Isobutanol (IUPAC nomenclature: 2-methylpropan-1-ol) is an organic compound with the formula (CH 3) 2 CHCH 2 OH (sometimes represented as i-BuOH). This colorless, flammable liquid with a characteristic smell is mainly used as a solvent either directly or as its esters.
Butanol (n-butanol or isobutanol) is a potential biofuel (butanol fuel). [8] Butanol at 85 percent concentration can be used in cars designed for gasoline (petrol) without any change to the engine (unlike 85% ethanol), and it contains more energy for a given volume than ethanol and almost as much as gasoline, and a vehicle using butanol would ...
Isobutanol is a second-generation biofuel with several qualities that resolve issues presented by ethanol. [10] Isobutanol's properties make it an attractive biofuel: relatively high energy density, 98% of that of gasoline. [39] does not readily absorb water from air, preventing the corrosion of engines and pipelines. [10]
The olive branch was a sign of peace in ancient Greek and Roman cultures. Renewable fuel producers and refiners could sure exchange one right now. Source: Wikimedia Commons / Marie-Lan Nguyen. The ...
In the context of butanol fuel, isobutyraldehyde is of interest as a precursor to isobutanol. E. coli as well as several other organisms has been genetically modified to produce isobutanol. α-Ketoisovalerate, derived from oxidative deamination of valine, is prone to decarboxylation to give isobutyraldehyde, which is susceptible to reduction to the alcohol: [3]
With a flash point of 35 °C, 1-butanol presents a moderate fire hazard: it is slightly more flammable than kerosene or diesel fuel but less flammable than many other common organic solvents. The depressant effect on the central nervous system (similar to ethanol intoxication) is a potential hazard when working with 1-butanol in enclosed spaces ...
“Revoking the authorized use of Red No. 3 is an example of the FDA using its risk and science-based authority to review the safety of products in the marketplace,” senior vice president of ...
The FDA’s recent ban on Red Dye No. 3, set to take effect by 2027 for foods and 2028 for drugs, marks a significant step in addressing safety concerns over artificial food dyes in the U.S. food ...
