What is the use of p-nitroacetanilide?
It is used in pharmaceuticals in preparation of paracetamol and phenacetin. Used in pesticides and rubber chemicals also used as an intermediate for dyes.
Why glacial acetic acid is used in the preparation of P Nitroacetanilide?
Glacial acetic acid is used because it is an excellent polar protic solvent capable of dissolving acetanilide. For the process, acetanilide is first dissolved in the solvent, glacial acetic acid, by warming. It’s just a solvent to dissolve anisole (both are polar).

What is the Colour of P Nitroacetanilide?
Nitration of acetanilide proceeds smoothly to give p- nitroacetanilide. When purified well, the product will have light yellow color & it has a melting point close to 214-216 oC.
Why glacial acetic acid is used in preparation of P Nitroacetanilide?
Why glacial acetic acid is used in preparation of p-nitroacetanilide?
What is the Colour of minor product formed in the preparation of p-nitroacetanilide?
The crystals of the p-nitroacetanilide are colourless.
How do you recrystallize p-nitroacetanilide?
In a beaker, pour the mixture into 100 grams of crushed ice and stir well. By doing so, large crystals of p-nitro acetanilide are obtained and then filter those crystals via filter paper. The separated p-nitro acetanilide is washed with cold water to remove excess acid. It is then crystallized from ethyl alcohol.
Is P-Bromoacetanilide soluble?
Moderately soluble in alcohol. Insoluble in water.
What is Bromoacetanilide used for?
Description. 4′-Bromoacetanilide is used as an internal standard for phenylurea and the respective metabolic products in oysters. It has also been used as a reagent in the production of a new ligand to form a coordination compex between gadolinium(III) and T=titanium(IV) oxide.
How do you make p-nitroacetanilide?

What is the Colour of p-nitroacetanilide?
How can you prepare p-nitroacetanilide from aniline?
The organic compound p-nitro acetanilide can be prepared from the acetanilide through nitration. When acetanilide is treated with the nitrating mixture, that is, a mixture of sulphuric acid and nitric acid, it forms p-nitro acetanilide.
Why glacial acetic acid is used in the preparation of p-nitroacetanilide?
