Ethanol is a chemical compound, a simple alcohol with the chemical formula C 2 H 5OH. Its formula can be also written as CH 3−CH 2−OH or C 2H 5−OH (an. Ethanol, or ethyl alcohol, is a type of alcohol, which is a hydrocarbon with one or more hydroxyl (-OH) groups substituted in place of one or. The main difference between ethanol and other types of alcohol is that ethanol is the only kind you can drink.
Symptoms of exposure to ethanol may include irritation to the eyes, skin and nose, drowsiness and headache. Other symptoms may include stupor, nausea, mental excitement or depression, vomiting, flushing and coma. Exposure to high concentrations of ethanol vapours may cause irritation of the eyes, skin and respiratory tract, loss of coordination ataxia , sleepiness, narcosis stupor or unconsciousness , impaired perception and lack of coordination.
It can also cause lowered inhibitions, dizziness, shallow respiration, unconsciousness and death. Ethanol is harmful by ingestion, inhalation or by skin absorption. Ethanol can depress the central nervous system, the eyes and upper respiratory tract nose and throat. Ethanol can cause irritation, headache, fatigue and loss of concentration.
Consumption of ethanol during pregnancy may affect the unborn child, resulting in spontaneous abortion, developmental problems, or birth defects. This is known as 'foetal alcohol syndrome'. Chronic ingestion of ethanol may cause liver cirrhosis, affect the nervous system and affect the glands in humans.
Ethanol is rapidly oxidised by the body to carbon dioxide and water, with no cumulative effect. Concentrations below parts per million ppm usually produce no signs of intoxication. Exposure to ethanol can be from the intake of food or beverages containing alcohol or from a wide range of consumer products containing ethanol, or in from a wide range of industries that use or produce ethanol.
Ethanol is present in low levels in the environment, it is a natural product that results from the fermentation of plants. Safe Work Australia sets the workplace exposure standard for ethanol through the workplace exposure standards for airborne contaminants:. These standards are only appropriate for use in workplaces and are not limited to any specific industry or operation. Make sure you understand how to interpret the standards before you use them.
There is no guideline for ethanol in the Australian Drinking Water Guidelines. At low concentrations and amounts, ethanol is rapidly metabolised without apparent harm. At higher concentrations, such as a result of leaks or spills, ethanol can have acute effects on a wide range of biota, where it may cause microbial death ethanol is a disinfectant. Ethanol is carried in the water and air. It is soluble in water and is volatile, so it can be carried quite long distances. Ethanol will oxidise quickly less than a few days , with carbon dioxide and water as the final products.
Another type of fermentation reaction is lactic acid fermentation, which is what your body undergoes when you are exercising too intensely to allow oxygen consumption and processing to keep pace with your energy needs. Both kinds of fermentation are alternatives to aerobic respiration, in which glucose is processed in cell mitochondria through the Krebs cycle and the electron transport chain to yield energy in the form of ATP, or adenosine triphosphate.
Ethanol, while long known as the active ingredient in alcoholic beverages, has also come into increasingly common use as an "alternative" fuel, meaning that it is an alternative to the traditional fossil, or petroleum-based, fuels such as gasoline and natural gas. Today, upward of 98 percent of gasoline sold in the U.
The most common ratio is 90 percent gasoline another hydrocarbon, if you're keeping score to 10 percent ethanol. Some vehicles have more flexibility in terms of their engines' fuel-combustion properties, and these can operate using fuels that consist of over 50 percent ethanol and in some cases more than 80 percent. Ethanol is popular in the U.
At present, however, ethanol fuels cannot provide the same fuel economy as gasoline-operated vehicles, offering only about three-fourths of the fuel efficiency of standard cars. Ethanol is also used in the production of alcohol meant for drinking. People have used ethanol in its processed drinking forms, such as beer, for centuries to change the way they feel. In smaller quantities, it may relax the mind and allow some individuals to participate more easily in otherwise stressful social situations.
Unquestionably, however, because it is so easily abused and so widely available, drinking alcohol constitutes a major public health hazard. In the year , according to the U. Centers for Disease Control and Prevention, excessive alcohol consumption cost the U. Some 88, deaths per year are directly attributable to the effects of excessive drinking. Some people have a far greater tendency than others to become physically or psychologically dependent on alcohol-containing drinks, with much of this believed to be genetic.
Most experts believe there is really no safe limit in terms of operating a motor vehicle under the influence, but alcohol-related car crashes remain a tremendous source of preventable death and debility nationwide.

How Alcohol Works
Ethyl alcohol, also called ethanol, grain alcohol, or alcohol, a member of a class of organic compounds that are given the general name alcohols; its molecular. Ethanol, also called alcohol, ethyl alcohol and grain alcohol, is a clear, colorless liquid and the principle ingredient in alcoholic beverages like beer, wine or. Ethanol vs Alcohol. Ethanol and alcohol are the same, and they have the same physical and chemical properties. Ethanol is a type of alcohol.
