We will carry out this reaction both to illustrate the Williamson synthesis and to identify‚ by the melting point of the product‚ which isomeric cresol was issued to you. Procedure: 1) Dissolve 4 g of KOH in 8 mL of water in a 250mL round bottom flask. 2) Add 2 grams of your mystery cresol (x‚ y‚ or z) to the round bottom flask in the hood. Swirl the mixture until a homogeneous solution results. Add 3 boiling stones. 3) Fit the flask with a reflux

prepared by a process known as saponification. Historically‚ soaps were made by boiling the fat of animal‚ lye and in a aqueous NaOH and KOH solution containing potash. Of course‚ this was done long time ago before anyone had any idea of understanding the chemical transformations. Now‚ we know that this process is a reaction of esters with a strong base such as KOH or NaOH. The esters‚ triglycerides are the main constituents of vegetable oil and animal fats.
