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…

MYCOCEPT (Mycophenolate mofetil) is the 2-morholinoethyl ester of mycophenolic acid (MPA). CHEMICAL NAME: 2-morpholin-4-ylethyl (E)-6- (4-hydroxy-6-methoxy-7-methyl-3-oxo-1H-2-benzofuran-5-yl)-4-methylhex-4 enoate. STRUCTURAL FORMULA: Fig: Mycophenolate mofetil MOLECULAR WEIGHT: 433.50g/mol APPEARANCE: Mycophenolate mofetil, is a white to off-white crystalline powder. SOLUBILITY: It is slightly…

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…

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.…

Organic Acids An organic acid is an organic compound with acidic properties. The most common organic acids are the carboxylic acids, whose acidity is associated with their carboxyl group –COOH. Sulfonic acids, containing the group –SO2OH, are relatively stronger acids. Alcohols, with –OH, can act as acids but they are usually very weak. In general, organic acids are weak acids and do not dissociate completely in water, whereas the strong mineral acids do. Lower molecular mass organic acids such…

Benzene, rings are very prevalent in many products that are used on a daily biases by humans, and compounds that contain benzene are often referred to as being aromatic. Benzene has characteristics that differ from many compounds causing it to react differently when mixed with certain compounds. Although benzene has three double bonds, it does not react like a normal alkene in terms of addition reactions. For example, when bromine reacts with a simple carbon-carbon double bond it forms dibromo.…

Additionally, it states that nearly one half (41 to 44 percent) of adults in the US that have a minimal level of literacy perform in low skill jobs.With this knowledge, how well would a person with a minimal, if nonexistent education, perform on a simple functional literacy test? This lack of literacy then leads to the conclusion that it creates a gap-most of those who are literate can hold more or less stable jobs with a medium high salary,…

compounds classified as derivatives of oxoacids and alcohols (IUPAC,1997), however for the purpose of this formal report, esters refer to derivatives of carboxylic acids or carboxylic acid esters. (Gunawardena, 2009) Esters have closely identical functional groups with carboxylic acids which include an acyl group bonded to an oxygen which is bonded to another molecule the only difference is that carboxylic acids are bonded to hydrogen atoms (acyl group bonded to an –OH) while esters are bonded…

to the functional groups in 6-ethoxycarbonyl-3,5-diphenyl-2-cyclohexenone. These functional groups are sp2 hybridized carbons at 3031 cm-1, sp3 hybridized carbons at 2981 cm-1, a carbonyl at 1735 cm-1, aromatic carbon-carbon stretching at 1660 cm-1, an ester carbon-oxygen stretching at 1144 cm-1, and alkene carbon-hydrogen stretching at 698 cm-1. There was no alcohol present in this spectra, indication that all of the catalyst was removed successfully. Also the presence of alkene functional…

Literacy: Lifelong learning Literacy as we know today is a basic fundamental human right and is the foundation for a lifelong learning experience. Literacy is more than just the ability to read and write, but it is more on the side of being able to comprehend what you are mainly reading and writing. For someone who cannot read nor write is called an illiterate person, and what illiteracy means is not having the ability to read or write. But with literacy, I feel like it gives me more confidence,…
