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...

acetic acid is 25 ml and alcohol is 20 ml
The synthesis of an ester by the reaction of a carboxylic with an alcohol is an equilibrium reaction. H - R-OH HO ROH R OR, Recall from general chemistry that, according to Le Caiclista principle, an equilibrium can be shifted toward greater product formation by using an excess of reactant or by removal of a reaction product as it forms. 1. Are any products removed during the reaction period (the...
