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).
However, it is used as a source of hydrogen in some types of fuel cell; it can generate a higher voltage than methanol, which is the fuel of choice for most alcohol-based fuel cells. However, since propanol is harder to produce than methanol (biologically or from oil), methanol-utilizing fuel cells are preferred over those that utilize propanol.
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 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-Butanol, also known as butan-1-ol or n-butanol, is a primary alcohol with the chemical formula C 4 H 9 OH and a linear structure. Isomers of 1-butanol are isobutanol, butan-2-ol and tert-butanol. The unmodified term butanol usually refers to the straight chain isomer.
The term alcohol originally referred to the primary alcohol ethanol (ethyl alcohol), which is used as a drug and is the main alcohol present in alcoholic drinks. The suffix -ol appears in the International Union of Pure and Applied Chemistry (IUPAC) chemical name of all substances where the hydroxyl group is the functional group with the ...
The production of butanol by biological means was first performed by Louis Pasteur in 1861. [5] In 1905, Austrian biochemist Franz Schardinger found that acetone could similarly be produced. [ 5 ] In 1910 Auguste Fernbach (1860–1939) developed a bacterial fermentation process using potato starch as a feedstock in the production of butanol.
Acetone, butanol, and ethanol are the most common products of solventogenesis. Some species such as Clostridium beijerinckii, Clostridium puniceum and Clostridium roseum are able to further reduce acetone to isopropanol. Several species are able to produce additional solvents under various culture conditions.
