Isobutanol (IUPAC nomenclature: 2-methylpropan-1-ol) is an organic compound with the formula (CH₃)₂CHCH₂OH (sometimes represented as i-BuOH). This colorless, flammable liquid with a characteristic smell is mainly used as a solvent.

Detailed description

Its isomers, the other butanols, include n-butanol, 2-butanol, and tert-butanol, all of which are important industrially.

Applications

Isobutanol has a variety of technical and industrial applications:

·         feedstock in the manufacture of isobutyl acetate, which is used in the production of lacquer and similar coatings, and in the food industry as a flavoring agent

·         precursor of derivative esters – isobutyl esters such as diisobutyl phthalate (DIBP) are used as plasticizers in plastics, rubbers, and other dispersions

·         precursor of p-xylene, a building block for plastic bottles, textiles and clothing.

·         paint solvent

·         varnish remover

·         ink ingredient

·         paint additive, to reduce viscosity, improve brush flow, and retard formation of oil residues (blush) on painted surfaces

·         gasoline additive, to reduce carburetor icing

·         automotive polish additive

·         automotive paint cleaner additive

·         chemical extractant in production of organic compounds

·         mobile phase in thin layer chromatography.

·         potential gasoline alternative

Second-generation biofuel

Isobutanol can be used as a biofuel substitute for gasoline in the current petroleum infrastructure. Isobutanol has not yet been put into mainstream use as a biofuel and would serve as a replacement for ethanol. Ethanol is a first-generation biofuel, and is used primarily as a gasoline additive in the petroleum infrastructure. Isobutanol is a second-generation biofuel with several qualities that resolve issues presented by ethanol.

Isobutanol's properties make it an attractive biofuel:^[7]

·         relatively high energy density, 98% of that of gasoline.^[21]

·         does not readily absorb water from air, preventing the corrosion of engines and pipelines.

·         can be mixed at any proportion with gasoline,meaning the fuel can "drop into" the existing petroleum infrastructure as a replacement fuel or major additive.

·         can be produced from plant matter not connected to food supplies, preventing a fuel-price/food-price relationship.
