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 of reduction‚ deals mostly with electron transfer between atoms. It will not be elaborated here‚ but the reduction procedure involved in this experiment is basically adding hydrogens

Catalytic reduction of hexacynoferrate (III) The silver nanoparticles were used in the catalytic electron transfer reaction between hexacyanoferrate (III) and sodium borohydride‚ resulting in the formation of hexacyanoferrate (II) ions and dihydrogen borate ions. The redox reaction is depicted as: [BH4] - + 8[Fe (CN) 6] -3 + 3H2O H2BO3 - + 8[Fe (CN) 6] -4+ 8H+ The reaction can even proceed without a catalyst‚ but it has been reported that it is a slow reaction‚ which follows zero-order

Oxidation of Borneol to Camphor Objectives: The purpose of this experiment was to use oxidation to convert (1S)-(-)-borneol into (1S)-(-)-camphor‚ which was done via the use of reagents such as glacial acetic acid and sodium hypochlorite and laboratory techniques learned in previous labs. Afterward‚ the final desired product was obtained‚ and to characterize and ensure the purity of the product‚ further lab techniques were implemented.

CHAPTER 4 RESULTS AND DISCUSSION 4.1 Identification of camphor and menthol using gas chromatography – mass spectrometry (GC – MS) In this study‚ the presence of menthol and camphor were determined from 5 different locally produced medicinal topical ointment samples. Sample of Vick® VapoRub® and Hurix’s Massage Balm were purchased from local pharmacies‚ Bunga Cengkih Balm and Serai Balm samples were purchased from the grocery shop. Buah Pala Balm sample was purchased from the night market

The purpose of this lab was to measure the reduction potentials of metals and to understand how a reduction-oxidation relationship works to produce spontaneity. Lastly‚ these results were used to determine the Faraday’s constant and Avogadro’s number by electrolysis‚ which is chemical decomposition produced by passing an electrical current through a solution with ions. The primary objective of part one of this experiment was to discover how the properties of an electrochemical cell works. An electrochemical

Purpose: To find number of moles of Fe+3 which react with one mole of NH3OH+ in order to partially balance the equation: NH3OH+ + 2Fe+3 "" ? + 2Fe+2 and to find the missing product. Procedure: H2C2O4 and H2SO4 were titrated with potassium permanganate. The molarity of the permanganate was then found because the molarity of the H2C2O4 and H2SO4 were already known. Then hydroxylammonium chloride and ferric sulfate and water was titrated with known potassium permanganate to get the molarity of the

consistency Introduction: Redox reactions occur when both oxidation and reduction take place. All atoms can be assigned an oxidation number‚ which is a positive or negative number that help in determining the reducing and/or oxidizing agents in an equation. An increase in the oxidation number of an atom from one side of an equation to another side indicates oxidation. A decrease in the oxidation number of an atom indicates reduction. For example: 2AgNO3 + Cu Cu(NO3)2 + 2Ag In this equation‚ on the

objective for the experiment was to perform a reduction reaction on the ketone group of camphor to the OH group on isoborneol. In order to successfully synthesis the reactant to the product‚ NaBH4 was used as the main reagent to reduce the carbonyl double bond. One believes the formation of isoborneol was successfully due to the product’s percent yield‚ IR‚ and melting point. During the lab‚ .077 grams of isoborneol was yielded from the camphor reduction. In result‚ .077 g compared to an theoretical
