Oxidative Dehydrogenation Can Be Used As Oxidant
Jan 10, 2018

Nitrobenzene, organic compounds, also known as spot oil, bitter almond oil, colorless or light yellow with bitter almond flavor oily liquid. Hard to dissolve in water, density than water; soluble in ethanol, ether, benzene and oil. In case of fire, high fever will burn, explode. Reacts violently with nitric acid. Nitrobenzene by nitric acid and nitric acid derived from nitric acid. For organic synthesis intermediates and for the production of aniline raw materials. For the production of dyes, spices, explosives and other organic synthesis industry.

A molecule of benzene in which one hydrogen atom is replaced by a nitro group. Colorless or light yellow (containing nitrogen dioxide impurities) oily liquid, like a special smell of almond oil. The relative density of 1.2037 (20/4 ℃). Nitro is a strong passivation base, nitrobenzene to electrophilic substitution reaction occurs under strong conditions, generating meta products; a weak oxidation, can be used as oxidant for oxidative dehydrogenation. Nitrobenzene commonly used nitric acid and sulfuric acid mixed with benzene reaction system. Mainly for the preparation of aniline, benzidine, azobenzene and so on. Nitrobenzene strong toxicity, inhalation of a large number of vapor or skin contamination, can cause acute poisoning, hemoglobin oxidation or complexation, the blood becomes dark brown, and cause headache, nausea, vomiting and so on. Is a colorless or slightly yellow oily bitter almond liquid. (Pure should be colorless, laboratory nitrobenzene due nitric acid dissolved nitric acid generated by the decomposition of color, sodium hydroxide solution can be added after the liquid was removed)

Nitrobenzene is an important organic intermediate. Nitrobenzene is sulfonated with sulfur trioxide to obtain n-nitrobenzenesulfonic acid. Can be used as dye intermediates mild oxidant and anti-salt S. Nitrobenzene with sulfonated sulfonated nitrobenzene sulfonyl chloride, used as dyes, pharmaceutical intermediates. Nitrobenzene by chlorination of nitrochlorobenzene, widely used in the production of dyes, pesticides, available after reduction chloroaniline. For dye orange-based GC, but also medicine, pesticides, optical brighteners, organic pigments and other intermediates. Nitrobenzene re-nitration available between dinitrobenzene, available after reduction of phenylenediamine, used as dye intermediates, epoxy resin curing agent, petroleum additives, cement accelerator, m-dinitrobenzene such as the use of sulfide Partial reduction of sodium yields nitroaniline. For the orange base R dye, azo dyes and organic pigments and other intermediates.
