find the theoretical yield of the acetysalicylic acid .
EXPERIMENT 19 PREPARATION OF ASPIRIN In addition to the Fischer esterification method presented in Experiment 18, a second method for preparation of esters involves the reaction of anhydrides with the hydroxyl This method is ospecialy usoful for tho preparation of acetate esters, since acetic anhydride is an inexpensive and reactive reagent. In this experiment the hydroxyl group of salicylic acid is acetic anhydride to make acetylsalicylic acid, or aspirin. The short...
3. Calculate the theoretical yield of acetylsalicylic acid from 2.20 g of salicylic acid assuming the salicylic acid is the limiting reactant. [3] 4. Assume that 1.65 g of acetylsalicylic acid is produced from the reaction above. Calculate the percent yield. [2]
10. Calculate the theoretical yield of aspirin using 4.00 g of salicylic acid as the starting material. Assume acetic anhydride is in excess. (Hint: from the mass of salicylic acid acid use, how many moles of salycilic acid are present intitially? What is the salycilic acid : acetylsalicylic acid molar ratio? How many moles of acetylsalicylic acid are formed assuming 100% yield? Based on this abount of moles, how many grams of acetylsalicylic acid are formed? (this is the theoretical...
