In this activity you will find out why ethanol is an important chemical. You will study three ways of making industrial ethanol. Then decide which of the methods is ‘greenest’, or most sustainable, in the UK.…
We began with 16.2 mL of isopentyl alcohol and continued through the processes of reaction, separation, and purification until a final product was achieved. There were two peak areas appearing on the gas chromatogram, isopentyl alcohol and isopentyl acetate. The area of isopentyl alcohol (2) is 0.255cm2 where the area of the isopentyl acetate (1) is 8.4cm2. This results in the percentage of isopentyl alcohol (3) in the final product being 3% and the percentage of isopentyl acetate (4) 97%. The percent yield (5)of isopentyl acetate is also 97%.…
Ethanol is commercially produced using a process called fermentation. Many other alcohol can be made this ways, but are more likely to be produced by synthetic routes from natural gas, oil or coal.…

Alcohols are a common substance found in everyday life. From petrol to spirits, alcohols are a substantial product used in normal everyday life. Alcohols range from a percent chain starting at one and commonly ending at twelve. Alcohols are named after the number of (OH) hydroxyl groups within them, Methanol being one, Ethanol containing two carbons and so on. For this experiment the alcohols used were Methanol,…
Instead of collecting the 10mL of distillate required, 7.8mL of distillate was obtained. The density determined was .825g/mL, when compared to the graph provided by the instructor the ethanol produced had an 85% final product. According to the graph the results were somewhat accurate, even through the ethanol produced did not have 100% it still fell within the desirable percentile.…
Ethanol is definition of stability; a fuel that decreases oil imports, is clean burning, and contributes useful byproducts. Ethanol is definitely part of the solution.KAAPA Ethanol, established in November of 2003, has created many new opportunities and jobs for the industry. Scott McPheeters and Shana Dahlgren gave an enthralling presentation of how ethanol system works and the benefits of the country’s adoption of ethanol and its byproducts. Video presentations were able to captivate the audience’s attention while it presented facts about the…

The goal implemented for Richard was to reduce his off-task behavior to increase his performance on classroom assignments. According to Tarbox, Ghezzi, and Wilson (2006), the implementation of the token board has demonstrated as an effective method when there is a reinforcement. Implementing a reinforcement with the token board increases student motivation to eliminate the target behavior (pp. 162-163). When implementing the token board with Richard, reinforcements were selected. The reinforcement were based on student preference of interest based on interview with student.…
Ethanol is one of the oldest alcohols and also the least toxic one. Industrially, ethanol is made most economically by hydration of ethylene. However, ethanol that is intended for human consumption must, by law, be prepared by fermentation. By either method, ethanol, of course, has the same formula, structure, and properties. The fermentation takes place with the assistance of enzymes from yeast in 2 steps: first sucrose (a disaccharide whose structure is in your textbook) is broken down to two monosaccharides, glucose and fructose. These monosaccharides are then converted into ethanol and carbon dioxide.…
Instead of growing corn based ethanol, which causes negative effects to our economy and to the environment, researchers have discovered a new product, "cellulosic ethanol." Cellulosic ethanol is formed from waste plant material (cellulose) through a process called “thermo-chemical conversion”. Cellulosic ethanol plants are underway and the future of ethanol energy is making huge advancements. Unlike corn based ethanol, cellulosic ethanol will be less harmful to the environment and more economically…
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 ethanol is separated from the mixture by distillation. The fermentation process is quite simple; a glucose molecule is broken down into ethanol molecules and one carbon dioxide molecule, the carbon dioxide is released into the air and you are left with a colourless, clean burning liquid with a strong odour. This makes it easy to produce an alternate cleaner burning fuel for cars and other means of transportation. Ethanol is already being used in high-performance motor fuel because it cuts poisonous emissions and is better for the environment then traditional fuels. There have been many developments in using a higher ethanol concentration in fuels for cars and other types of transportation, by many leading car companies research institutes. New engines have been developed called Flexifuel, these engines are able to burn a E85 fuel opposed to the traditional motor fuel with an ethanol concentration at most of 10%, this makes the E85 fuel less expensive and cleaner burning. The Canadian government and some provinces have continuously supported the product of ethanol fuel and the use of it, any ethanol blended fuel receives exemption from the federal tax of 10 cents a litre for gasoline. As reaction to the Government of Canada Action Plan 2000 on Climate Change, the government of Canada establish the Future Fuels initiative to increase the supply and use of ethanol produced from biomass. There is three main components to this initiative that the Canadian Government has…

Alcoholic beverages are the only consumable products in the U.S. that do not have nutrition labels. Consumers are being kept in the dark about serving size, alcoholic content, calories, carbohydrates, fats, protein, cholesterol and other nutrition information. Alcohol, specifically ethyl alcohol or ethanol, is produced by fermenting the starch or sugar in various fruits and grains. Alcoholic beverages produced by fermentation and distillation include beer that is usually about 4 to 6 % alcohol, wine that is usually 7 to 15% alcohol, and hard liquor which is about 45% alcohol.…
Ethanol is made by mixing yeast with plant material and kept warm. Yeast is a unicellular organism whose diet is made of plant material. Sugars are turned into alcohol by the yeast. This process, used in producing ethanol, is called fermentation. Primarily corn is used to produce ethanol in the United States. Ethanol creates less polluting gases than gasoline or diesel. Mixing gasoline and ethanol can help decrease pollution. Brazil is the world’s largest ethanol producer (Solway 12). Ethanol is produced from sugarcane in Brazil. The sugarcane is crushed to extract the sugar. Then the sugar is dissolved. Vehicles in Brazil run on a higher concentration of ethanol than vehicles in the United States. The remnants of the sugarcane is referred to as bagasse. Dried bagasse can also be used as fuel (Solway 13). Power plants may burn bagasse to produce electricity. Sugarcane can produce the power needed to keep the ethanol plant running and the sugar to make ethanol.…
