The combined annual production in 1985 of Japan‚ North America‚ and Europe was about 400‚000 tons.[1] In 2004‚ an estimated 1.3M tons were produced worldwide.[2] Production Ethyl acetate is synthesized in industry mainly via the classic Fischer esterification reaction of ethanol and acetic acid. This mixture converts to the ester in about 65% yield at room temperature: The reaction can be accelerated by acid catalysis and the equilibrium can be shifted to the right by removal of water. It is also

Background: Benzocaine | | C9H11NO2 | Reaction scheme for Fischer Esterification of p-aminobenzoic acid: Synthesis of Benzocaine.3 In 1890‚ a chemist named Ritsert‚ was the first to synthesis benzocaine and introduced it in the market in 1902. Benzocaine is a pain reliever and has many active over-the-counter ingredients. It is also used as a lubricant and topical anesthetic on intratracheal catheters and pharyngeal and nasal airways to obtund the pharynegeal and tracheal reflexesl.2 Sodium

Preparing Isopentyl Acetate by the Fischer Esterification Preparing Isopentyl Acetate by the Fischer Esterification Leah Monroe May 8‚ 2003 Organic Chemistry Lab II Experiment performed on April 29 and May 1‚ 2003 Abstract: The purpose of this experiment was to synthesize isopentyl acetate via an esterification reaction between acetic acid and isopentyl alcohol‚ using concentrated sulfuric acid as a catalyst. The product was washed with sodium hydrogen carbonate‚ as well as with water

Preparation of Fruit Flavors (Pear) Abstract. In this experiment an assigned Ester is prepared‚ particularly n-Propanol. The Preparation was done via Fischer reaction. In this reaction‚ a reflux set-up is required. The reflux set-up was used in the liquid-liquid extraction. After adding an immiscible solution to the compound containing n-Propanol‚ the mixture now will have two layer: the Organic and Aqueous layer. The organic layer is the extract needed and its % yield is computed resulting to

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
