SYNTHESIS OF SALICYLIC ACID The purpose of this experiment is to synthesize salicylic acid, a white organic solid that was extracted from willow bark by Hippocrates in the fifth century BC. As the reaction proceeds, the solid salicylic acid disappears and the acetylsalicylic acid product remains dissolved in the hot solution. Aspirin’s chemical name is acetylsalicylic acid, and it is synthesized from the reaction of acetic anhydride with salicylic acid in the presence of phos-phoric acid as a catalyst. Usually, esters are derived from a carboxylic acid and alcohol. -Isolating a natural product and identifying its medicinal properties-Chemically synthesizing a new drug. ABSTRACTIn chemical engineering or in chemical subject, there is a chemical compound named esters. Test. Flashcards. Hippocrates’ discovery was lost over time, but re-discovered in the mid 1700’s. STUDY. An ester is a compound that is formed when an acid reacts with an alcohol, -OH group. These molecular entities were created by covalently linking two bioactive molecules, either niacin or salicylic acid, to an omega-3 fatty acid. Principle: Alkaline hydrolysis of esters is called saponification and is an irreversible process. So, concentration of salicylic acid in my ASA product is ± 1.5%. Since the limiting reagent is the reactant that is completely consumed in the reaction we need to calculate moles.
