    Acid Base Extraction The purpose of this laboratory assignment was two-fold, first, we were to demonstrate the extraction of acids and bases, finally, determining what unknowns were present. Second, we were to extract caffeine from tea. These two assignment will be documented in two separate entities. Introduction: Acid / base extraction involves carrying out simple acid / base reactions in order to separate strong organic acids, weak organic acids neutral organic compounds and basic organic sub...
  • Relative Reactivity Of Aniline's
    542 words
    Relative Reactivity of AnilinesAbstract: Various Aniline were tested with Br 2/HBr solution, the products were crystallized and melting points attained to verify relative reactivity. My assignment, 2, 4-Dibromoanisol, was prepared in a yield of 52% with a melting point of 55-58 C. Reaction: Mechanism: Procedure: Anisole (0. 35 mL, 0. 0378 mol) was obtained and placed in a pre-weighed 25 mL round bottom flask, along with 2. 5 mL of glacial acetic acid and a magnetic stir bar. Then the reaction a...

    Hot and Cold Winter is coming to the northern hemisphere, and with it, talk of central heating, gloves and scarves, snowfall, and record low temperatures. Monitoring temperatures is part of our everyday life - whether we " re talking about the weather, our bodies, central heating, or cooking. In the United States, we typically measure temperature in degrees Fahrenheit. But in other countries, such as England, you " ll get the weather forecast in degrees Celsius. Recipes will advise you to bake a...

    Asymmetric Epoxidation of Dihydronaphthalene with a Synthesized Jacobsen " catalyst Professor Abstract. 1, 2 was reacted with L- (+) -tartaric acid to yield (R, R) -1, 2- mono- (+) -tartrate salt. The tartrate salt was then reacted with potassium carbonate and 3, 5-di-term- to yield (R, R) -N, N'-Bis (3, 5-di-term-) -1, 2-cyclohexane diamine, which was then reacted with Mn (OAc) 2 4 H 2 O and Li Cl to form Jacobsen's catalyst. The synthesized Jacobsen's catalyst was used to catalyze the ep oxida...

  • Adamantane Boiling Point
    2,542 words
    The unique nature of diamond is heavily dependent upon its composition, crystal structure, and mechanical, thermal, and electromagnetic properties. 1 Of those dependencies, composition exacts the most influence over the characteristics. Crystal structure is the repeating pattern of diamonds composition, and each of the properties are the result of molecular interaction which is determined by composition. Therefore, composition is paramount in the determination of the qualities of diamond. Before...

  • Density Determination Melting Point And Refractive Index
    1,158 words
    Introduction This laboratory was designed to examine the physical properties of organic compounds. The three properties determined were density, melting point, and refractive index. Every compound has unique physical properties. In this laboratory the experimental results will be compared to the compounds actual cataloged properties, accuracy will then be calculated through percent error. Theoretical Basis One physical property is density. Density is the measure of mass per area volume (Density...

    Determination of Melting Points of Benzoic Acid and Benzamide and Composition Diagram of Their Mixtures PURPOSE: The purpose of this experiment is to determine the melting point of benzoic acid and benzamide and make a composition diagram for the mixtures of benzoic acid and benzamide to determine the eutectic point of the mixtures. The melting point of the given unknown will be determined using the melting point apparatus. Pure chemicals such as benzoic acid and benzamide alone have a set melti...
  • Boiling Point Impurities Water Pressure
    535 words
    Regelation is the fusion of two blocks of ice by pressure, or the "successive melting under pressure and freezing when pressure is relaxed at the interface of two blocks of ice." It is a phenomenon in which water refreezes to ice after it has been melted by pressure at a temperature below the freezing point of water. This pressure makes an ice skate form a film of water that freezes once again after the skater has passed. The effect of impurities on melting point A substance containin...
