Experiment 12: Isopentyl Acetate 19 October 2012 Introduction: The purpose of this experiment is to prepare isopentyl acetate by direct esterification of acetic acid with isopentyl alcohol. After refluxing there is an isolation procedure where excess acetic acid and remaining isopentyl alcohol are easily removed by extraction with sodium bicarbonate and water. The ester is then purified by simple distillation and the IR is then obtained. Techniques and equipment used throughout the experiment

Abstract The purpose of this experiment is to synthesize isopentyl acetate via an esterification reaction between glacial acetic acid and isopentyl alcohol‚ using concentrated sulfuric acid as a catalyst. The product was washed using sodium bicarbonate and water‚ then dried with anhydrous sodium sulfate. It was then distilled using a standard simple distillation apparatus. The percent yield of isopentyl acetate was 60.39%. This may have been low due to incomplete distillation or evaporation once

Case : Acetate Department 1) What were the objectives of the production reorganization at Acetate ? The main objective of the production reorganization at Acetate Department was to improve production capacity‚ to increase productivity. 2) Why do you think the objectives of the reorganization were not realized‚ even though no employees lost their jobs‚ and salaries were increased ? Even though no employees lost their jobs and salaries were increased‚ we can note that the productivity

The task variety was lower and the conversion process was more analyzable before the change. Before the change‚ there were more employees responsible for the actual process of taking the raw materials and creating the product. Employees had specialized tasks and the problems typically occurred less when employees had specialized tasks. The employees

Ethyl acetate (systematically‚ ethyl ethanoate‚ commonly abbreviated EtOAc or EA) is the organic compound with the formula CH3COOCH2CH3. This colorless liquid has a characteristic sweet smell (similar to pear drops) and is used in glues‚ nail polish removers‚ and cigarettes (see list of additives in cigarettes). Ethyl acetate is the ester of ethanol and acetic acid; it is manufactured on a large scale for use as a solvent. The combined annual production in 1985 of Japan‚ North America‚ and Europe

Chris CXXXX Organic Chemistry Lab Dr. Lyn XXXX 2 February 2012 Esterification of Isopentyl Alcohol to Isopentyl Acetate Procedure The technique for esterification that was employed in the experiment was to use a reflux apparatus (Figure 1) while heating in order to evaporate out water to drive our reaction into the product favored direction. The starting material of isopentyl alcohol (1.0 mL) and excess glacial acetic acid(1.5 mL‚ 17.6M) were eppendorf pipetted into a 5 mL conical vile. This

of t-Butyl-Chloride March 8 & 15‚ 2012 Theory: Alkyl halides can be synthesized when alcohols react with hydrogen halides. An alkyl halide is a halogen-substituted alkane‚ and a hydrogen halide is a compound consisting of a hydrogen bonded to a halogen (H-X). Alkyl halides are classified as primary‚ secondary‚ or tertiary depending on the number of alkyl substituents directly attached to the carbon bearing the halogen atom. The purpose of this laboratory experiment was to prepare t-butyl-chloride

Synthesis of Isopentyl Acetate Abstract The purpose of this experiment was to produce isopentyl acetate‚ banana oil. Acetic acid and isoamyl alcohol were used to synthesize isopentyl acetate. The techniques used for the separation and purification of isopentyl acetate were reflux‚ liquid-liquid extraction‚ neutralization and distillation. The identification of isopentyl acetate was based on boiling points and an infrared spectrum. This experiment resulted in a 11.68% yield. The reactants
