Ethanol (also called ethyl alcohol, grain alcohol, drinking alcohol, or simply alcohol) is an organic compound with the chemical formula CH 3 CH 2 OH. It is an alcohol, with its formula also written as C 2 H 5 OH, C 2 H 6 O or EtOH, where Et stands for ethyl. Ethanol is a volatile, flammable, colorless liquid with a characteristic wine-like ...
The term ethanol was invented in 1892, blending "ethane" with the "-ol" ending of "alcohol", which was generalized as a libfix. [18] The term alcohol originally referred to the primary alcohol ethanol (ethyl alcohol), which is used as a drug and is the main alcohol present in alcoholic drinks.
Ethanol fuel is fuel containing ethyl alcohol, the same type of alcohol as found in alcoholic beverages. It is most often used as a motor fuel , mainly as a biofuel additive for gasoline . Several common ethanol fuel mixtures are in use around the world.
Perforated patch clamp technique was used having intracellular fluid inside the pipette and extracellular fluid in the bath with added 0.3% vol/vol (about 50-mM) ethanol. Ethanol decreased the Ca 2+ current in DSM cells and induced muscle relaxation. Ethanol inhibits VGCCs and is involved in alcohol-induced relaxation of the urinary bladder. [57]
However, the fuel systems of cars, trucks, and motorcycles sold before the ethanol mandate may suffer substantial damage from the use of 10% ethanol blends. Flexible-fuel cars, trucks, and minivans use gasoline/ethanol blends ranging from pure gasoline up to 85% ethanol . By early 2013 there were around 11 million E85-capable vehicles on U.S ...
Alcohols applied to the skin are used to disinfect skin before a needle stick and before surgery. [2] They may also be used as a hand sanitizer; [2] to clean other areas; [2] and in mouthwashes. [3] [4] [5] Taken by mouth or injected into a vein, ethanol is used to treat methanol or ethylene glycol toxicity when fomepizole is not available. [1]
Summary of the main ethanol blends used around the world in 2013. Several common ethanol fuel mixtures are in use around the world. The use of pure hydrous or anhydrous ethanol in internal combustion engines (ICEs) is only possible if the engines are designed or modified for that purpose, and used only in automobiles, light-duty trucks and motorcycles.
In 1860, German inventor Nicolaus Otto uses ethyl alcohol as a fuel in an early internal combustion engine. [6] In 1862 and 1864, a tax on alcohol was passed in the U.S. to pay for the Civil War, increasing the price of ethanol to over $2.00 per gallon. A new product from petroleum, called kerosene, is taxed at 10 cents a gallon. [7]
