What do you think of when I say Chloroform? You would probably think of something along the lines of spies and television burglars. Chloroform has been overly dramatized as an incredible “knock-out” liquid that a drop on a cloth can instantly get somebody unconscious. This is simply not true though. Although chloroform is an anesthesia, it is very unpractical and isn’t very applicable to any of the stories that you hear. Chloroform used to be made to the need of doctors without anesthetics. The main way to produce chloroform is by adding bleaching powder, water, and ethanol.
Ethanol has been used throughout history in a variety of ways. Every time you look at any alcoholic beverage, you are looking at a small amount of ethanol. Ethanol is what makes alcoholic beverages alcoholic. Rubbing alcohol is considered high concentrations of ethanol. Ethanol is also used as a fuel source in certain cars.
Ethanol, written as C2H6O or CH3CH2OH, has a low melting point at -144oC and a boiling point at 78oC. Because of its’ low melting point, it can be used in thermometers below -40oC. The density is also 0.789 g/mL when it is at 20oC. The chemical production of ethanol is quite simple. Fermenting simple sugar using Zymase, an enzyme from yeast, produces ethanol and carbon dioxide. The chemical formula is quite simple and can be demonstrated by this: C6H12O6 → 2 CH3CH2OH + CO2.
At this point in time, there are two ways to make ethanol naturally, wet milling and dry milling. Wet milling is the process of milling any grain and then cooking it. The cooked grain is then liquidized and fermented. It is then distilled and the solids get removed. The liquid is then passed through a molecular sieve, a filter, and mixed with a denaturant. The mix ...

Ethanol is a clean, renewable fuel made from plant material. Ethanol is cleaner than gasoline because it contains more oxygen. The added oxygen increases ethanol's octane rating. The octane rating is the fuel's ability to resist “knock”. Ethanol has a higher octane rating than gasoline. Ethanol above fifteen percent can damage vehicles that are designed to run on gasoline. An ethanol/gasoline (E10) blend is cheaper than just gasoline. The blend does reduce fuel economy by up to 3.3 percent. Car companies have started to produce flex-fuel vehicles. These flex-fuel vehicles can run on fuel with up to 85 percent ethanol. The main problem is
Ethanol Fermentation: the process of chemically breaking down bacteria/yeast in an anaerobic environment, which in turn releases CO2.

Throughout this experiment ethanol is the alcohol which is produced during the fermentation process of sugar which is present in the grape must or juice.
This unknown molecule or molecules could be oxygen, nitric oxide, or ammonia, all of which are known to negatively affect cells. This article was published in 2004 and, the follow up experiment that addresses these impurities was conducted by the same people in 2005. In this experiment they found that the gas did in fact have many impurities and an extensive gas cleaning procedure needed to be implemented in order to effectively harvest ethanol from the bacteria P7. The molecule that was mostly responsible for disrupting the cell was nitric oxide. All in all it seems entirely viable to use this biological process in order to manufacture ethanol for wide spread use.
Alcoholic beverages all share a common characteristic, they were all developed with the use of anaerobic fermentation of carbohydrates by the use of yeasts. Majority of plant matter can be used as a source to
One day I pulled up to a gas station, and to my surprise I saw a new sticker on the pump. The sticker read,” Fuel may contain 10% Ethanol.” I was a little taken back by the sticker. I didn’t have a full understanding of why ethanol was being used in the fuel for my car. I knew that ethanol was a bi-product of corn and other plants, so I found myself asking the question, is corn for food or fuel? I got back into my car and returned to the freeway with this question on my mind. While driving I started noticing stickers and labels on other vehicles that read: CNG (compressed natural gas), Flex Fuel (allows vehicles to go between 2 different fuels), HEV (Hybrid Electric Vehicle), and Bio-diesel (cleaner burning diesel fuel, made from plants or vegetable oils). As I pondered about the various labeling, I found myself most curious about ethanol and other bio-fuel products.
Biobutanol has the potential to replace ethanol as a fuel in the future. Recent studies suggested that it does not damage car engines like ethanol does, it reduces fuel mileage , and it can blended with gasoline directly in the refinery. In conclusion, butanol can make up for ethanol’s weaknesses. However, butanol fuel is said to be too expensive and not competitive enough to compete with ethanol.
Based on the data obtained, Table 1 demonstrates that when obtaining the percent recovery of ethanol, 25% ethanol was obtained. This represents a relatively good percent recovery because ideally about 30.1% ethanol should have been produced. According to Chemspider, the density of ethanol is 0.8 g/〖 cm〗^3 and the density of water is 1.00 g/〖 cm〗^3. Therefore, all of the densities present in Table 1 may be incorrect due to a variety of reasons, such as incorrectly recording the mass or volume of the product. The volume could have been perceived as a different number because perception varies from person to person. However, the data results make sense because none of the densities reported were below 0.8g/〖 cm〗^3 or higher than 1.00 g/〖 cm〗^3, therefore, the data results were relatively accurate, but probably contained impurities.
Alcohol is a colorless, volatile flammable liquid that is the intoxicating constituent of wine, beer, spirits, and other drinks and is also used as an industrial solvent and as fuel. Alcohol is a drug and it is classed as a depressant, meaning that it will slow down vital functions. Alcohol is made out of a chemical called ethanol. To make alcohol, they need to have the grains, fruits or vegetables go through a process called fermentation.
Fermentation is one of the process of glycolysis, it is anaerobic, basically this means that it does not use air. Its end product is ethanol, which is a form of alcohol, ethanol differs from alcohol in its chemical composition. The end product of ethanol from glycolysis can be explained by the following equation.
Alcohol is an ethanol containing substance that is a common beverage in many social and private settings. Alcohol is also a teratogen, therefore alcohol co...
Also known as alcoholic fermentation, this process is occurs in an anaerobic environment. In alcoholic fermentation, glucose molecules are degraded into two molecules of ethanol and two molecules of carbon dioxide. In production of alcohol, first, glycolysis process will breakdown glucose molecule into to pyruvic acid. Then, carboxyl group of the pyruvic acid will be removed and causing carbon dioxide to be excreted. The NADH then left its hydrogen onto the second carbon molecule creating ethanol. The overall chemical reaction are as follows :
Alcohol is made through a process called fermentation (how alcohol is made). It is the process of sugar being broken down into carbon dioxide and ethanol. The main ingredient in fermentation is yeast. Yeast breaks down grains, fruits, and its main function is to get the alcohol
Alcohol is a class of organic compounds that is characterized by the presence of one or more hydroxyl groups (-OH) attached to a carbon atom. Alcohol was unknowingly produced centuries ago when fermentation occurred to crushed grapes (Pines, 1931). In today’s society alcohol is produced for the use of household products such as varnishes, cleaning products, but is more commercially important in the liquor business. A chemical process called fermentation accomplishes the production of ethanol, the alcohol or liquor. From there, the ethanol goes through distinct processes to become the dark and clear liquors on the store shelves.
