Experiment VI: Oxidation of Isoborneol with Bleach Purpose: In this experiment‚ Green chemical procedures were applied to oxidize isoborneol to camphor using bleach (NaOCl)‚ rather than the tradition chromium-based oxidizing reagents. The camphor was then purified using the process of sublimation. Procedure: Using a 50-mL Erlenmeyer flask‚ 1.316 g (8.5 mmol) isoborneol and 1.0 mL (17 mmol) glacial acetic acid were stirred vigorously with a magnetic stir plate. A volume of 1.7 mL NaOCl

Borneol; An Oxidation-Reduction Scheme Nicolas Gibson Lab Time: Tuesday 11:30 am Abstract: In this experiment‚ the main objective was to synthesize a ketone from borneol via an oxidation reaction and secondly‚ to produce a secondary alcohol from camphor via a reduction reaction. Therefore‚ the hypothesis of this lab is that camphor will be produced in the oxidation reaction and isoborneol will be the product of the reduction reaction because of steric hindrance. For the oxidation

Theory‚ Reactions‚ and Mechanisms In this lab‚ Borneol will be oxidized to camphor in a common reaction known as the Jones Oxidation Reaction. It is true that oxidation reactions subtract electrons‚ lowering its oxidation state. However in organic chemistry‚ a more detailed explanation of the oxidation

Introduction: Borneol (FIGURE-1)‚ first reported and published in the Tang Bencao in 659 A.D.‚ is often used in drug treatment‚ especially in Chinese drugs. It is helpful in opening obstruction of orifices‚ heat syndromes and pain releasing (Dharmananda). Nowadays artificially synthesized borneol‚ a mixture of borneol and isoborneol (FIGURE-2)‚ becomes more popular than pure natural borneol because of the lower cost in drug production. However‚ isoborneol is more toxic than borneol and thus is not

impossible to reach‚ and 10C-15C variation is acceptable. Questions 1). The infrared reading comparison between camphor and borneol+isoborenol is that camphor does not have a OH-stretch at 3400‚ but it does have a C=O stretch around 1700-1750 that borenol and isoborneol doesn’t have. The IR readings of isoborneol and borneol look very similar the major difference is that isoborneol has a higher intensity reading from the 1500-1000 wavenumbers. 2). The peaks are different due to the position of the

Oxidation of Borneol to Camphor Abstract: This lab converted borneol to camphor using a green oxidation. Sodium hypochlorite was used instead of the less “green” Jones reagent. Borneol was mixed with glacial acetic acid and oxidized with sodium hypochlorite to make crude camphor. The crude camphor was purified by sublimation. The final product was characterized by obtaining a melting point and inferred spectroscopy. The experiment was carried out to see if bleach could oxidize borneol and if it
