Because Salicylic Acid reacts with Acetic Anhydride in the presence of H2SO4 and CH3COOH to give Aspirin. The sulphuric acid does not react. If you measure the volume/weight of the acid before the reaction and after the reaction, there will be no change. Note:-
You can also use Acetyl Chloride in the presence of phosphoric acid instead on Acetic Anhydride.
Salicylic acid acetyl is made by reacting salicylic acid with acetic anhydride in the presence of an acid catalyst, such as sulfuric acid, to form acetylsalicylic acid. This reaction causes the hydroxyl group (-OH) of salicylic acid to be acetylated, resulting in acetylsalicylic acid, commonly known as aspirin.
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.
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
The process of making aspirin in pharmaceutical manufacturing involves combining salicylic acid with acetic anhydride in the presence of a catalyst, such as sulfuric acid. This reaction forms acetylsalicylic acid, which is the active ingredient in aspirin. The mixture is then purified, crystallized, and dried to produce the final aspirin product. Quality control measures are implemented throughout the process to ensure the purity and consistency of the aspirin tablets.
to convert the phthalic anhydride in to phthalimide, it is heated with urea at the temp. of 160 c with out using any solvent. phthalic anhydride + urea = phthalimide +water+ carbondioxide

Sulfur trioxide is commonly known as sulfuric anhydride or sulfuric oxide.
The process of making aspirin in pharmaceutical manufacturing involves combining salicylic acid with acetic anhydride in the presence of a catalyst, such as sulfuric acid. This reaction forms acetylsalicylic acid, which is the active ingredient in aspirin. The mixture is then purified, crystallized, and dried to produce the final aspirin product. Quality control measures are implemented throughout the process to ensure the purity and consistency of the aspirin tablets.
Salicylic acid + acetic anhydride react to form acetylsalicylic acid (aspirin) + acetic acid. This reaction is performed in acidic conditions ( normally by adding sulfuric acid) and is heated.
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.
Sulfur trioxide - SO3 + H2O -----> H2SO4
to convert the phthalic anhydride in to phthalimide, it is heated with urea at the temp. of 160 c with out using any solvent. phthalic anhydride + urea = phthalimide +water+ carbondioxide
The common name for sulfur trioxide is sulfuroxide.
The chemical name for sulfur trioxide is sulfuric anhydride.
Sulphuric anhydride is H2S2O7,... H2SO4 + H2SO4-----> H2S2O7 + H2O
