Ethanol burns in air with a blue flame, forming carbon dioxide and water. It reacts with active metals to form the metal ethoxide and hydrogen, e.g., with sodium it forms sodium ethoxide. It reacts with certain acids to form esters, e.g., with acetic acid it forms ethyl acetate. It...

Ethanol is flammable and burns more cleanly than many other fuels. Ethanol has been used in cars since Henry Ford designed his 1908 Model T to operate on alcohol. In Brazil and the United States, the use of ethanol from sugar cane and grain as car fuel has been promoted by government pro...
Brazil burns significant amounts of ethanol biofuel. Gas chromatograph studies were performed of ambient air in São Paulo, Brazil, and compared to Osaka, Japan, which does not burn ethanol fuel. Atmospheric Formaldehyde was 160% higher in Brazil, and Acetaldehyde was 260% higher.[74][needs ...
Using a quasi-steady heterogeneous experimental setup, the air velocity at which an envelope flame surrounding the sphere transits to a wake flame that burns in the rear region of the sphere, termed as the transition or the extinction velocity, were obtained in a previous study. These extinction...
The present paper is focused on prevaporised ethanol flames in the transition from conventional combustion to the MILD combustion regime. Photographs and imaging of OH * chemiluminescence reveal a distinctive flame structure when ethanol carried by air burns in a 3% O 2 coflow (typical of MILD ...

Why is ethanol in our gas? Fuel ethanol is used to enhance the octane rating of gasoline. To put that simply, higher octane gas resists detonation, so it burns rather than exploding. But raising the octane level of gasoline is expensive; that’s why premium fuel costs more than regular. ...
Metabolism in the larva of Polypedilum vanderplanki can be brought reversibly to a standstill by dehydration and exposure to very low or very high temperatures. Larvae metamorphosed after immersion in liquid air or liquid helium when dry... HE Hinton - 《Journal of Insect Physiology》 被引量: ...
