However, the benzylic position of Fluorene can be oxidized in basic conditions byoxygen with a catalyst such as Aliquat 336 (ticapryxlmethylammonium chloride).Caution: NaOH is toxic and corrosive. Avoid contact and wash affected area immediately with water.Waste: Any hexane filtrates should be disposed of in the Red solvent waste recovery canister. Aqueous filtrates may be poured down the drain.Procedure: Mix 0.8 g of fluorene with 8 mL of hexanes (bottle top dispenser) in a 50 mL Erlenmeyer flask with a stir bar. Add 4 mL of 10 MNaOH (use gloves). Add 10 drops of Aliguat 336 and stir the mixture vigorously for 1 hour. The stirring rate should produce a froth on thesurface. Transfer the reaction to a 15 mL centrifuge tube or test tube, cool in an ice bath for 2-3 minutes and carefully remove the lower aqueouslayer with a pipet. Collect the solid, crude fluorenone on a Buchner funnel via vacuum filtration. Wash with small amount of 1 M HCl (~2 mL)and then water.Dry the sample on the filter for a few minutes. Get a mass of the product before continuing.Recrystallize the crude product from cyclohexane. Dissolve your product in a minimum of hot cyclohexane (generally ~13 mL/gramcrude product) and cool to RT, then an ice bath until product crystals form. Do not cool too long. You will freeze the cyclohexane. Filter therecrystallized product.Dry and obtain the mass and melting point. Obtain an IR using KBr.

Analyzing Infrared Spectra

The electromagnetic radiation or frequency is classified into radio-waves, micro-waves, infrared, visible, ultraviolet, X-rays and gamma rays. The infrared spectra emission refers to the portion between the visible and the microwave areas of electromagnetic spectrum. This spectral area is usually divided into three parts, near infrared (14,290 – 4000 cm-1), mid infrared (4000 – 400 cm-1), and far infrared (700 – 200 cm-1), respectively. The number set is the number of the wave (cm-1).

It is the analysis of the structure of cyclohexaone using IR data interpretation.

IR Spectroscopy

Infrared (IR) or vibrational spectroscopy is a method used for analyzing the particle's vibratory transformations. This is one of the very popular spectroscopic approaches employed by inorganic as well as organic laboratories because it is helpful in evaluating and distinguishing the frameworks of the molecules. The infra-red spectroscopy process or procedure is carried out using a tool called an infrared spectrometer to obtain an infrared spectral (or spectrophotometer).

NaOH (use gloves). Add 10 drops of Aliguat 336 and stir the mixture vigorously for 1 hour. The stirring rate should produce a froth on the
