What is the purpose of phosphoric acid in the synthesis of aspirin?
to serve as a catalyst and speed up the reaction
Why maintain the temperature of the reaction at 90 degrees C in synthesis of aspirin?
To prevetn evaporation of salicylic acid
Why is saponification reaction is considered to be the reverse of an esterification reaction?
saponification is considered to be the reverse process of an esterification reaction due to the fact that esterification is combining an alcohol and a carboxylic acid but a saponification is breaking apart the ester by adding an NaCl molecule (soap) to the chain of carbons.
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?
A synthesis reaction or dehydration synthesis, also called a condensation reaction.
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
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.
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.
What is the purpose of phosphoric acid in the synthesis of aspirin?
to serve as a catalyst and speed up the reaction
Meaning of esterification?
esterification is the formation of esters between the reaction of alkanol and alkanoic acid
Why maintain the temperature of the reaction at 90 degrees C in synthesis of aspirin?
To prevetn evaporation of salicylic acid
What is the polymeric byproduct in the preparation of aspirin?
esterification of 2 salicylic acid molecules
What is the name of the reverse reaction of esterification?
hdrolysis

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
