[PDF] acetylation of aniline using acetic anhydride

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. Cool the solution in an ice bath and collect the solid acetanilide by vacuum filtration.

  • What is the mechanism of acetylation of aniline using acetic anhydride?

    Aniline reacts with acetic anhydride to form Acetanilide by nucleophilic substitution reaction and the reaction is called acetylation. In this reaction, aniline acts as the nuclepohile and acyl (CH3CO-) group from acetic anhydride acts as the electrophile.30 mai 2023

  • What happens when aniline reacts with acetic anhydride?

    Acetanilide is prepared from aniline when it reacts with acetic anhydride/glacial acetic acid in the presence of zinc dust.

  • What is the acetylation of aniline using acetic acid?

    - The acetic anhydride reacts with aniline, the reaction is known as ethanoylation or acetylation reaction, which produces a product which is named as acetanilide and acetic acid is another product.
  • Here, salicylic acid is subjected to acetylation with the help of acetic anhydride to yield acetylsalicylic acid (commonly known as aspirin) and acetic acid as the final product. It can be noted that acetic anhydride is also used as an acetylating agent in the synthesis of THC acetate ester and diacetylmorphine.
