Ethanol : Formula, Structure And Uses Of Ethanol

Ethyl ethanoate: Ethyl ethanoate is an ester. Esters are group of organic compounds which have a functional group of –COO-. Esters are liquids that become vapours quickly so they are present in perfumes.

Generally ethanol is an alcohol found in alcoholic drinks. At 100% concentration, it is pure and a colourless liquid with a strong odour (due to weak Van der Wall forces :D. Ethanol is produced by the fermentation of carbohydrates in yeast cells and is used frequently as a solvent.

In the United States of America, corn ethanol is the main raw material we use to move our vehicles to accomplish our daily goals. Obviously, corn ethanol is presenting ethanol by corn. The biomass in the ethanol adds fermentation, a system that breaks down any chemicals or other substance in any liquid. Additionally, it is added distillation, the action of purifying the process of heating and cooling. This is how corn ethanol is made.

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.

According to Oxford Dictionaries, alcohol is a colorless volatile flammable liquid that is produced by the natural fermentation of sugars and is the intoxicating constituent of wine, beer, spirits, and other drinks, and is also used as an industrial solvent and as fuel (Fowler, H. W., Fowler, F. G., & Murray, J. A. (1964). The concise Oxford dictionary f

Ethanol (CH3CH2OH) is a clear, colorless liquid. It is also known as ethyl alcohol, EtOH, and grain alcohol. Ethanol is widely produced by processing grains such as corn or starch and sugar crops. The grain is first milled, then fermented with yeast and different enzymes to turn the grain 's starches into alcohol(EPA). A distillation process then increases the ethanol concentrations, basically the same process a whiskey maker would use to make whiskey. Of course, law mandates that a denaturant is added, making the liquid unsafe for drinking. In the process, waste grain is produced and sold as farm animal feed. Bioethanol, can be made from many types of trees and grasses, but the procedure is much harder. The chemical formula of ethanol is the same whether it is made from starch and sugar-based feedstocks, such as corn grain (widely used in United States), sugar cane (Brazil), or from cellulosic feedstocks (such as wood chips or crop residues).

Alcohol- any organic compound in which the hydroxyl functional is bound to a saturated carbon atom. Excessive amounts of alcohol can lead to intoxication leaving you mentally and physically impaired. It could also slow your reaction time to a very low speed and lead to malnutrition. Alcohol poisoning is a dangerous condition that results when a person decides to drink more alcohol than their body can comprehend. Alcohol is a depressants. Depressants are drugs that slow down the body's functions and reactions.

I can narrow down my unknown substance to either Ethanol or 2-proponal. Ethanol’s density is only 0.001g/mL higher than my own measurements, but its boiling point is 8.4̊C lower than GNR’s. Whereas 2-proponal’s density is off by 0.003g/mL and its boiling point is only off by 4.5̊C. If I were to make an educated guess I would lean more towards Ethanol. Both the precision and accuracy of my data was far greater in density than in boiling point and Ethanol’s density is closer to GNR’s than any other substance.

Methanol is the simplest alcohol (one carbon backbone). It is a clear, colorless liquid with a characteristics alcohol odor.

Ethanol, also called ethyl alcohol or drinking alcohol, is an organic compound belonging to the alcohol group. It could also be abbreviated EtOH. The hydroxyl, OH, functional group differentiates the compound from the other organic compounds and hence shares some of the same physical and chemical properties, with other alcohols. Ethanol is used as fuel, solvents and in alcoholic beverages. It is also used as antiseptics, household cleaning products, varnishes and in alcohol thermometers (Garcia). The molecular formula of ethanol is C2H6O, normally written as C2H5OH or CH3CH2OH. The molar mass, boiling point and melting point of ethanol is 46.069g/mol, 78.29ºC and -114.14ºC, respectively (Ethanol). Ethanol is a colorless liquid with a slight odor, soluble in water, flammable, volatile and evaporates easily when left in the open (Garcia).

Ethanol fuel is typically just made from plant biomass by pretreatment, fermentation, and distillation, which is very much the same way that beer and liquors are produced.

i. Ethanol is considered as a alternative fuel at a lower cost level in relation to gasoline. It is produced by fermenting sugars from a range of feedstock such as wheat and corn. Ethanol is blended with gasoline from E10 (5% ethanol - 95% gasoline) to E85 (85% ethanol - 15% gasoline).

As we all know, alcohol is a product that has provided a variety of functions for people in the world. Alcoholic beverages have been consumed by humans in the very early time, they were one of the most popular drink and have been widely used in everywhere of the world. Also they were used medicinally, chemically, physically and so on.

This essay will first discuss the advantages of using corn ethanol as the main source of fuel in the future, such as the renewable features of corn itself, and the benefits of using corn ethanol as an additive of gasoline instead of using gasoline alone. However, everything has its strengths and weaknesses. Therefore, the second part of the essay will discuss some of the weaknesses in applying the fuel into practical usage. For example, corn ethanol currently encounters technical limitations serving itself as a standalone fuel, meaning that corn ethanol can only function by combining itself with a certain amount of gasoline, while gasoline is a kind of fossil fuel. Lastly, this essay will conduct a comparison with other renewable resources in the world, including solar power, other biofuels, and hydrogen fuel.

Alcohol dependence (alcoholism), occurs when the body cannot function without the effect of alcohol. Alcohol affects specific neurotransmitters in the brain and when the brain becomes accustomed to the alcohols affects it can no longer function properly signals without the help of the alcohol. Once someone has developed a dependency on alcohol, they will continue to drink regardless of any serious physical complications that are caused by alcohol.
