acetaminophen (n-acetate of 4-aminophenol)
Adding a small amount of acetic anhydride helps to facilitate the acetylation reaction with aniline, leading to the formation of acetanilide. The acetic anhydride serves as an acetylating agent that transfers an acetyl group to the amine group of aniline, resulting in the desired product. The use of an excess of acetic anhydride is avoided to prevent side reactions and to optimize the yield of acetanilide.
Because it can not form the acetyl group easily but above 1000 Celsius acetic acid may form acetic anhydride which may be used to produce acetyl ion. Acetylation by acetic acid using is possible by using cobalt chloride as catalyst with good yield
An amino group is more basic than a hydroxy group. The amine on p-aminophenol would be protonated, so it would no longer be nucleophilic. That leaves the hydroxy group as the only nucleophile that could attack the acetic anhydride. The major product is p-aminophenyl acetate.
The reaction between methylamine and acetic anhydride results in the formation of N-methylacetamide as the primary product. In this reaction, acetic anhydride reacts with methylamine to form an amide functional group. This reaction is a common method for the synthesis of amides in organic chemistry.
If excess acetic anhydride is not removed from the reaction vessel, it can lead to side reactions or undesired byproducts in the final product. It could also affect the purity of the desired compound and make purification more challenging. Additionally, it can pose safety hazards as acetic anhydride is a corrosive and hazardous chemical.

Add 4-aminophenol to acetic anhydride. The product is paracetamol.

Triacetate is a synthetic cellulose-based material made by acetylating cellulose with acetic anhydride to create a cellulose triacetate. This process involves combining cellulose with acetic anhydride under controlled conditions to achieve the desired degree of acetylation, typically resulting in a highly durable and wrinkle-resistant material used in textiles and film.
When zinc is reacted with acetic anhydride and glacial acetic acid, a complex called zinc acetate is formed. The reaction typically involves the displacement of acetic anhydride by acetic acid to form zinc acetate. The overall reaction is a redox reaction where zinc is oxidized and acetic anhydride is reduced.
Aniline reacts with glacial acetic acid to form N-acetylaniline as the primary product. This reaction involves the acetylation of the amino group of aniline by the acetic acid to form the acetylated product. The reaction is usually carried out in the presence of a catalyst like sulfuric acid to facilitate the acetylation process.
An anhydride is not an acid and not a base.
The balanced equation for the reaction between salicylic acid and acetic anhydride to form aspirin (acetylsalicylic acid) is: salicylic acid + acetic anhydride → aspirin + acetic acid.
Your question has the names right in it. Maybe it's the chemical formulas you want. In that case, salicylic acid is C7H6O3 and acetic anhydride is C4H6O3.
