Description
- Isobutanol (IBAL) is a clear, mobile, neutral liquid with a characteristic odour. It is miscible with all common solvents, e.g. alcohols, ketones, aldehydes, ethers, glycols and aliphatic hydrocarbons. Its miscibility with water, however, is limited.

Application
- Isobutanol (IBAL) is used as a solvent in the coating industry, printing inks and as a solubilizer in the textile industry and as a feedstock in the production of glycols ether, flotation acid (e.g. isobutylxanthante), wear inhibitor and anticorrosion additives in engine oils.
- Other applications for Isobutanol are used as an extractant in the production of drugs and natural substances such as antibiotics, hormones, alkaloids and camphor. Also as an additives in alkyd resin paint, polishes and cleaners.
