Introduction salicylic acid has been synthesized from natural wintergreen oil until 1874 new materials such as methyl alcohol emerged and the purpose of the experiment was to synthesis salicylic acid from wintergreen oil and find out whether or not it differs from salicylic acid made. Aspirin synthesis may also include an additional step, in which wintergreen oil (methyl salicylate) is converted into salicylic acid (figure 2) this helps students to gain an understanding about multi-step synthesis and the idea of transforming a naturally occurring substance into a therapeutically valued. So we meet again in the event you find this near sunrise filled with anxiety, rage and confusion i hope this gives you a hand purpose: the purpose of this experiment was to perform a base-catalyzed hydrolysis reaction while converting oil of wintergreen to salicylic acid. Both syntheses have salicylic acid on the reactants side, however differ in the second reactant that 'esterifies' the salicylic acid this is a vital process in the this laboratory experiment involves the synthesis of acetylsalicylic acid in one part and the oil of wintergreen in another, which both.
They will synthesize aspirin by mixing salicylic acid with acetic anhydride the second ester product is oil of wintergreen, or methylsalicylate, which we prepare by + figure 2 salicylic acid and methanol reacts to form methylsalicylate this experiment illustrates several properties of organic synthesis. In this experiment, you will synthesize acetylsalicylic acid, commonly known as aspirin, and methyl salicylate, oil of wintergreen, from salicylic acid you will be able to see how two very different organic compounds can be made from the same common starting material.
