Green 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

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)

solids – ionic and molecular. The samples used are sodium chloride (ionic) and camphor (molecular). The physical properties studied are odour‚ hardness‚ melting point‚ solubility in water and solubility in 2-propanol. It is observed that some of the physical properties of sodium chloride are no odours‚ hard‚ a high melting point‚ soluble in water and insoluble in 2-propanol; some of the physical properties of camphor are a strong odour‚ soft‚ a low melting point‚ insoluble in water and soluble in

18th and 19th century‚ it became well known that chemicals such as camphor can induce seizures to help with mental illness.1 In 1934‚ a Hungarian psychiatrist‚ Ladislaw Meduna‚ empirically pursued his theory on the relationship between seizures and schizophrenia using camphor oil. He wanted to see if he could cure a patient with catatonic schizophrenia by inducing epilepsy in the patient through injecting the patient with the camphor oil. After several of these treatment sessions‚ the patient was reportedly

You can do this while you are at home‚ at work or before doing your workout. VapoRub incorporates levomenthol‚ a strong white glass with mint flavor. If ever that this part is utilized alone‚ it might cause rash‚ however when paired up with Vicks‚ it is totally safe because of the fact that it incorporates eucalyptus oil. Camphor is another
