    bottom and thus allowing it to be separated. The total amount of 1-bromobutane formed was 2.065 grams. In order to confirm that the reaction occurred correctly and that 1-bromobutane was formed‚ infrared spectroscopy as well as halide tests were performed on the product. Infrared spectroscopy works on the basis that different covalent bonds of molecules can stretch and bend. These bonds can undergo vibrations which require energy that corresponds directly with the energy absorbed from infrared

    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 during oxidation (0.6576 g). The IR spectrum shows a strong peak at 1740 cm-1 representing a carbonyl compound‚ which was concluded to be a ketone by

    experiment was to efficiently perform an Fischer esterification of 1-butanol and acetic acid to form water and n-butyl acetate‚ and to confirm the esterification using IR spectroscopy analysis. It was found that 0.734 grams of n-butyl acetate was formed with a percent yield of 61%. The product was confirmed using IR spectroscopy and boiling point confirmation. The reaction mechanism for this specific reaction was as follows: First the protonation of a carbonyl oxygen activates the carboxylic acid

    Introduction Esters are in a lot of natural products like flowers‚ spices and fruits. They are usually used in artificial flavorings. Carboxylic esters help amplify the sensory effect of esters. Isopentyl acetate is made from the direct esterification of acetic acid and isopentyl alcohol. The direct esterification of acetic acid and isopentyl alcohol is an equilibrium reaction that shifts the product to the side by using the excess of one of the starting reagents. Acetic acid usually used in excess

    Case study A blue paint layer sample was collected from the wall decorations of the mortuary temple of Ramesses III (Medinet Habu. This temple is one of the largest memorial temples in Egypt. It measures 320 m in length (east to west) and about 200 m in width (north to south)‚ built with order of the Pharaoh Ramesses III (c.1184–1151 BC the 20th Dynasty). The micro-XRF spectrometer (SPECTRO‚ COPRA model) used to analyze the sample includes a side-window X-ray tube with Mo anode (Oxford Instruments

    to study in vitro the permeability of amorphous drug systems in different conditions. First‚ three complementary techniques are performed to characterize the crystalline and amorphous form of indomethacin. These techniques include IR spectroscopy‚ Raman spectroscopy and differential scanning calorimetry. Indomethacin is a compound belonging to class II of the BCS and is consequently a poorly water-soluble drug. The limiting step in order to have a good bioavailability is the dissolution step.
