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 ...

...t a viable option to use as for fuel. Drinking alcohol is going to stay around for a long time is my guess. Alcohol is still used every day in nearly everybody’s homes.

Anesthetics were not used in surgery until October 16, 1846, in Massachusetts General Hospital (Youngson 51). The anesthesia was a inhaled gas known as ether. In 1847 a doctor by the name of James Simpson popularized chloroform as an alternative to ether. According to Simpson chloroform could do more with less, act faster and last longer than ether, is more pleasing to the senses than ether, and is cheaper (qtd. in Youngson 70). Chloroform also did not need an inhaling device like ether did; it could be placed on a piece of cloth and work just as well (Youngson 70).

Methanol and Ethanol have differences as Methanol melts at a higher temperature and boils at a lower temperature than Ethanol. Higher alcohols, which include Butanol and Propanol, have a higher molecular weight and this is why Butanol is used in perfumes. Ethanol, which is sugar based, with its low freezing point, has a specific use as an antifreeze for cars and other vehicles. GRAPH Tripod Matches Goggles Method: To begin with, I choose one of the four different alcohols. I weigh beforehand in the spirit burner.
They are as follows, Table #5 substituted glucose for sucrose and Table #6 substituted the glucose for pH4. The equation for alcohol fermentation consists of 6 Carbons, 12 Hydrogens, 6 Oxygen to produce 2 pyruvates plus 2 ATP. Then finally the final reaction will be 2 CO2 plus Ethanol. In the class our controlled numbers were at Table #1.
Ethanol is the only alcohol that can be drunk safely and is found in all alcoholic drinks. Throughout this investigation I am going to investigate to different factors that affect the breakdown of an alcohol. [IMAGE]e.g. Methane (HCO) + Oxygen (O2) Carbon dioxide (CO2) + Water (H2O) Aim --- I am going to investigate increasing the chain length and see what effect there is on the heat of combustion.
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...
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

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 :
Preparation of Ethanol and Ethanoic Acid Introduction to report ---------------------- This report contains 5 practical experiments to produce ethanoic acid from ethanol. The first practical is the preparation of ethanol from glucose using yeast during the process of fermentation; this has been demonstrated in class. In this practical the glucose is converted into ethanol and carbon dioxide by respiratory enzymes from the yeast. The ethanol solution will be between 5-15% and the ethanol will be separated from the yeast by filtering.
The purpose of this experiment is to compare the processes of distillation and fractional distillation to discover which procedure enables a more pure sample of ethanol to be collected from an ethanol/water mixture.
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.
