How will you prepare p-nitroaniline from p-nitroacetanilide?
- 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.
- Gently warm the mixture to dissolve acetanilide completely.
- 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.
What is melting point of p-nitroacetanilide?
