Conversions of Alcohols to Alkyl Halides: 1-Propanol and 2-Pentanol Introduction One way scientist gets alkyl halides is by using the manipulation of an alcohol. When alcohols are treated with HBr or HCl; they can undergo a nucleophile substation reaction to generate an alkyl halide and water2. Using the structure of the alcohols they are able to use SN1 or SN2 mechanisms. For both these mechanisms though, the –OH group must be pronated shown in Figure 1. R—OH + H—Br + R—OH2 +Br- Figure

Synthesis of esters: In this study, triester derivative (5) was synthesized through a two-step reaction of monoepoxidation and opening of oxirane ring to synthesise the monoester 9,(12)-hydroxy-10,(13)-oleioxyoctadecanoic acid (HYOODA) (3). MELA (2) results in a mixture of two monoepoxides (cis-9, 10-epoxy 12c- 18:1 (2a) and cis-12, 13 epoxy 9c- 18:1(2b)) with yield% of 82.14, while the oxirane ring opening in the presence of p-toluene sulfonic acid (PTSA) to prepare 9,(12)-hydroxy-10,(13)-oleioxyoctadecanoic

Introduction The history of polymers stretch back millions of years. These “primitive” polymers were created by nature to fulfill the needs of information storage, energy storage and information reproduction. Human made polymers are a more recent invention, of the last two hundred years or so. These polymers are general made of highly flammable hydrocarbons and their derivatives. Fires caused by a combination of human careless and the physical properties of hydrocarbons have caused millions of dollars

composition of gasoline depends on the refinery processes, the crude oil used, the overall balance of product demand, and the especially the product specifications. The typical composition of gasoline hydrocarbons (% volume) is: 4-8% alkanes; 2-5% alkenes; 25-40% isoalkanes; 3-7% cycloalkanes; l-4% cycloalkenes; and 20-50% total aromatics (0.5-2.5% benzene). Table 1 shows

Fundamental Structures and Properties of Teflon and Its Applications in Industry 1. Introduction Polytetrafluoroethylene (PTFE) also known as Teflon is a thermoplastic polymer. It is formed by addition polymerization using the monomer tetrafluroethylene (TFE). Teflon is a strong, waxy and non-flammable resin which is used in many applications especially in corrosive industries due to its resistance to chemicals. In addition, it is able to maintain its physical properties over a wide range of

VOCs are more complex hydrocarbons than CH4 that are emitted from biogenic and anthropogenic sources. Biogenic VOCs include alkanes, alkenes, alcohols, aldehydes, etc. Generally, anthropogenic VOCs are diverse and also include aromatic hydrocarbons, most importantly benzene, toluene, ethylene and the isomers of xylene as major components (up to 75%).5 To say the least, there is a wide

Experiment 3: Oxidation of Borneol to Camphor By: Evan Holley Lab partner: Jeffrey Horton T.A.: Garret CHM2211L-008 07/12/2015 Introduction The overall goal in this lab was to oxidize borneol, a secondary alcohol, into camphor, which is a ketone. For the purposes of oxidation chromic acid was utilized, which was prepared by adding a 1:1 ratio of chromium trioxide to dilute sulfuric acid. The oxidation reaction occurs as a two-step reaction. The first step involves the formation of

Experiment 5 Title : Thin Layer Chromatography Objectives: i. To distinguish polar and non-polar solvents. ii. To familiar with the analysis technique by using the thin layer chromatography. iii. To differentiate the retention factor, Rf for different compounds. [pic] Result: |Compound |Distance traveled by the compound | |o-nitroanaline |2.45

EXTRACTION OF CAFFEINE FROM TEA Abstract The method used to separate the organic compound from a mixture of compound is the extraction. It is done by the dissolving of one or more compounds in a good solvent. The solvent which was used in this experiment was 15 ml of dichloromethane into 125ml of water. Caffeine was extracted from 9.19 g of TAZO Awake English Breakfast. Caffeine is soluble in water in 2.2 g/ml at 20 C; it is more soluble than dichloromethane which has 10.2g/ml at 20 C, and the
