  • Azo Dye Lab Report

    INTRODUCTION Dyes exist in natural and synthetic forms in the world; they are used for the purpose of changing colors of different materials. William Perkins first discovered the azo dye on accident after adding alcohol to a product in the lab. They have the ability to do this due to the molecules of the dyes possessing conjugation. Conjugation is defined as p-orbitals overlapping which causes the electrons within to be delocalized; it is also seen in molecules and compounds that contain alternating double bonds. Systems that possess conjugation absorb energy in the ultraviolet-visible region of the spectrum to cause excitement of electrons and the transitions. When the electrons get excited, they jump from lower energy levels, to an excited state; the electron that is promoted or excited, is from the HOMO, highest occupied molecular orbital to the LUMO, the lowest unoccupied molecular orbital. When conjugation increases in a system, the difference of energy between the HOMO and LUMO decreases; this signifies that higher wavelength, or lower energy light is able to make the electrons excited in the pi-system. This is when the system absorbs more waves from the electromagnetic spectrum. This in turn is relevant to the reflection of color; what color is absorbed; the complementary color will be reflected. DISCUSSION In this lab, an azo dye was to be synthesized. The dye is called “azo” because of the nitrogen-nitrogen bond that is present. More specifically, the dye is…

  • Methylcyclohexane Research Paper

    New ultraviolet (UV) curable prepolymer, 2–hydroxy–3–[p–(1–{2–hydroxy–3–(isopro– phenylcarbonyloxypropoxy) phenyl} methylcyclohexyl) phenoxy] propyl acrylate (BISCHDA) was synthesized by the reaction of p–[1–(p–hydroxyphenyl) methylcyclohexyl] phenol with methylcyclohexanone, epoxidation with epichlorohydrin followed by addition reaction with acrylic acid. All synthesized compounds were characterized by 1H-NMR, 13C-NMR and FT-IR spectroscopy. Several UV-curable formulated solutions were prepared…

  • Caprolactam And Nylon 66

    CHAPTER 1 INTRODUCTION 1.1. Introduction Caprolactam (CPL) is an organic compound with the formula (CH2)5C(O)NH. This colourless solid is a lactam or a cyclic amide of caproic acid. Caprolactam was first described in the late 1800s by Gabriel and Mass, when it was prepared by the cyclization of ε-aminocaproic acid, the product of the hydrolysis of caprolactam. In the months after Schlack’s discovery the first stocking were produced from Perlon. All the Perlon produced went to the war effort.…

  • Industrial Applications Of Citric Acid

    detergents. By chelating the metals in hard water, it lets these cleaners produce foam and work better without need for water softening. Citric acid is the active ingredient in some bathroom and kitchen cleaning solutions. A solution with a 6% concentration of citric acid will remove hard water stains from glass without scrubbing. In industry, it is used to dissolve rust from steel. Citric acid can be used in shampoo to wash out wax and coloring from the hair. (3) 3. Cosmetics, pharmaceuticals,…

  • Analysis Of Jonathan Kozol's The Human Cost Of An Illiterate Society

    The United States of America is privileged to have books to read and multiple ways to share information. Other countries have very limited or absolutely no access to information that citizens of America can easily access. Yet, the U.S. has many illiterates across the nation. It is reasonable that Jonathan Kozol places the responsibility of providing illiterates with enough knowledge and resources on the people that are literate in his article “The Human Cost of an Illiterate Society” because…

  • Wittig Reaction Of Trans-Cinnamaldehyde Lab Report

    Maci Mullins CHEM2130-001 12/8/2017 A Wittig Reaction of trans-Cinnamaldehyde Statement of Question: What is the stereochemistry in the Wittig product, and why is it formed? Hypothesis: There were two possible stereochemical outcomes for this experiment, either cis, (E,Z), or trans, (E,E). The cis product, (E,Z), would form if the double bond and phenyl group added to the same side. The trans product, E,E), would form if the double bond and phenyl group were to add to the opposite sides.…

  • Synthesis Of P-Benbenediazonium Chloride Lab Report

    Introduction: Nitrous acid (HNO2) is used as a source of nitrosonium ion (N≡O+). The nitrosonium ion by reacting with an aromatic amine converted into a diazonium salt. As diazonium ion is a weak electrophile, it reacts with electron-rich, aromatic coupling agents to produce an azo dye. The products are mainly ortho and para due to the reaction being an electrophilic aromatic substitution Reaction: p-nitroaniline p-nitro benzenediazonium chloride Para-red…
