Cyclohexanone Lab Report

In the first experiment, cyclohexanol was oxidized to form cyclohexanone. This was accomplished by pouring 2.0 ml of cyclohexanol and 1.0 ml of acetic acid into a 250 ml Erlenmeyer flask. Under a fume hood, slowly add 30 ml of bleach, and oxidizing agent, to the mixture and stir for 20 minutes. Acetic acid will react with bleach to make it a better oxidizing agent and form hopochlorous acid. Hypochlorous acid will then oxidize cyclohexanol. The mixture turned cloudy during the process but clear up after a few minutes. The flask will be warm since this is an exothermic reaction. Next, the mixture will be tested using potassium iodide-starch test. If the test is positive then proceed but if not then add an extra 5.00 ml of bleach and stir for 5 minutes. …show more content…
Be sure to stir the mixture for 2 minutes after adding sodium thiosulfate. Repeat the potassium iodide-starch test to make sure that there are no oxidize agent left in the mixture. Once done, the mixture will be tested for it pH level. If the mixture is too acidic, then add sodium bicarbonate, as necessary, to reduce acidity. In the next step, add enough sodium chloride so that a small amount will remain after stirring. This will decrease the solubility of organic compounds and increase the amount of product that can be collected. Decant the liquid part of the mixture into a separatory funnel. Wait 5 minutes for the layers to separate and then drain the bottom layer into the Erlenmeyer flask and the top layer into a vial. Use a small pipette to take out any bubble in the vial. Add a small amount of sodium sulfate, a drying agent, to the vial and let it sit for 5
