oily‚ and it had a banana smell. Introduction Artificial flavoring is commonly used in the food that we eat today. For example‚ fruit flavoring is a chemical mixture that mimics a natural flavor as that of banana flavor from the synthesis of isoamyl acetate. Ester is the functional group‚ which is responsible for the distinctive odor and taste that artificial fruit flavoring has. Esters are derived from carboxylic acids. A carboxylic acid contains the –COOH group‚ and in an ester the hydrogen in

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

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

ACETATE DEPARTMENT 1. Analyze the Acetate Department’s technology‚ before and after the change‚ by identifying its task variety and analyzability. 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

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

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

Preparation of an Acetic Acid Ester Abstract: 14.1 g of octyl acetate were synthesized from the esterification process using 20.0 ml of acetic acid and 17.9 g of n-octanol. The theoretical yield was 23.8 g of octyl acetate. The percent yield was 59.2%. The purification of the final ester was confirmed by boiling point (186-199°C) and infrared index (nD=1.419). It was a colorless liquid that had a slight fragrance of orange and indescribable chemicals. The Infrared spectra confirmed ester

------------------------------------------------- How to make own Sodium Acetate ------------------------------------------------- 1. Add 6 tablespoons of baking soda to a pot. Do not use baking powder. 2. Add 2 liters of white vinegar to the baking soda until it stops fizzing. Do this bit by bit to avoid spills and stir often. When the fizzing stops‚ the reaction is complete‚ leaving you a diluted solution of sodium acetate. The solution should be clear. 3. Boil the solution until around
