Place 2 ml (2.08 g) of aniline 30 ml of 10% NaOH solution in 250 ml conical flask, then add 3 ml (3.4 g) of benzoyl chloride slowly with vigorous shaking. Cork the flask and shake for further 15-20 min or till the odour of benzoyl chloride can no longer be detected.

Secondly, Which reagent is used for the Benzoylation of aniline?
Benzoylation of compounds those are containing active hydrogen such as phenol, aniline, alcohol etc. form benzoyl chloride in the presence of aqueous NaOH (Schotten Baumann reaction).
Simply so, Why is sodium acetate used in acetylation of aniline?
acyl substitution reaction on acetic anhydride with aniline to synthesize acetanilide. A solution of sodium acetate will be added as a base to deprotonate the water soluble intermediate and to liberate the product.
What is obtained on acetylation of aniline?
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. Aniline reacts with acetic anhydride to form Acetanilide by nucleophilic substitution reaction and the reaction is called acetylation.

What is Benzoylation reaction?
The Schotten Baumann reaction can also refer to the benzoylation of active hydrogen-containing compounds with the help of benzyl chloride and aqueous sodium hydroxide. It is generally observed that the acyl chlorides are converted into acylating agents of superior power when pyridine is used as the base catalyst.
Which reagent should be used for the acetylation of aniline?
Add the acetic anhydride to the solution of aniline hydrochloride in water, mix by swirling, and immediately add the sodium acetate solution. The solution becomes white as acetanilide precipitates.
What is the use of Benzanilide?
Benzanilide is used to make dyes, active pharmaceutical ingredients and perfumes. It is also used to study the influence of beta-cyclodextrin on photorearrangement of acetanilide, benzanilide and ethyl phenyl carbonate. Further, it is used as an amide model compound to study the reaction between the amide and epoxy.
What is formed when benzoyl chloride reacts with aniline in presence of sodium hydroxide?
What is formed when benzoyl chloride reacts with aniline in presence of sodium hydroxide. Solution : It is known as Schotten Baumann reaction.
Is Benzanilide polar?
Because of the nitrogen non-bonded electron pair with the carbonyl group, amides are very polar and the basicity is weaker than amines.
Which green reagent is used in acetylation of aniline?
Acetanilide
What is the role of NaOH in Benzoylation?
Principle: Insertion of benzoyl moiety instead of an active hydrogen atom present in hydroxyl (OH) primary amino (NH2) or secondary amino group (NH) is usually termed as benzoylation reaction. In the preparation of benzanilide, NaOH neutralizes the liberated HCl and also catalyze the reaction.
What happens when phenol reacts with benzoyl chloride?
Phenol reacts with ethanoyl chloride at room temperature, although the reaction isn’t as fast as the one between ethanoyl chloride and an alcohol. In order to get a reasonably quick reaction with benzoyl chloride, the phenol is first converted into sodium phenoxide by dissolving it in sodium hydroxide solution.
Why glacial acetic acid is used in preparation of Acetanilide from aniline?
Glacial acetic acid is used because it is an excellent polar protic solvent capable of dissolving acetanilide. The acetate ion is a poor nucleophile. If water is present, bromine will react with water, rather than with aniline.
Why does phenol react with ferric chloride?
The ferric chloride forms a complex with the phenol, provided they are both very dilute, and the complex, being a charge-transfer compound, happens to give a very strong spectral signal in the visible, therefore it acts as a colour test for phenols, although not every phenol gives it.
