USES OF ISOBUTANOL:
Isobutanol is used in organic synthesis, as a latent solvent in paints and lacquers, an intermediate for coating resins, in paint removers, liquid chromatography, and some flavor concentrations.
Isobutanol is also used as: solvent (textile industry and production of paints and lacquers), extraction agent in production of medicines, component of anti-icing mixtures and anti-corrosion additives.
Isobutanol can be used in a variety of ways, e.g. as a feedstock in the production of isobutyl acetate or as a varnish remover.
Isobutanol is widely used in the productionof isobutyl acetate for lacquers, isobutylphthalate for plasticizers; as a solvent forplastics, textiles, oils, and perfumes; and asa paint remover.

CHARACTERISTICS OF ISOBUTANOL:
Isobutanol (IBA), also called isobutyl alcohol, is a 4-carbon branched-chain alcohol.
Isobutanol is hardly soluble in water, but is soluble in almost all organic solvents.
Isobutanol has very low-level impurities and may be used as a raw material for a wide variety of chemicals.
PRODUCTION OF ISOBUTANOL:
Isobutanol is produced by the carbonylation of propylene.
The reaction is catalyzed by cobalt or rhodium complexes.
The resulting aldehydes are hydrogenated to the alcohols, which are then separated.
In Reppe carbonylation, the same products are obtained, but the hydrogenation is effected by the water-gas shift reaction.
STORAGE OF ISOBUTANOL:
Fireproof.
Separated from strong oxidants and aluminium
