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.
When phenol is treated with diazomethane in the presence of boron trifluoride (BF 3), anisole is obtained as the main product and nitrogen gas as a byproduct. C 6 H 5 OH + CH 2 N 2 → C 6 H 5 OCH 3 + N 2. Phenol and its derivatives react with iron(III) chloride to give intensely colored solutions containing phenoxide complexes.
Most gasoline now contains approximately 10-15% ethanol solution. [2] Current gasoline-powered automobiles can safely run with up to a 10% ethanol solution without requiring any modification. However, when the ethanol content reaches 15% or higher, older vehicles need to replace their fuel lines to prevent degradation and rupture. [2]
This Wikipedia page provides a comprehensive list of boiling and freezing points for various solvents.
Ethanol fermentation is not 100% selective with side products such as acetic acid and glycols. They are mostly removed during ethanol purification. Fermentation takes place in an aqueous solution. The resulting solution has an ethanol content of around 15%. Ethanol is subsequently isolated and purified by a combination of adsorption and ...

In line with the observations in Japan, hydrous ethanol is known to be less corrosive than anhydrous ethanol. The reaction mechanism is 3 EtOH + Al -> Al(OEt) 3 + 3 ⁄ 2 H 2 at lower-mid blends. When enough water is present in the fuel, aluminum will react preferably with water to produce Al 2 O 3 , repairing the protective aluminum oxide layer.
