An oxidation-reduction scheme: borneol, camphor, isoborneol 1 this experiment will illustrate the use of an oxidizing agent (hypochlorous acid) for converting a. Hypochlorite oxidation of endo-borneol to camphor essay acetic acid mixture was used to oxidize emdo- borneol (an alcohol) to camphor (a ketone) the product would then be purified by sublimation and then be analyzed by infrared spectroscopy and melting point test. Through an oxidation-reduction reaction sequence, borneol is converted to isoborneol first, borneol is oxidized through a reaction with sodium hypochlorite at 400c to form camphor when the camphor is then reduced by sodium borohydride, isoborneol is formed the percent yeild of isoborneol. Hypochlorite oxidation of endo-borneol to camphor bond cleavage of chlorine:in the first step of reaction mechanism of hypochlorite oxidation of endo-borneol to camphor, a hydroxyl proton was replaced by the positive chlorine.
Oxidation and diastereoselective reduction borneal to camphor to isoborneol objective: the purpose of the experiment was to see between which diastereomer borneol (endo) or isoborneol (exo) is comparatively more better for camphor with sp2 hybridized carbon makes a stereocenter. The reduction of camphor favored the production of isoborneol over borneol as opposed to an equal combination this is because when the sodium borohydride attacks the camphor, it would attack in the endo-phase due to the steric strain caused by the two geminal methyl groups on one side of the cyclohexane ring.

Six monoterpenes significantly more potent than camphor were identified: 6-tert-butyl-m-cresol, carvacrol, dihydrocarveol, thymol, carveol and (+)-borneol their ec 50 is up to 16 times lower than that of camphor.
Expect that camphor can be separated from unreacted borneol using sublimation because there is a large difference in their vapor pressures since the vapor pressure of camphor is 065mmhg at 25°c and the vapor pressure of borneol is 335mmhg at 25°c and the sublimation is taking place in a vaccuum, both will vaporize, but only camphor will re-solidfy on the cold finger at a high temperature.
