As you first read the Banana Time case you might be asking yourself‚ “what do I do with this case? There are no questions at the end to which I can simply respond”. Attempting to analyze a social system or group such as described in the Banana Time case can be an awkward‚ chaotic experience‚ especially at first. Start with your primary task which is to 1) identify each of the social system elements (as listed in bullet points below and on page 83) and 2) to see if you can describe the interaction

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

Preparation of Synthetic Banana Oil Introduction: In this lab the synthesis‚ purification‚ and characterization of isoamyl acetate‚ or banana oil‚ was determined. The synthesis was completed by a reversible esterification reaction which required the heating of glacial acetic acid and isoamyl alcohol‚ combined with a sulfuric acid catalyst in hexane. In order to increase the efficiency of the reaction‚ LeChatelier’s Principle is utilized by removing water from the products. As a result‚ the reaction

aMicroscale Synthesis of Isopentyl Acetate (Banana Oil) Objective: Carried out the microscale synthesis of isopentyl acetate by direct esterification of acetic acid and isopentyl alcohol. This was an acid catalyzed Fischer esterification. Both extraction and distillation were employed to obtain a pure product. IR spectroscopy and gas chromatography were used to determine purity of the final product. Reagents: * Compound: | * MW (g/mol): | * MP (°C): | * BP (°C): | * Density (g/mL):

BERGERAC CASE STUDY Summary The purpose of this report is to analyze the opportunity to produce plastic components for cartridge production and choose the best alternative. It is predicted that the annual demand growth is a triangular distribution with a minimum of 5%‚ most likely of 17% and a maximum of 25%. Due to the continuous growth in the demand‚ the alternatives cannot be compared using just the data for 2010. An analysis is carried out for the time period 2011 to 2015 and the present worth
