Isobutanol is a medium boiling, slow vaporizing, transparent liquid that is useful in organic synthesis, as a transition product in plasticizers, pesticides, food essences, drugs manufacture and as a solvent for a wide variety of chemical and textile processes. As a latent solvent in lacquers and ambient-cured enamels, isobutanol is effective in reducing the viscosities of many formulations while simultaneously promoting flow and leveling. It is also used as an etherification alcohol in the manufacture of amino resins that are used as curing agents in baking and physical-drying finishes.
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 production of plastics, rubbers, and other dispersion, precursor of p-xylene, a building block for plastic bottles, textiles and clothing
paint additive, when it is needed 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
Isobutanol is a transparent liquid with a strong alcoholic odor. It is miscible with a number of organic solvents. Isobutanol dissolves in water and forms azeotropic solution with it (26.8% H2O by mass, bp 87.0°C). Isobutyl alcohol is a typical aliphatic alcohol.
