Ethanol is a flammable, colorless chemical compound.
One of the alcohols that is most often found in alcoholic drinks, it is also known as ethyl alcohol or grain alcohol.
Ethanol is used as a solvent, an antiseptic, a fuel and the active fluid in modern (post-mercury) thermometers.
70% Ethanol is a more effective disinfectant because pure alcohol on a single celled organism triggers coagulation (clot) preventing it from penetrating deeper into the cell wall rendering it dormant but still alive. The water in 70% ethanol allows it to penetrate before it can clot.
In Brazil, ethanol fuel made from sugar cane provides 18 percent of the country's fuel for cars. Because of this, Brazil does not have to buy oil from other countries.
The grain required to fill a 25-gallon SUV gas tank with ethanol will feed one person for a year.
If you add 250ml of ethanol to 250ml of water, you get less than 500ml of liquid. This is because strong hydrogen bonding draws the different molecules closer together, and because ethyl molecules interfere with any open spaces in the water, causing them to pack closer together.
You would need an area three times the size of the continental United States to replace one-third of the United States’ oil requirements with ethanol.
