An Overview of Ethanol

Ethanol, (CH CH OH), is a clear, colourless liquid with a characteristic odour. Ethanol is an alcohol. In a dilute aqueous solution, it has a gentle flavour, but in more concentrated solutions it has a importunate taste. Alcohol originally referred to a fine powder, but gallant chemists later applied the term to the refined products of distillation, and this led to its current usage.

Ethanol melts at -114°C, boils at 78.5°C, and has a density of 0.789 g/mL at 20°C. Because of its low freezing point it is profitable for the fluid in thermometers for temperatures below -40°C, (the freezing point of mercury), and for separate low temperature purposes, such as antifreeze in automobile radiators.

Ethanol has been do since ancient times by the fermentation of sugars. It has two strands of uses; virtuoso as a beverage and the other for industrial purposes. every(prenominal) beverage ethyl alcohol and more than half of industrial ethanol is still made by the process of fermentation.

Most ethanol non intended for drinking is now made synthetically, either from ethanal made from acetylene, or from ethylene made from petroleum. Ethanol weed be manipulated to form acetaldehyde, acetic acid, ether, butadiene, chloroform, and many other radical chemicals.

Ethanol is used as an automotive fuel by itself and loafer be mixed with gasoline to form gasohol- the most jet blends contain 10% and 90% ethanol mixed with gasoline. Because the ethanol molecule contains oxygen, it allows for more complete combustion of fuel, resulting in less emissions. Ethanol is also called a renewable fuel and then has advantages as an automotive fuel.

Ethanol is mixable in all proportions with piddle and with most organic consequences. It is useful as a solvent for many substances and in making perfumes, paints, lacquer, and explosives.
