Experiment #1 Preparation of Ethanol from Sucrose Based on R. Weglein & C.L> Yau‚ CHEM 203 Experiments in Organic Chemistry II Laboratory‚ 5th Edition‚ 2006‚ p29-32. Statement of Purpose: An aqueous solution of ethanol is prepared by the fermentation of sucrose. The percent alcohol is the resulting solution and the percent conversions of the sucrose are to be determined. Introduction: Sucrose is a molecule containing glucose and fructose. http://faculty.tcc.fl.edu/scma/phelpsj/experiments/ethanol

Ethanol Ethanol is easily soluble in water in all proportions with a slight overall decrease in volume when the two are mixed. Absolute ethanol and 95% ethanol are themselves good solvents‚ somewhat less polar than water and used in perfumes‚ paints and tinctures. Other proportions of ethanol with water or other solvents can also be used as a solvent. Alcoholic drinks have a large variety of tastes because various flavor compounds are dissolved during brewing. When ethanol is produced as a mixing

Extraction of Bio-ethanol from Apple (Malus domesticus) and Banana (Musa accuminata Colla) Peelings through the Process of Fermentation and Distillation Abstract Apple (Malus domesticus) and banana (Musa accuminata Colla) peelings are common household waste products. This study sought to extract bioethanol from these two peelings and to compare which sample can produce more bioethanol. About 400 grams of apple and banana peeling was obtained from the 1 kilogram bought from the supermarket and

OVER PRODUCTION Overproduction is producing more or faster than the required demand or speed. It usually starts by getting ahead of the work required. Overproduction is mainly occurred when; Tact time>Cycle time Tact time=(time available)/(customer demand) When the cycle time which is the time taken by the production line to create a unit of product is very much smaller than the tact time‚ the time which is expected to be taken by the production line to meet the demand‚ overproduction is occurred

According to a report by MOEF (Ministry of Environment and Forests)‚ e-waste from old computers and mobile phones would jump by 500% and 1800% as compared to 2007 levels by 2020 in India. But before that‚ let us understand what exactly e-waste is‚ what are its implications and how companies are trying to curb this by using Green IT. Scenario of e-waste in India: Electronic waste (E-waste) in simple terms‚ refer to the discarded electronic devices. E-waste includes waste generated

Ethanol What is Ethanol? Ethanol‚ which is sometimes called ethyl alcohol‚ pure alcohol‚ or grain alcohol is defined as‚ “a high octane‚ clean burning‚ American- made renewable fuels.” Ethanol is an increasing important aspect of our society and its popularity is becoming more widespread on a daily basis. Ethanol‚ a substance made out of Sugar-cane‚ maize‚ sorghum‚ wheat ‚ and other grains‚ has become one of the main viable source of energy in the world. In countries like South

carbohydrate for fuel ethanol production (Comis‚ 2008). Ethanol production from fresh cassava roots using a low-temperature process was evaluated on a pilot-plant scale. The application of low-temperature cooking to cassava starch followed by a dual enzyme action resulted in an ethanol yield comparable to that of a traditional high-temperature cooking process. Pressurized distillation gave a satisfactory recovery efficiency of ethanol but was slightly lower than that obtained from atmospheric pressure

Carbohydrate: Ethanol from Sucrose Abstract The purpose of this lab was to demonstrate the fermentation process of ethanol from the substrate sucrose. To make ethanol from sucrose two enzymes invertase and zymase were used. Vacuum filtration and fractional distillation were performed to get a more concentrated solution. The density of ethanol was .825 g/mL with a percent composition of 85% pure ethanol. Introduction

If any of these nations fail to supply the U.S. because of a terror attack or bad relations‚ the economy would be negatively impacted. How can the U.S. reduce dependence on imported fuels and diversify our energy supply? In recent months‚ the new focus is the investment in research and development of alternative or renewable energy.
