Practise Post Lab Questions for Heating under reflux-Wintergreen oil HERE IS A LITTLE BACKGROUND INFORMATION AND SEE PICTURE FOR DATA COLLECTED Background Information: PURPOSE Convert wintergreen oil into salicylic acid using aqueous base. Hydrolyze esters under basic conditions Reflux a reaction Perform a vacuum filtration Esters can be converted to carboxylic acids under acidic or basic conditions. Typically, the ester can be mixed with aqueous acid or base and then briefly refluxed in order to hydrolyze the ester. In this experiment, hydrolysis will be accomplished under basic conditions. Saponification refers to the process of converting carboxylic acids to carboxylate salts. This process is commonly used on long chain acids in order to form soaps. After saponification, the dianion will be recovered by acidifying the solution.In this experiment, a minimum of 2 equivalents of the base is needed. The first equivalent will deprotonate the phenolic group of methyl salicylate. This…
