Butanol - an overview ScienceDirect Topics

Butanol (n-butanol or isobutanol) is a potential biofuel (butanol fuel). 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 return fuel consumption more comparable to gasoline than ethanol. Butanol can also be added to diesel fuel to reduce soot emissions. Photo… WebJan 23, 2024 · Functional groups A. In organic chemistry, functional groups are specific groups of atoms within molecules arranged in a specific manner. The following tables list common functional groups arranged by heteroatom. The symbols R, R', R'' and R''' usually denote a hydrocarbon chain or a hydrogen but can sometimes be any group of atoms. WebThe heat of vaporization for butanol is 141.3 kcal kg −1 as compared to 204.1 kcal kg −1 for ethanol. In addition, the high boiling point (118 °C) and lower vapor pressure for butanol may enhance cold starting. There are various other properties that make butanol a superior fuel. お風呂うめる方言
