To prevetn evaporation of salicylic acid
No, aspirin synthesis is not an esterification reaction. It involves the reaction of salicylic acid with acetic anhydride to form acetylsalicylic acid (aspirin) and acetic acid through an acetylation reaction. Esterification typically involves the reaction of an alcohol with a carboxylic acid to form an ester.
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.
Pyridine is used in the synthesis of aspirin as a catalyst to help facilitate the esterification reaction between salicylic acid and acetic anhydride. Its basic properties help neutralize the acidic byproducts formed during the reaction, which improves the yield of aspirin. Additionally, pyridine can also help dissolve the reactants and promote the formation of the desired product.
The formation of aspirin will proceed faster if acetic anhydride is used in place of acetic acid. However, acetic anhydride will hydrolyze in the presence of water to form acetic acid, slowing down the reaction.
The yield of aspirin refers to the amount of aspirin produced in a chemical reaction compared to the theoretical maximum amount that could be obtained. It is typically expressed as a percentage. Yield can be affected by factors such as reaction conditions, impurities, and side reactions.

Synthesis of acetyl chloride via the reaction of acetic acid with sulphuric acid
The reaction is: (CH3CO)2O + H2O = 2 CH3COOH
Aspirin is made when salicylic acid and acetic anhydride is reacted in the presence of an acid catalyst such as H2SO4. Acetylsalicylic acid (aspirin) and acetic acid is formed. The reaction is an esterification reaction.
Yes the temperature does matter the liquid needs to be hotter. The liquid is that the aspirin is in the faster the aspirin will dissolve.
No
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.
