How will you prepare p-nitroaniline from p-nitroacetanilide?

How will you prepare p-nitroaniline from p-nitroacetanilide?


  1. Take 3gm of finely powdered acetanilide in a clean beaker and dissolve it by adding glacial acetic acid by stirring the content carefully at room temperature.
  2. Gently warm the mixture to dissolve acetanilide completely.
  3. Cool the solution and add concentrated sulphuric acid slowly with constant stirring.

How is aniline p-nitroaniline prepared?

Dissolve 4.0 mL of aniline in 10 mL of acetic acid in a 100 mL round bottom flask. To this solution, add 5 mL of acetic anhydride and mix well by swirling. CAUTION: the reaction is exothermic and the flask becomes warm.

How is p-nitroacetanilide prepared from Acetanilide?

Preparation of para nitro acetanilide from acetanilide 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.

How do you synthesize p-nitroaniline?

p-Nitroaniline is toxic, avoid contact with skin, eyes and clothing and handle with care. Charge a 25 mL round bottom flask with a solution of concentrated sulfuric acid (4 mL) and water (3 mL). + Add p-nitroacetanilide (0.7 g) and heat the reaction mixture gently under reflux for 20 min.

How do you separate p-nitroacetanilide?

To separate p-nitroacetanilide from this mixture, the reaction mixture is recrystallised in ethanol, so that the more readily soluble o-nitroacetanilide dissolves in ethanol and pure p-nitroacetanilide separates out.
