It is a colorless, oily liquid, originally obtained from indigo by distillation, but now largely manufactured from coal tar or nitrobenzene as a base from which many brilliant dyes are made. Webster's Unabridged Dictionary 2012-03-24T02:00:23.513Z

One of the simplest and longest-known members of this group is nitrobenzene, C6H5NO2, which is employed to some extent as an explosive, being one ingredient in rack-a-rock and other blasting compositions.

Closely related thereto is a bluish-grey called “nigrosine,” obtained by heating nitrobenzene with aniline, as well as a certain bluish by-product obtained during the formation of magenta, and known as “violaniline.” Coal and What We Get from It

They are mostly distinguished by special trade names, and are mainly of two classes—those containing ammonium nitrate and nitrobenzene or nitronaphthalene, and those containing nitroglycerin and nitrocellulose, which are essentially weak dynamites. Encyclopaedia Britannica, 11th Edition, Volume 6, Slice 5 "Clervaux" to "Cockade"

Several of these, notably pyridine, phenol and nitrobenzene, cause considerable swelling and gelatinisation of the fibres, but without solution. Researches on Cellulose 1895-1900

A strong action sets in, and on adding water, the nitrobenzene settles down as a heavy oil, and the acid water can be decanted off. The Chemistry of Hat Manufacturing Lectures Delivered Before the Hat Manufacturers' Association

Aniline is manufactured by reducing nitrobenzene with iron and hydrochloric acid and steam-distilling the product. Encyclopaedia Britannica, 11th Edition, Volume 2, Part 1, Slice 1

This important discovery was made in 1880 by the Dutch chemist Skraup, who found that by heating aniline with sulphuric acid and glycerin in the presence of nitrobenzene, quinoline is produced. Coal and What We Get from It

Here they arrange themselves into two layers, the top of which consists of the nitrobenzene which has been produced, together with some benzene which is still unacted upon. The Story of a Piece of Coal What It Is, Whence It Comes, and Whither It Goes

The nitrobenzoate is insoluble in ether alcohol, but is soluble in acetone, acetic acid, and nitrobenzene. Researches on Cellulose 1895-1900

It would probably be more legitimate to base the calculation on the amounts of aniline taken and of nitrobenzene not recovered, since undoubtedly the latter is reduced to aniline during the course of the reaction. Organic Syntheses

Potassium permanganate in neutral solution oxidizes it to nitrobenzene, in alkaline solution to azobenzene, ammonia and oxalic acid, in acid solution to aniline black. Encyclopaedia Britannica, 11th Edition, Volume 2, Part 1, Slice 1

The nitrobenzene acts only as an oxidizing agent; the amido-group of the aniline is converted into a group containing carbon, hydrogen, and nitrogen, i.e. the pyridine group. Coal and What We Get from It

From the nitrobenzene thus obtained, the aniline which is now used so extensively is prepared. The Story of a Piece of Coal What It Is, Whence It Comes, and Whither It Goes

Molecular weight of cellulose and oxycellulose.—The author endeavours to arrive at numbers expressing these relations by converting the substances into acetates by Schutzenberger's method, and observing the boiling-points of their solution in nitrobenzene. Researches on Cellulose 1895-1900

With the use of nitrobenzene, the reaction, according to the original method, takes place with extreme violence. Organic Syntheses

The purity of the product depends upon the quality of the benzene from which the nitrobenzene was prepared. Encyclopaedia Britannica, 11th Edition, Volume 2, Part 1, Slice 1

That aniline could be obtained by the reduction of nitrobenzene was shown by Zinin in 1842, who used sulphide of ammonium for reducing the nitrobenzene, and named the resulting base “benzidam.” Coal and What We Get from It

In practice a given quantity of benzene will yield about 150 per cent of nitrobenzene. The Story of a Piece of Coal What It Is, Whence It Comes, and Whither It Goes

As stated it is soluble in certain of the ordinary solvents of the cellulose esters, e.g. chloroform, acetic acid, nitrobenzene, pyridine, and phenol. Researches on Cellulose 1895-1900

The production of aniline from benzene by acting upon this hydrocarbon with nitric acid, and then reducing the nitrobenzene, has already been referred to. Coal and What We Get from It

The residue of nitric acid which replaces hydrogen in benzene is the nitro-group, and the compound is nitrobenzene. Coal and What We Get from It

A mere trace of aniline is present in the tar ready formed; from the time this base was wanted in large quantities it had to be made by nitrating benzene, and then reducing the nitrobenzene. Coal and What We Get from It

There are various methods of reducing nitrobenzene for aniline, the object being to replace the oxygen of the former by an equivalent number of atoms of hydrogen. The Story of a Piece of Coal What It Is, Whence It Comes, and Whither It Goes

Equal volumes of nitrobenzene and acetic acid, together with a quantity of iron-filings rather in excess of the weight of the nitrobenzene, are placed in a capacious retort. The Story of a Piece of Coal What It Is, Whence It Comes, and Whither It Goes
