    Mika C. Trino‚ Jahn Camille B. Valdez‚ Ariza Yamashita Department of Biological Sciences‚ College of Science Group 11 Corresponding author: gerome_911@yahoo.com Abstract The purpose of this experiment was to synthesize isopentyl acetate via Fischer esterification reaction between acetic anhydride and isoamyl alcohol‚ using concentrated sulfuric acid as a catalyst. This reaction is characterized by the combining of an alcohol and an acid (with an acid catalyst) to yield and ester plus water. In order

    it can be classified by Fischer esterification. Fischer esterification reactions typically include a carboxylic acid and alcohol as well as a dehydrating agent . Since esterification reactions are slow‚ a catalyst is required. The addition of the catalyst maximizes the yield of product (benzocaine) from the esterification since the reaction is reversible which means it tends to result in a low yield of product. For the synthesis of the benzocaine in this experiment‚ Fischer

    Synthesis of Isopentyl Acetate (Banana Oil) Using A Fischer Esterification Reaction Purpose: The purpose of this experiment is to synthesize Isopentyl Acetate using a Fischer esterification reaction. Fischer esterification is an acid-catalyzed condensation of an alcohol and a carboxylic acid‚ yielding an ester and water. Isopentyl Acetate has the scent of banana oil‚ once synthesized it will be purified by distillation. Then the analysis of the sample using H NMR and IR will determine purity

    Abstract: For the first part of this lab we refluxed different Carboxylic acids and alcohols in the presence of a acid catalyst in order to form Esters by Fischer Esterification. These Esters had different pleasant smells that we then evaluated. In the second part of the experiment‚ we broke the ester bonds of a triglyceride in order to form glycerol and carboxylate salts. This process is known as Saponification because it produces amphiphilic molecules that allow soap to remove dirt from the surface

    Abstract Fisher Reaction is a special type of esterification that uses an acid catalyst to reflux Carboxylic acid and Alcohol. The product Ester is in equilibrium to the reactants acid and alcohol. Ester is responsible for the smell and aroma of different fruits. After using the Fisher reaction‚ a combination of techniques is used to separate the product. Introduction Esters are naturally occurring compounds that possess a distinctive odor. It is responsible for the smell of different fruits

    Synthesis of Isopentyl Acetate Abstract Isopentyl acetate was synthesized via a Fischer Esterification and purified via simple distillation. The yield was determined to be 25%. The identity and purity of the product was confirmed by comparison of the measured ultra-micro boiling point (140°C) to the published value (142°C).1 Chemical Equation Procedure Isopentyl alcohol (0.787 g‚ 1.2 mL‚ 8.93 mmol)‚ acetic acid (1.574 g‚ 1.5 mL‚ 26.20 mmol)‚ and sulfuric acid (0.368
