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...

Ethanol: Good or Bad? In the pursuit of a cleaner renewable resource to fossil fuels, many scientist have found alternatives. Examples include solar, wind, biogas, geothermal, biomass energy and cellulosic ethanol. In the last twenty years, efforts have been made to reduce our dependency on foreign oil and ethanol has been an option. Ethanol is nothing new; in fact, it was first used in a motor built by Samuel Morey in 1826 (Ethanol History). Since the 1980s, the government started having oil companies...

Production of Ethanol

Introduction Ethanol most commonly which is produced through the fermentation of glucose by yeast cells. Fermentation is an energy-yielding process that cells carry out in the absence of oxygen. Although fermentation does not provide much usable energy for the cell, it is sufficient for yeast cells. Yeast cells produce ethanol and CO 2 as byproducts, and the ethanol produced valuable energy source. There is much interest in ethanol as an energy alternative which are nonrenewable and contribute significantly...

Ethanol Production

Ethanol Production Ethanol is the type of alcohol found in alcoholic drinks such as wine and beer. Its chemical formula is: C2H5OH. Glucose from plant material is converted into ethanol and carbon dioxide by fermentation. The enzymes found in yeast (single-celled fungi) are the natural catalysts that can make this process happen. Here is the word equation: Sugar → Ethanol + Carbon Dioxide ...

Brine Shrimp and Ethanol Alcohol

The Effect of Ethanol on the Viability of Artemia salina as Environmental Indicators Biology 151 Laboratory ABSTRACT Artemia salina are used as environmental indicator species. They are used to test changes in their environment. A. salina is sensitive to toxins, temperature, and drugs. For the experiment, cysts were put into different amounts of ethanol alcohol and their viability was measured. The hypothesis used was if there is more ethanol alcohol, then the viability...

Ethanol, a Fuel

Ethanol, a Fuel? Ethanol fuel is a type of alcohol found in alcoholic beverages that is often made from common agricultural products. It is either mass-produced by fermentation of sugars or from cellulose. Wheat or corn kernels are ground in a hammer-mill to expose the starch, the ground grain is then mixed with water, heated briefly and enzymes are added to convert the starch to sugar using a chemical reaction called hydrolysis. Yeast is added to ferment the sugars to ethanol and finally the...

Preparation of Ethanol from Sucrose

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...

Cassava as ethanol

three times as much 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...

Analysis of Ethanol in Moonshine

Analysis of Ethanol in Moonshine | Using the GC-MS | Jennifer Greene | ------------------------------------------------- 4 May 2012 ------------------------------------------------- 4 May 2012 Introduction: In this experiment gas chromatography is applied to separate the water-ethanol mixture. This method is often used in the determination of alcohol in blood or urine. One obvious application is when law enforcement agencies need to determine whether or not someone is inebriated...
