1. Using a burette, measure the cyclohexene (6.0 mmol) and transfer to
a 125 mL erlenmeyer, along with acetone ([Cyclohexene] = 1 M). Add
a stirbar.
2. Cool the solution in an ice-bath for 10 minutes with magnetic stirring.
3. Meanwhile, in a 2nd 125 mL erlenmeyer, dissolve Oxone (15.6 mmol) in
deionized water ([Oxone] = 0.60 M).
4. Attach a ring-clamp right over your flask. Add a closed separatory
funnel, such that the bottom tip is partially inserted in the flask.
5. Add your Oxone solution into the separatory funnel.
6. When your cyclohexene solution is sufficiently cold, gently open the
bottom valve of the separatory funnel to add the Oxone solution.
Adjust the valve to obtain a flow of approximately 1–2 drops/second.
7. Once the addition is complete, rinse the separatory funnel with a few
millilitres of water.
8. Remove the flask from the ice bath, and allow the reaction to stir at
room temperature for 20 minutes.
9. After 20 minutes, add 12.5 M HCI (14.9 mmol) dropwise to the stirring
solution. Allow the reaction to stir for 10 minutes before proceeding
with liquid-liquid extraction (p.8).
