetate with soda-lime.
The preparation and properties of methane and acetylene have been discussed in a previous chapter.
Those gases which contain less methane contain all the more hydrogen, viz.
The proportion of formaldehyde to phenol used led Steasny to conclude that the resulting products were diphenyl-methane derivatives which polymerize to form molecules of considerable size.
Similarly nascent methane may reduce iron salts, and the black mud in which these bacteria often occur owes its colour to the FeS formed.
When calcium sulphate is present, the nascent methane induces the formation of calcium carbonate, sulphuretted hydrogen and water.
In depth of medium or "shake" cultures there is an abundant formation of bubbles of gas (methane or carbon dioxide) in the medium.
Hydrogen, carbonic acid, nitrogen, and methane occur, and cause a characteristic effect which is frequently deleterious to the flavour of the milk and its products.
