If a doctor could effect no cures in the tropics beyond what these newly-discovered means of healing, arseno-benzol and emetin, make possible, it would still be worth his while to come out here.
Benzine" is a kind of gasoline, but benzene alias benzol has quite another constitution, although it looks and burns the same.
By the use of potassium chloride it was found possible to effect a separation with benzol and water, also with naphtha and water.
Benzol and naphtha were tried, instead of ether, but the results were less satisfactory.
Prizes for the most effective benzol-consuming engine, for benzol carburettors, etc.
I am told that during the war ingenious inventions for the more satisfactory employment of benzol have been adopted.
This was a natural outgrowth of her marvellously developed coal-tar industry, of which benzol is a product.
To turn to substitutes other than food, it will be recalled that Germany very early began to popularise the use of benzol as an alternative to petrol for motor engines.
The wonderful results that have accrued from the benzol theory are patent to all of us.
By replacing the hydrogen atoms corresponding to each carbon atom by other elements or radicals one could arrive at the knowledge of the constitution of a large number of aromatic bodies which now figure as benzol derivatives.
In 1867 he gratified his fellow-chemists by the publication of the first volume of his Chemistry of the Benzol Derivatives.
It has been found possible to gradually range most carbon compounds under two categories, either as marsh-gas or as benzol derivatives, as fatty compounds or as aromatic compounds.
Indeed, Ladenberg has recently succeeded in obtaining benzol as an alteration product from pyridine, in certain reactions.
To decaffeinate coffee, the most common practise is to make the green beans soft by steaming under pressure, and then to apply benzol or chloroform or alcohol to the softened coffee to dissolve and to extract the caffein.
Some of the para-dinitro-benzol is at the same time produced.
The meta-compound is obtained by the action of fuming nitric acid on nitro-benzol at a boiling temperature.
Dinitro-benzol is at present largely employed in the manufacture of explosives, such as roburite, sicherheit, and others.
Excellent accounts of the effects of dinitro-benzol in roburite factories have been published by Dr.
The urinometer must be standardized for the chloroform-benzol mixture.
Mix chloroform and benzol in a urinometer tube so that {147} the specific gravity of the mixture is near the probable specific gravity of the blood.
These explosive bases are derived from benzol and toluol, which in turn are derivatives of coal extracted in the manufacture of coke.
Prior to the war, the big company had made no effort to produce benzoland the other bases for dyes and explosives.
Mansfield proved, by careful experiments, that benzol can be won without difficulty in great quantity from coal-tar oil.
Benzol is a product derived from the gases arising from the destructive distillation of coal in coke ovens.
At the time of which we are writing (beginning of 1915) there was only a comparatively small quantity of benzol produced in the United States.
Ordinarily, it requires from nine to ten months to erect a benzol plant, but before making his proposal to the steel companies Edison had worked out a plan for erecting a practical plant within sixty days, and had laid it out on paper.
Mr. Edison realized that without a continuous and liberal supply of benzol he would be unable to carry out his project of producing carbolic acid in large quantities.
Benzol is also a basic material in making aniline oil.
Decant the water, and wash the nitro-benzol two or three times in a separating funnel with water.
When finished, pour contents of beaker into about a litre of cold water; the nitro-benzol will sink to the bottom.

The floor should be inclined to a drain, to save any nitro-benzol spilt.
A large quantity of acid fumes come off, and some of the nitro- and di-nitro-benzol produced comes off at the high temperature which is attained, and a good condensing apparatus of stoneware must be used to prevent loss.
Other natural results should be the development of substitutes, such as alcohol or benzol for gasoline; the larger recovery of oil from oil shales; and the general speeding up of conservational measures of various kinds.
To make enough benzol (a by-product of coke) to replace gasoline would necessitate the manufacture of many times the amount of coke now required by the world's industries.
The heavier tars contain less benzol than the lighter tars, and more "fixed carbon," which remains behind when the tars are exhausted of benzol and is a decidedly objectionable constituent.
After this the crude benzol is thoroughly washed with water and dilute caustic soda solution, until its reaction is neutral.
