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 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. The suffix -ol appears in the International Union of Pure and Applied Chemistry (IUPAC) chemical name of all substances where the hydroxyl group is the functional group with the ...
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.
Distilled spirits contain ethyl alcohol, the same chemical that is present in beer and wine, and as such, spirit consumption has short-term psychological and physiological effects on the user. Different concentrations of alcohol in the human body have different effects on a person.
A tincture is typically an extract of plant or animal material dissolved in ethanol (ethyl alcohol). Solvent concentrations of 25–60% are common, but may run as high as 90%. [83] In chemistry, a tincture is a solution that has ethanol as its solvent.
For example, ordinary vodka, gin, rum and tequila have an alcohol concentration typically around 40% alcohol by volume (80 proof), and liqueurs are typically around 20% alcohol (40 proof). [ 6 ] Everclear is also used as a household "food-grade" cleaner, disinfectant, or stove fuel alcohol because its fumes and odor are less offensive than ...
Ro15-4513, a close analogue of the benzodiazepine antagonist flumazenil (Ro15-1788), has been found to bind to the same site as ethanol and to competitively displace it in a saturable manner. [21] [47] In addition, Ro15-4513 blocked the enhancement of δ subunit-containing GABA A receptor currents by ethanol in vitro. [21]
In the fuel ethanol this resembles 20,000 ppm or 2 volume% in the case of JARI and 5 x 3500 = 17,500 ppm of 1.75 volume% in the case of TU Darmstadt. The observations are in line with the fact that hydrous ethanol is known for being less corrosive than anhydrous ethanol. The reaction mechanism will be the same at lower-mid blends.
