Synthesis of Isopentyl Acetate (Banana Oil) Using a Fischer Esterification Reaction Zhenshu Wang (Stan) TA: Aaron League September 23‚ 2012 Purpose: The purpose of the experiment was to perform the acid-catalyzed Fischer Esterification of acetic acid and isopentyl alcohol to form isopentyl acetate‚ or banana oil‚ which is used in flavor industries. The equilibrium of the reaction was changed by adding an excess amount of acetic acid. The reaction was refluxed and product was purified by extraction

iodine will be added to a test tube using a dropper in lieu of a graduated cylinder. Appearance of solution will be recorded. Then‚ 1mL of hexane will be added to the test tube mix. Observations of both layers will be recorded. Process repeated for bromine. For the third solubility test‚ 1mL of hexane will be added to a clean test tube. Then‚ 0.5mL of Clorox and 0.5M HCl (to make chlorine) are added. The color of each layer is noted. Part III: Electronegativity Testing This set of reactions

and Applied Chemistry (IUPAC) General Form of IUPAC Nomenclature [branching substituent(s)] Root [Suffix] Rules: 1. Identify the longest continuous chain of carbon atoms. This chain determines the parent name (root) of the alkane. The parent suffix for alkanes is‚ not surprisingly‚ -ane. For chains of equal length‚ pick the one with the most substituents. (Note: I number all possibilities going from left to right – identify the longest chain) 2. Number the chain beginning at the

Abstract 1‚2-dibromo-1‚2-diphenylethane was produced by the bromination of trans-stilbene through the addition of hydrobromic acid (HBr) and hydrogen peroxide (H2O2). This experiment was a greener bromination of stilbene because bromine was generated in situ and ethanol was used as the solvent. The melting point (243.30°C)‚ mass (.427g)‚ and percent yield (45.54) of the crystals were recorded. The FTIR was used to confirm that the product was produced. The peaks on the HNMR revealed

BROMINATION OF ACETANILIDE OBJECTIVE Aim of the experiment was too brominate acetaldehyde to form p-bromoacetanilide. INTRODUCTION Acetanilide is a chemical compound with the chemical formula of C6H5NH(COCH3). It is a crystalline solid that is prepared by acetylation of analine and is widely used in the dye industry. This crystalline solid is an odourless solid chemical that has a flake or leaf like appearance. It is also known as N phenylacetamide‚ acetanil or acetanilide. Its former
