Synthesis of Aspirin from Oil of Wintergreen Objectives: In this experiment‚ the Oil of Wintergreen is put into an Erlenmeyer flask containing sodium hydroxide to create sodium salicylate. The solution is then refluxed which means that the solution will be boiled in a base‚ then condensed in a condenser. This replaces the carbon on the ester at carbon 1‚ with an oxygen atom which will have an ionic bond with a sodium anion. This yields sodium salicylate which will be acidified in methanol
