Synthesis of aspirin (acetylsalicylic acid) follows the reaction as represented by the above balanced equation.
As per above equation acetic anhydride and salicylic acid reacts in
The amount of acetic anhydride in
Now by the equation
But the amount of salicylic acid actually taken is
So this is the limiting reagent.
We are to calculate the theoretical yield with respect to this reagent.
Now by the above equation we know that
So theoretical yield of aspirin
