Fischer Esterification Kyle Peterson Chem. 243a Matt Judd‚ Sec. 25 Date Performed: 10/15/03 Abstract: The objective of this experiment is to efficiently perform a fischer esterification of 1-Hexanol to form water and hexyl acetate‚ and to confirm the esterification with a nuclear magnetic resonance (NMR) spectroscopy. It was found that 0.3963 grams hexyl acetate was formed with a percent yield of 33.2%. The product was confirmed using NMR‚ IR‚ and boiling point confirmation. Backround: A Fischer

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

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

synthesize methyl benzoate form benzoic acid and methanol by using the Fischer esterification method. The Fischer exterification technique is utilized in the academic and industrial settings due to the simplified synthesis and safety parameters of the overall reaction. Both benzoic acid and methanol are relatively cheap to obtain from a commercial source as well as being easy to store with a relatively long shelf life. The Fischer esterification method is a fundamental and important synthesis process in training
