Iso-butanol (IB), also known as isobutyl alcohol or 2-methyl-1-propanol, is another isomer of butanol. It has a branched molecular structure with a methyl (-CH3) group attached to the secondary carbon atom. This structural difference gives iso-butanol distinct properties and uses
-
Solvents: Like n-butanol, iso-butanol is used as a solvent in various industries, including paints, coatings, inks, and adhesives. Its solvency power and evaporation rate make it suitable for these applications.
-
Chemical Intermediates: Iso-butanol serves as an intermediate in the production of other chemicals. It can be used in the synthesis of plastics, resins, and other organic compounds
-
Flavors and Fragrances: Iso-butanol is used in the production of flavors and fragrances due to its ability to enhance certain aromatic qualities.
-
Pharmaceuticals: Similar to n-butanol, iso-butanol can be used in the extraction and purification processes for certain pharmaceutical compounds.
-
Fuel Additive: Iso-butanol has been investigated as a potential biofuel additive due to its favorable properties as an oxygenate and octane booster in gasoline.
-
Anti-Icing Agent: In some cases, iso-butanol has been used as an anti-icing additive for aviation fuels to prevent the formation of ice crystals at low temperatures.
-
Polymer Production: Iso-butanol can be used in the production of polymers and plastics.
-
Cleaning Products: It can be found in some cleaning products and industrial formulations due to its solvent properties.
-
Herbicides and Pesticides: Iso-butanol can be used in the formulation of certain herbicides and pesticides.
