The chemical reaction between acetic anhydride and salicylic acid is called esterification. This reaction forms acetylsalicylic acid, which is commonly known as aspirin.
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.
The reaction between salicylic acid and acetic anhydride involves the substitution of a hydroxyl group in salicylic acid with an acetyl group from acetic anhydride. This reaction is catalyzed by an acid, typically sulfuric acid, and results in the formation of aspirin and acetic acid as byproducts.
A reaction between an alcohol and an anhydrid is usually exothermic, so I would say it is.
The chemical reaction mechanism between maleic anhydride and anthracene involves a Diels-Alder reaction, where the maleic anhydride acts as the dienophile and the anthracene acts as the diene. This reaction forms a cyclic compound called anthracene-maleic anhydride adduct.
acetic an hydride formula is (CH3CO)2O in salicylic acid for benzene ring OH and COOH are present ortho to each other. When we terate the acetic an hydride with salicylic acid, Hydrogen as a positive charge from slicylic acid (from OH not from COOH) and CH3COO as a negetive chare will replaces and finally acetyl salicylicylic acid will form,it is also called as ASpirin.acetic acid is also forms

Aspirin is formed in a reaction between salicylic acid and acetic anhydride. In this reaction it is the phenolic alcohol group that reacts to form the aspirin.

The reaction between acetyl chloride and sodium acetate would likely result in the formation of acetic anhydride and sodium chloride. Acetyl chloride would react with the sodium acetate to form acetic anhydride, along with sodium chloride as a byproduct.
Phosphoric acid is used in the synthesis of aspirin as a catalyst to facilitate the esterification reaction between salicylic acid and acetic anhydride. It helps increase the reaction rate and yield of aspirin.
If the sulfuric acid is left out of the reaction, the acetylsalicylic acid synthesis may proceed at a slower rate or not to completion. The presence of sulfuric acid helps catalyze the reaction and improves the yield of acetylsalicylic acid. It also helps in the dehydration of acetic acid formed during the reaction.
Phthalic anhydride and resorcinol undergo a condensation reaction to form a compound called resorcinol phthalic anhydride resin. This reaction typically occurs in the presence of a catalyst, such as sulfuric acid, and at elevated temperatures around 150-200°C. The reaction leads to the formation of a polymeric material with good thermal and chemical resistance properties.
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.
Aspirin is generally produced by the following mechanism (starting from basic materials) Phenol --(NaOH, CO2, heat)--> Sodium Salicylate (+para isomer) --(H2SO4)--> Salicylic acid --(acetic anhydride)--> acetylsalicylic acid (Aspirin) Due to the myriad of organic reactions, there are multiple possibilities at each stage. However, the above is the most efficient and common way of synthesizing Aspirin. For example, the last reaction (esterification) may be accomplished by using an acyl halide instead of an anhydride (e.g. ethanoyl/acetic chloride instead of acetic anhydride). However, the acyl halide is more costly to synthesize and more unstable to handle.
