Glycerol is a good alternative source for butanol production. While glucose sources are valuable and limited, glycerol is abundant and has a low market price because it is a waste product of biodiesel production. Butanol production from glycerol is economically viable using metabolic pathways that exist in the bacterium Clostridium pasteurianum ...
Butanol (also called butyl alcohol) is a four-carbon alcohol with a formula of C 4 H 9 O H, which occurs in five isomeric structures (four structural isomers), from a straight-chain primary alcohol to a branched-chain tertiary alcohol; [1] all are a butyl or isobutyl group linked to a hydroxyl group (sometimes represented as BuOH, sec-BuOH, i-BuOH, and t-BuOH).
Butanol is an alcohol which can be used as a fuel in most gasoline internal combustion engines without engine modification. It is typically a product of the fermentation of biomass by the bacterium Clostridium acetobutylicum (also known as the Weizmann organism).
1-propanol, 1-butanol, and isobutyl alcohol for use as a solvent and precursor to solvents; C6–C11 alcohols used for plasticizers, e.g. in polyvinylchloride; fatty alcohol (C12–C18), precursors to detergents; Methanol is the most common industrial alcohol, with about 12 million tons/y produced in 1980.
Butanol combustion: C 4 H 9 OH + 6O 2 → 4CO 2 + 5H 2 O + heat Propanol combustion: 2C 3 H 7 OH + 9O 2 → 6 CO 2 + 8H 2 O + heat The 3-carbon alcohol, propanol (C 3 H 7 OH), is not often used as a direct fuel source for petrol engines (unlike ethanol, methanol and butanol), with most being directed into use as a solvent. However, it is used ...
By spraying butane directly into the throat, the jet of fluid can cool rapidly to −20 °C (−4 °F) by expansion, causing prolonged laryngospasm. [37] " Sudden sniffer's death" syndrome, first described by Bass in 1970, [ 38 ] is the most common single cause of solvent related deaths, resulting in 55% of known fatal cases.
The largest use of 1-butanol is as an industrial intermediate, particularly for the manufacture of butyl acetate (itself an artificial flavorant and industrial solvent). It is a petrochemical derived from propylene. Estimated production figures for 1997 are: United States 784,000 tonnes; Western Europe 575,000 tonnes; Japan 225,000 tonnes. [8]
Butyraldehyde is a component in the two-step synthesis of trimethylolpropane, which is used for the production of alkyd resins. [ 5 ] A major use of butyraldehyde is in the production of bis(2-ethylhexyl) phthalate , a major plasticizer.
