What is the purpose of phosphoric acid in the synthesis of aspirin?

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.


Why pyridine is used im the synthesis 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.


Why maintain the temperature of the reaction at 90 degrees C in synthesis of aspirin?

Maintaining the temperature at 90 degrees C in the synthesis of aspirin helps to achieve optimal reaction kinetics, ensuring the reaction proceeds at a suitable rate. This temperature also promotes the formation of the desired product while minimizing the formation of unwanted byproducts.


Why is an esterification reaction referred to as an elimination reaction?

Because a water molecule is a product of the reaction


The reaction in which two or more substances react to form a single substance?

This type of reaction is known as a synthesis or combination reaction. It involves the combination of two or more substances to form a single product. An example is the reaction of hydrogen gas and oxygen gas to form water.

What is the process of making aspirin?

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.


Is aspirin synthesis an exothermic reaction?

yes


What is the chemical reaction between acetic anhydride and salicylic acid?

The chemical reaction between acetic anhydride and salicylic acid is called esterification. This reaction forms acetylsalicylic acid, which is commonly known as aspirin.


Mechanism of aspirin synthesis?

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.


What is the polymeric byproduct in the preparation of aspirin?

esterification of 2 salicylic acid molecules


How do you write esterification equations?

Esterification Reaction: When an alcohol ( mostly primary) alcohol is treated with carboxylic acid in the presence of H2 SO4 sweet smelling compound is formed which is called ester. The reaction is know as esterification reaction.


Meaning of esterification?

esterification is the formation of esters between the reaction of alkanol and alkanoic acid


What is an alternative reagent to ethanoic anhydride in the synthesis of aspirin from salicylic acid?

Synthesis of acetyl chloride via the reaction of acetic acid with sulphuric acid
