∙ 12y ago
A nitration mixture is a combination of nitric acid and sulfuric acid used in chemical reactions to introduce a nitro group (NO2) onto an organic molecule. The sulfuric acid serves as a catalyst and dehydrating agent, while the nitric acid supplies the nitro group for the reaction. It is commonly used in the synthesis of nitroaromatic compounds.

What is the introduction of preparation of m-dinitrobenzene nitration of nitrobenzene?
The preparation of m-dinitrobenzene through the nitration of nitrobenzene involves reacting nitrobenzene with a nitration mixture containing concentrated sulfuric acid and nitric acid. The nitro group on the nitrobenzene is replaced by a nitronium ion generated from the nitration mixture, leading to the formation of m-dinitrobenzene. The reaction is typically carried out under controlled conditions to regulate the regioselectivity of the nitration process.
How much quantity nitric acid and sulfuric acid in nitration mixture?
The typical nitration mixture consists of concentrated sulfuric acid and nitric acid in a specific ratio, such as a 3:1 mixture of sulfuric acid to nitric acid to allow for nitration reactions to occur effectively. The exact quantities may vary depending on the specific reaction being carried out and the desired outcome. It is important to consult a protocol or experienced chemist for the precise amounts needed for a particular nitration reaction.
What is nitric and sulfuric acid also known as?
Nitric and sulfuric acid together are commonly known as nitration mixture. This mixture is highly corrosive and used in various organic synthesis reactions involving nitration.
Where will be NO2 plus group attached in Nitration of chlorobenzene?
In the nitration of chlorobenzene, the NO2 group will typically replace one of the hydrogen atoms on the benzene ring, resulting in the formation of nitrochlorobenzene. The nitration reaction occurs at the ortho or para position to the chlorine atom due to the directing effect of the chlorine substituent.
Why is -NH2 group of aniline protected before nitration?
The -NH2 group of aniline is protected before nitration to prevent unwanted side reactions with the nitration reagents. Adding a protecting group to the -NH2 group helps to direct the nitration reaction to the desired position on the aromatic ring, improving selectivity and yield of the desired product.

Why after a nitration reaction?
For example nitrobenzene is obtained by nitration of benzene.
Why nitration reaction is not used for synthesis of p-nitroaniline?
due to we do this reaction in acidic condition here the formation of anilinium ion takesplace which is deactivating group then if we add nitration mixture substitution takes place at meta position means we don't get 4-nitroaniline
Nitration of aniline with nitrating mixture gives m-nitro-aniline?
In the nitration of aniline with a nitrating mixture, the electrophilic attack of the nitronium ion occurs at the ortho and para positions due to the activating effect of the amino group. The major product obtained is m-nitroaniline due to steric hindrance that prevents substitution at the ortho position.
Where will be NO2 plus group attached in Nitration of chlorobenzene?
In the nitration of chlorobenzene, the NO2 group will typically replace one of the hydrogen atoms on the benzene ring, resulting in the formation of nitrochlorobenzene. The nitration reaction occurs at the ortho or para position to the chlorine atom due to the directing effect of the chlorine substituent.
Why nitration of nitrobenzene is difficult than nitration of benzene?
Nitration of nitrobenzene is more difficult because the nitro group is an electron-withdrawing group, making the nitrobenzene less reactive towards electrophilic aromatic substitution reactions. In contrast, benzene is more reactive because it does not have any electron-withdrawing groups attached to it.
Why is -NH2 group of aniline protected before nitration?
The -NH2 group of aniline is protected before nitration to prevent unwanted side reactions with the nitration reagents. Adding a protecting group to the -NH2 group helps to direct the nitration reaction to the desired position on the aromatic ring, improving selectivity and yield of the desired product.
How do you do nitration of salicylicacid?
Well a standard nitration with mixed acids at elevated temperatures. One could just follow the nitration of its brother, acetylsalicylicacid (ASA) as in the same way TriNitroPhenol (TNP) is made.
What has the author Howard William Post written?
Howard William Post has written: 'The nitration of substituted anilines ..' -- subject(s): Aniline, Nitration 'The chemistry of the aliphatic orthoesters' -- subject(s): Esters
What chemical change starts with letter N?
You think probable to nitration.
Reactant used to synthesize nitrobenzene?
Nitrobenzene is typically synthesized by nitration of benzene using a mixture of concentrated nitric acid and sulfuric acid as the nitrating agents. The reaction involves the substitution of a hydrogen atom on the benzene ring with a nitro group, resulting in the formation of nitrobenzene.
What is the role of concentrated sulfuric acid in the nitration of methyl benzoate?
Concentrated sulfuric acid serves as a catalyst in the nitration of methyl benzoate. It helps in protonating the nitric acid to form a stronger electrophile, the nitronium ion, which then attacks the aromatic ring of methyl benzoate to facilitate the nitration reaction. Additionally, it helps in removing water produced during the reaction to drive the equilibrium towards the product formation.
