I WILL MARK YOU BRAINLIEST Which method do you use to purify the impure ethanol produced from fermentation of glucose?
Also, which impurities does this ethanol contain?
Answers
Ethanol, also called alcohol, ethyl alcohol, and drinking alcohol, is a chemical compound, a simple alcohol with the chemical formula C
2H
5OH. Its formula can be written also as CH
3−CH
2−OH or C
2H
5−OH (an ethyl group linked to a hydroxyl group), and is often abbreviated as EtOH. Ethanol is a volatile, flammable, colorless liquid with a slight characteristic odor. It is a psychoactive substance and is the principal type of alcohol found in alcoholic drinks.
Ethanol is naturally produced by the fermentation of sugars by yeasts or via petrochemical processes, and is most commonly consumed as a popular recreational drug. It also has medical applications as an antiseptic and disinfectant. The compound is widely used as a chemical solvent, either for scientific chemical testing or in synthesis of other organic compounds, and is a vital substance utilized across many different kinds of manufacturing industries. Ethanol is also used as a clean-burning fuel source.
The process could be seen as carbon neutral because as the plant grows, it takes in carbon dioxide for photosynthesis. This therefore balances out the carbon dioxide released when it is fermented.
High amounts of energy are not needed as sugar is fermented at temperatures of around 35°c to 40°c. Low cost process because of low temperature.
