  2. Butanol - Wikipedia

    en.wikipedia.org/wiki/Butanol

    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).

  4. Butanol fuel - Wikipedia

    en.wikipedia.org/wiki/Butanol_fuel

    Butanol, a C-4 hydrocarbon is a promising bio-derived fuel, which shares many properties with gasoline. Butanol may be used as a fuel in an internal combustion engine. It is more similar to gasoline than it is to ethanol. A C4-hydrocarbon, butanol is a drop-in fuel and thus works in vehicles designed for use with gasoline without modification. [1]

  5. Water softening - Wikipedia

    en.wikipedia.org/wiki/Water_softening

    Since these systems do not work by exchanging ions, like traditional water softeners do, one benefit claimed for the user is the elimination of the need to add salt to the system. Such systems do not remove minerals from the water itself. Rather, they can only alter the downstream effects that the mineral-bearing water would otherwise have.

  6. 2-Butanol - Wikipedia

    en.wikipedia.org/wiki/2-Butanol

    Like other butanols, butan-2-ol has low acute toxicity. The LD 50 is 4400 mg/kg (rat, oral). [6]Several explosions have been reported [7] [8] [9] during the conventional distillation of 2-butanol, apparently due to the buildup of peroxides with the boiling point higher than that of pure alcohol (and therefore concentrating in the still pot during distillation).

  7. 1-Butanol - Wikipedia

    en.wikipedia.org/wiki/1-Butanol

    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.

  8. Alcohol fuel - Wikipedia

    en.wikipedia.org/wiki/Alcohol_fuel

    Scientific evidence reveals that water is an inhibitor for corrosion by ethanol. [6] The experiments are done with E50, which is more aggressive and speeds up the corrosion effect. It is very clear that by increasing the amount of water in fuel ethanol one can reduce corrosion. At 2% or 20,000 ppm water in the ethanol fuel the corrosion stopped.

  9. Isobutanol - Wikipedia

    en.wikipedia.org/wiki/Isobutanol

    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.
