Preparation equation of nitrobenzene

Nitrobenzene preparation equation is as follows:

Nitrobenzene preparation equation: C6H6 + HNO3 (concentrated) → C6H5NO2 + H2O. nitrobenzene, organic compounds, also known as mipan oil, bitter almond oil, colorless or yellowish oily liquid with a bitter almond flavor. Difficult to dissolve in water, density greater than water; soluble in ethanol, ether, benzene and oil. Burns and explodes when exposed to open flame and high heat. Reacts violently with nitric acid.

Organic compounds in a narrow sense are mainly composed of carbon and hydrogen elements, must be compounds containing carbon, but does not include carbon oxides and sulfides, carbonic acid, carbonates, cyanide, sulfur cyanide, cyanate, carbide, carbonylborane, carbonyl metal, metal-organic ligand complexes without M-C bonds, some metal-organic compounds (M-C bond-containing substances), etc., which are mainly studied in the Carbon-containing substances studied in inorganic chemistry.

Knowledge Expansion

Nitrobenzene, organic compounds, also known as mipan oil, bitter almond oil, colorless or slightly yellow with a bitter almond flavor oily liquid. Difficult to dissolve in water, density than water; soluble in ethanol, ether, benzene and oil. Burns and explodes when exposed to open flame and high heat. Reacts violently with nitric acid. Nitrobenzene is obtained by nitrifying benzene with nitric acid and sulfuric acid. Used as intermediate of organic synthesis and raw material of aniline production. Used in the production of dyes, spices, explosives and other organic synthesis industry.

Use

Nitro is a strong passivation, nitrobenzene must be in the stronger conditions before the electrophilic substitution reaction to generate meso products; weak oxidation, can be used as oxidizing dehydrogenation of oxidants. Nitrobenzene is often produced by reacting benzene with a mixture of nitric acid and sulfuric acid. Nitrobenzene is an important organic intermediate. Nitrobenzene is sulfonated with sulfur trioxide to obtain m-nitrobenzenesulfonic acid.

It can be used as dye intermediate, mild oxidant and anti-dyeing salt S. Nitrobenzene is sulfonated with chlorosulfonic acid to obtain m-nitrobenzenesulfonyl chloride, which is used as intermediate for dyes, medicine and so on. Nitrobenzene is chlorinated to m-nitrochlorobenzene, which is widely used in the production of dyestuffs and pesticides, and m-chloroaniline can be obtained after reduction.

Used as orange GC for dyestuffs, it is also the intermediate of medicine, pesticide, fluorescent whitening agent, organic pigment and so on. Nitrobenzene and then nitrification can be obtained m-dinitrobenzene, the reduction can be obtained m-phenylenediamine, used as dye intermediates, epoxy resin curing agent, petroleum additives, cement coagulant, m-dinitrobenzene, such as the use of sodium sulfide for part of the reduction of the principle obtained m-nitroaniline. It is an intermediate of azo dyes and organic pigments, etc. It is the orange base R of dyes.
