About Isobutanol

  • Isobutanol , also called isobutyl alcohol, is an alcohol with the chemical formula C₄H₁₀O and one of the four isomers of butanol.
  • It is a clear, colorless liquid with a characteristic odor. 
  • It is only moderately soluble in water.
  • It is very flammable and has a flash point that is only slightly above normal room temperatures. 
  • Its vapors are heavier than air and can spread unnoticed along the ground. 
  • Skin contact, ingestion, and inhalation of isobutanol can be harmful to health. 
  • The compound causes skin irritation and severe eye damage, including loss of vision. 

Isobutanol Applications

  • It is used as a solvent in the flavor, fragrance, pharmaceutical, and pesticide industries and as a chemical manufacturing ingredient for products such as lacquer, paint strippers, paint primer, and craft paints.
  • It is an approved food additive and is also naturally occurring in some foods and many alcoholic beverages. 
  • Isobutanol may also be used as a biofuel because, like ethanol, it can be manufactured from plants. It can be made from ethanol using fermentation processes.
  • It possesses some favorable properties that make it an attractive fuel for internal combustion engines. 
    • For instance, when compared to ethanol, isobutanol features a higher heating value.
    • Isobutanol is less corrosive than ethanol and is much less hygroscopic, which enables it to be transported using the existing fuel infrastructure.
    • Moreover, its addition to gasoline does not distort the fuel blend’s vapor pressure to the same extent as ethanol does. All of this while having a high octane rating.
