How do you synthesize acetanilide?

Acetanilide is prepared from aniline when it reacts with acetic anhydride/glacial acetic acid in the presence of zinc dust. A mixture of aniline, glacial acetic acid, acetic anhydride and zinc dust is refluxed under anhydrous condition and then poured the mixture into ice cold water to get acetic anhydride precipitate.

What is the limiting reagent in the synthesis of acetanilide?

There is enough acetic anhydride to produce 0.0467 mol acetanilide, but only enough aniline to produce 0.0322 mol acetanilide. This means that the amount of acetanilide actually produced is limited by the aniline, which is therefore the limiting reagent. Answer: Limiting reagent is aniline.

What is the principle on the acetylation of acetanilide?

Principle: Acetanilide is synthesized from aniline by acetylating it with acetic anhydride in presence of glacial acetic acid. Aniline or phenylamine is a primary amine and basic in nature. Acetic anhydride, an anhydride of acetic acid, acts here as a source of acyl group.

Which chemical can be used instead of acetic anhydride for the synthesis of acetanilide?

Acetyl chloride could work, but it is more reactive, and should be tested to validate your procedure. Try propionic Anhydride it should work .

How do you calculate theoretical yield of acetanilide?

PROCEDURE

1. 10 g of aniline shall yield acetanilide = 135.16 / 93 × 10 = 14.5 g.
2. Then, Percentage Practical yield = Practical yield / Theoretical yield × 100.
3. = 12 / 14.5 × 100 = 82.75 %

What is the theoretical mass of acetanilide?

So the theoretical yield of acetanilide is 0.160g.

Which green reagent is used in acetylation of aniline?

Add 0.45 mL of concentrated hydrochloric acid. Measure out 0.6 mL of acetic anhydride and prepare a solution of 530 mg of sodium acetate in 3 mL of water. Add the acetic anhydride to the solution of aniline hydrochloride in water, mix by swirling, and immediately add the sodium acetate solution.

What is the theoretical yield of acetanilide?

Why glacial acetic acid is used in bromination of acetanilide?

Glacial acetic acid is not frozen ( cold) acetic acid. It is a common term used Glacial acetic acid is not frozen ( cold) acetic acid. This is why glacial acetic acid is used. Bromination of aromatic compounds (like aniline) using Bromine (Br2) takes place by electophilic aromatic substitution mechanism.

What is the theoretical mass of Acetanilide?

What is the molar mass of Acetanilide?
