Step 1
First, we need to understand the reactions involved in the gelation process. The main reactions are: a) Glycerol (G) reacts with phthalic anhydride (PA) to form a monoester (ME) and water: G + PA → ME + H2O b) Ethylene glycol (EG) reacts with Show more…

Calculate the theoretical yield of aspirin if you start with 2.687 g of salicylic acidand an excess of acetic anhydride
Madhur L.
Using the equation below for the synthesis of aspirin: OH H2SO4 OH OH OH salicylic acid acetic anhydride aspirin acetic acid Assuming we used 3.5 g of salicylic acid and 20.00 g of acetic anhydride (sulfuric acid is the catalyst, so no need to consider it for this calculation), calculate the theoretical yield of aspirin. p} In the same reaction, if we recovered 1.6 g of aspirin, what is the percentage yield?

What is the theoretical yield of aspirin in your synthesis? The mole ratio is 1:1 between salicylic acid and acetic anhydride in this reaction. Show calculations please.
