Use Nitrobenzene is an important organic intermediate thereof. Nitrobenzene was sulfonated with sulfur trioxide to obtain m-nitrobenzene sulfonic acid. It can be used as a dye intermediate, mild oxidant and anti-dye salt s. Nitrobenzene was sulfonated with chlorosulfonic acid to obtain m-nitrobenzenesulfonyl chloride, which was used as intermediate of dye, medicine and so on. Nitrobenzene is chlorinated to M-nitrochlorobenzene, which is widely used in the production of dyes and pesticides. After reduction, M-chloroaniline can be obtained. Used as a dye orange GC, is also a pharmaceutical, pesticide, fluorescent whitening agent, organic pigment intermediates. Nitrobenzene re-nitration can be m-dinitrobenzene, by reduction can be m-phenylenediamine, used as dye intermediates, epoxy resin curing agent, petroleum additives, Cement accelerator, M-dinitrobenzene such as sodium sulfide for part also principle to M-nitroaniline. For the dye orange base R, is an intermediate of azo dyes and organic pigments.

Introduction

Nitrobenzene) is an organic compound that can be a white crystalline solid or a yellow liquid with a special aroma. The following is an introduction to some of the properties, uses, preparation methods and safety information of nitrobenzene:

 

Quality:

Nitrobenzene is insoluble in water but soluble in organic solvents such as alcohols and ethers.

It can be obtained by nitrating benzene, which is produced by reacting benzene with concentrated nitric acid.

Nitrobenzene is a stable compound, but it is also explosive and has a high flammability.

 

Use:

Nitrobenzene is an important chemical raw material and is widely used in organic synthesis.

Nitrobenzene can also be used as an additive in solvents, paints and coatings.

 

Method:

The preparation method of nitrobenzene is mainly obtained by the nitrification reaction of benzene. In the laboratory, benzene can be mixed with concentrated nitric acid and concentrated sulfuric acid, stirred at low temperatures, and then rinsed with cold water to obtain nitrobenzene.

 

Safety Information:

Nitrobenzene is a toxic compound, and exposure to or inhalation of its vapor can cause damage to the body.

It is a flammable and explosive compound and should avoid contact with ignition sources.

Personal protective equipment such as protective gloves and goggles should be worn when handling nitrobenzene, and a well-ventilated operating environment should be maintained.

In the event of a leak or accident, appropriate measures should be taken promptly to clean up and dispose of it. Comply with relevant laws and regulations to properly dispose of the waste generated.
