    occurred so fast that much of the solvent is contained in the crystals. So the actual melting point is nearly 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

But how can we synthesize borneol in a way that gives more borneol than toxic isoborneol? An experiment of making borneol from camphor (FIGURE-3) is performed in two different methods‚ Sodium Borohydride Reduction and Meerwein-Ponndorf-Verley Reduction‚ to compare the relative product ratio of borneol to isoborneol. The concept of reduction and also oxidation‚ the opposite procedure

    Experimental Part 1: Reaction First the glassware apparatus for the reaction was set up. 3.861-grams of isoborneol‚ 2.21-mL of glacial acetic acid‚ and 4.39-mL of 6% NaOCl solution were mixed in a 125-mL Erlenmeyer flask. Another 35-mL of 6% NaOCl solution was added to a separatory funnel and supported over the flask. The NaOCl in the sep funnel was slowly added into the Erlenmeyer flask with vigorous swirling‚ approximately 2-mL every 30 seconds until all the NaOCl from the sep funnel had been

  • Hypochlorite Oxidation of endo-Borneol to Camphor

    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. Procedure and ObservationsPlease refer to the lab manual and the carbon copy attached. Data and CalculationsWeight of endo-borneol = 0.2013gNo of moles of endo-borneol = 0.2013g/154.25g mol-1 = 1. 305mmolSince one mole of endo-borneol should give one mole of camphorTheoretical yield of camphor = (1.305 mmol )( 152.23g mol-1)

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 reaction is appropriate for

  • Borneol: An Oxidation-Reduction Scheme

    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 step‚ a reflux will be done and then a microscale reflux for the reduction step. The products will be confirmed using Infrared spectroscopy‚ the chromic acid test‚ 2‚4-DNP test and 13C NMR spectroscopy. The results of this experiment show that camphor was produced
