  • The Estainability Of First Generation Biofuels

    University, involves the use of a hydro-deoxygenation catalyst using supported noble metal nanoparticles. [8] Catalysts are extensively used in industry to facilitate and speed up chemical reactions. Hydro-deoxygenation is a reaction that can give alkanes as a final product that can be used directly as a fuel in conventional engines. This happens by removing oxygen from the biomass feedstock. To achieve that a catalyst is required that will aid in breaking the carbon-oxygen bonds in the biomass.…

  • Dehydration Lab Report

    show a stretch between 1620-1680 cm-1, but the frequency depends on the level of conjugation. The peaks approximately at 3050-3150 cm-1 shows the alkene (sp2 hybridized) CH stretch in figure 8. While, the downfield peak around 2840-3000 cm-1 is the alkane sp3 CH stretch. The peak approximately between 1300-1400 cm-1 indicates the CH2 bend. The difference between figure 5 and 8 is the presence of OH peak at 3342 cm-1 in figure 8 that clearly explains the pureness of cyclohexene. An…

  • Copper Calorimeter Experiment

    This experiment’s aim was to find the alcohol with the highest energy output when burnt using specific heat capacity of calorimeters. This data gathered only partially supported the hypotheses stated. There is an apparent trend between the heat energy of the alcohols and the amount of carbon atoms in the alcohols in the graphs shown. The first experiment (first graph) shows the results of the tests with a controlled calorimeter height of 20 centimeters. This means that the calorimeter, rather…

  • Iodobutane Lab Report

    After deprotonation of 6.8 mmol naphthalen-2-ol by 14.0 mmol NaOH, the resulting anion was placed together with 8.8 mmol 1-iodobutane, and the reaction was performed by reflux in 20 mL of ethanol (EtOH) solvent, and the product was allowed to cool on ice and collected by suction filtration. The final crystals had a very pale amber color and were odorless. The following week, after being allowed to completely dry for a week at room temperature, the IR spectrum of the product in liquid suspension…

  • Elements In The Periodic Table

    The sixth element in the periodic table is one of the most important elements of them all, carbon. This element, located on group fourteen and period two of the periodic table, has an atomic number of 6 and a molar mass of 12.01; this means that it has 6 electrons, 6 protons, and 6 neutrons. The element is lightweight, fairly small, the fourth most abundant element on Earth, and is essential for living, growing, and reproducing. Carbon is found in all living and non-living organisms, in the form…

  • Reflection Of Cooperative Learning In The Chemistry Of Life

    I attended schools in China for sixteen years and have experienced one of the most tiring education systems; we have to stay at school from 8:00 am to 6:00 pm. However, this way of learning through lectures did not make me have a solid grasp of the topic I learned. In order to change my way of learning, my parents sent me to the United States, as the U.S. education system is highly valued. It is true that the the teaching method is totally different from what I experienced before. In the high…

  • Comparison Of Organometallic Compounds

    Comparison of Organometallic Compounds of Transition Metals and Main Group Elements Organometallic Compounds: The compounds which contain at least one direct metal to carbon covalent bond are known as organometallic compounds many of these are thermodynamically unstable and are pyrophoric. The meta may belongs to main group, transition metal, f group metal or a metalloid i.e. selenium, boron, arsenic, silicon, antimony, germanium, and tellurium and the carbon moiety may be alkyl, alkene, alkyne,…

  • Curcuma Longa Case Study

    2.1 Test materials: The essential oils of Curcuma longa (Zingiberaceae) rhizomes, Pogostemon heyneanus (Lamiaceae) leaves and Zanthoxylum limonella (Rutaceae) fruits were obtained from a commercial oil extraction plant in Assam, India. DMP was supplied by High Purity chemicals, New Delhi, India while DEPA was obtained from Defence Research and Development Establishment, Gwalior, India. Four concentrations (5, 10, 20 and 30%) of the essential oils, their mixtures, DEPA and DMP were prepared in…
