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

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

Preparation of Esters Introduction Esters are known for their pleasant smells such as perfumes and artificial flavorings in contained labs. They are formed when a carboxylic acid reacts with alcohol and a strong acid such as a catalyst called sulfuric acid (H2SO4) for this lab. The structural formula for esters can be represented as R-COO-R’. The R and R’ symbolizes different alkyl groups that can be combined to the ester. When naming an ester the first part comes from the alcohol followed

Lab 5: Preparation of Synthetic Banana Oil September 20th‚ 2012 Purpose: The main purpose of this experiment was to synthesize banana oil (isopentyl acetate.) Ester are often prepared by the Fischer esterification method‚ which involves heating a carboxylic acid with an alcohol in the presence of an acid catalyst. Theory: Synthesize isopentyl acetate by combining isopentyl alcohol with acetic acid and sulfuric acid and then heating the reaction mixture under reflux for an hour. The alcohol

Synthesis The old acetate department located in an old four storey building follows a workflow that is heavily based on shifts/rotations because production is based on a per batch basis. A typical shift‚ the group leader and his crew would complete two or three batches. The night shift usually has lesser work because no deliveries were made. In the new system‚ the management wants to improve productivity. The department was redesigned from batches to continuous processing. Technical changes

Undoped and Ce doped ZnO thin films were prepared by the sol-gel process. Zinc acetate dehydrate was dissolved in a mixture of absolute ethanol and monoethanolamine (MEA) yielding to a precursor concentration of 0.4 M .The MEA to zinc acetate molar ratio was set to 1. For doped films‚ cerium nitrate was added to the mixture with an atomic percentage fixed at 0.1‚ 0.3‚ 0.5‚ 0.7‚ and 0.9 at.% Ce‚ respectively. The resulting sols were magnetically stirred at 60°C for 1 hour and then aged at room temperature
