Ethanol is a volatile, flammable, colourless liquid. It is the principal type of alcohol that found in alcoholic beverages produced by fermentation of sugars by yeast. It is used as an antiseptic, a solvent, a fuel. Due to its low freezing point,active fluid in post mercury thermometers (Nivedita, 1998).Ethanol, the renewable resource, produced from fermentation of glucose rich substrates, like sugar cane, fruit juices, tapioca, sweet potatoes, sweet sorghum etc. Starchy materials like maize, wheat
Ethanol Proposal Purpose As the number toxin spewing cars rises, pollution has presented itself as a major problem in urban areas. There have been many solutions presented to help solve this problem, but few have been widely accepted by the general public. I believe the pollution problem is one that cannot be solved in one big step, but in smaller steps. I see Ethanol use as one of those steps. The intention of this proposal is to recommend an approach that would lead to widespread use of
The Oxidation of Ethanol Ethanol is a primary alcohol and can be oxidized to either an alderhyde or a carboxylic acid. [IMAGE]CH3CH2OH + [O] CH3CHO + H2O [IMAGE]CH3CH2OH + 2[O] CH3COOH + H2O The purpose of this experiment is to oxidize ethanol and then to test the product to determine whether it has been oxidised to ethanal or oxidised to ethanoic acid. Method We added 6cm³ of water to a pear-shaped flask, then added 2cm³ of concentrated sulphuric acid, and set up the apparatus
Missing Figures Ethanol Abstract: As of now we drive cars almost everywhere from home to the local store or different states. According to www.wikipedia.com there is “an estimated 243,023,485 registered passenger vehicles in the United States according to a 2004 DOT study!” 1That is a lot of cars. In a year the US alone consumes around 146 billion gallons of gasoline that is a huge amount. 2 According to figure 1 about 86% of all world energy comes from oil, gasoline, and coal; this leaves
off the dependence on fossil fuels. One of the best alternative energy sources is ethanol. Ethanol is a renewable energy source as it uses sunlight, which will last almost forever, as a part of its production process. Ethanol is also an environmental-friendly energy source because it helps in reducing smog pollution and carbon dioxide emissions by up to 50%. This makes ethanol a perfect alternative energy source. Ethanol can act as a raw material for polymers such as polyethylene through the dehydration
Ethanol fermented from renewable sources for fuel or fuel additives are known as bio-ethanol. Additionally, the ethanol from biomass-based waste materials is considered as bio-ethanol. Currently, there is a growing interest for ecologically sustainable bio-fuels. The target in the European Union is to increase bio-energy contributions in total energy consumption from 3 to 11 % by the year 209. Ethanol is a fossil fuel which is made from sugars found in plants. In the India, it is usually made from
Preparation of Ethanol and Ethanoic Acid AIM: To obtain pure samples of Ethanol (CH3CH2OH) and Ethanoic Acid (CH3COOH) from fermented Yeast (Saccharomyces Cerevisiae). BACKGROUND INFORMATION: The use of yeast in food production is the oldest and most extensive contribution made by any group of microorganisms. A most common substrate that yeast can work with is GLUCOSE. Glucose is a monosaccharide, which are sweet crystalline sugars that dissolve easily in water to form sweet solutions
the country slowly off of the gasoline fix and to look into alternative fuels to replace the “never coming back” fossil fuels. It turns out that Ethanol as a hybrid fuel proves to be a notable candidate for this gasoline intervention, per say. Now the United States is currently looking to subsidize fossil fuel alternatives. However, before considering ethanol production as a governmental subsidy, using large amounts of hard earned tax payer money, there has to be many alternative factors that come into
yeast affects the rate of ethanol fermentation, then Non-expired Bread Machine will result in the fastest rate followed by Non-expired Quick Rise, Non-expired Traditional, and expired Quick Rise because Bread Machine has the smallest yeast granule size allowing it to dissolve faster, the pellet size of Quick Rise is smaller than Traditional suggesting that Traditional has a slower rate, and expired yeast loses its potency over time so it has the slowest rate of ethanol fermentation. Procedure The
Ethanol can be made from many different plant sugars including starch and cellulose. Starch ethanol is the most common biofuel used in the world. It is made from kernels of corn, which is very easy to break down. This means that corn is very easily converted into ethanol. On the other hand, cellulose is not easily broken down into ethanol. Cellulose is found in the cell walls of plants, and resembles plant armor. The cellulose combines with lignin, which makes plants woody. During the process of

Ethanol and Gas Prices Do the gas prices frustrate you every time you pull up to the pump? Gas companies are charging too much for the natural resource that is turned into what we know as gasoline. Gas companies discourage research and new ideas every year. Afraid of losing the market that they have cornered they buy patents. This way the patents will never be used and they still have the market cornered. Ethanol is a much safer and more economical solution to our gas problem. It is cleaner
using relatively recent organic sources, have been around just as long as cars have. In fact, the first cars ran on peanut oil. Henry Ford, founder of a multimillion dollar American car company, planned to fuel his massively successful Model T’s with ethanol (National Geographic 2013.) However, this revolutionary idea was swept under the rug when the discovery of massive petroleum deposits kept gasoline and diesel cheap and affordable. As 2014 rolls around, consumers are starting see that the amount of
United States we have been looking into alternative energies to reduce our dependence on oil and help reduce our carbon footprint. One method the EPA has come out in support of is ethanol production. Ethanol is considered a green fuel because it recycles the burned carbon each time new crops are grown. In theory ethanol is a good stepping stone between using gasoline and zero emission power sources. However biofuels are still young technology that has many problems before it can be useful. The EPA
Ethanol is a clear, colorless, flammable liquid. Other names that ethanol can also be known as include ethyl alcohol, ethyl hydrate, ethyl hydroxide, fermentation alcohol, methylcarbinol, and grain alcohol. The condensed structural formula for ethanol is C2H5OH, and the expanded structural formula is shown in figure 1. This chemical compound belongs to the alcohol function group therefore characterized by the hydroxyl group –OH combined with a carbon atom. Some characteristics of ethanol include
Biodiesel vs. Ethanol Both biodiesel and ethanol are derivatives of biomass that have been processed to create a liquid biofuel. Both types of biofuels have been touted as secure and environmentally safe alternatives to fossil fuels, however the research verifying these claims is extensive but often contradicting. In the following paper, the efficiency and quality of the two types of biofuel will be discussed. The effects of variables such as source materials and production techniques on efficiency
production, making it a more ‘clean’ source of energy. The two main categories in fuels are gasoline (ethanol), a flammable and explosive liquid used mostly to power automobiles, and diesel, a relatively settled fuel used in diesel engines. This also applies to the world of biofuels. While diesel made by renewable resources is called biodiesel, gasoline made by living organisms is mainly ethanol fuel. Ethanol fuel is one of the most widely used biofuels in the world, as its market share in the United States
Ethanol production was developed in hopes of severing our ties with fossil fuels in favor of alternative energy, such as biofuels. Although, VOCs emissions are released during production of ethanol in a factory, the quality of air is greatly improved when burning ethanol versus fossil fuels. Burning ethanol instead of fossil fuels reduces the amount of cancer-causing greenhouse gases that go into the atmosphere. Ethanol production ranks at the bottom of industrial water usage, but is still not out
A Modest Proposal for Methanol and Ethanol Powered Cars "We need more stringent regulations on car emissions... Let's add MTBE to the fuel- that will reduce pollution... If people would just stop driving so much, pollution wouldn't be so bad..." People have long recognized the problems with the gasoline we used now. We have tried everything from putting regulations on emissions, to putting additives in the gasoline (only to discover later that MTBE got into the groundwater), to campaigns to
Should corn ethanol be used for fuel? Alternative energy is the world’s race as of now. As the space race concluded and the nuclear arms race died down, alternative energy became the race of the ages. In today’s society, with today’s technology there are all sorts of forms of alternative energies. These energies include hydro power, geothermal, biomass, nuclear power, and so much more. With all of these variations of alternative energy the question now becomes, which form is the best to use? Are
