Description

Isobutyl alcohol (Isobutanol, 2-methyl-1-propanol) is a monohydric, simple alcohol used primarily as a solvent. It is easily mixed with most organic solvents, highly soluble in water.

Applications

Isobutyl alcohol is mainly used as a solvent in the production of varnishes and paints, for the preparation of plasticizers, and is included in the composition of numbering solvents.

Isobutanol is also present in additives to oils and fuels; it acts as an additive in the production of rubber, printing inks, and nitrocellulose.

In the pharmacological industry, isobutyl alcohol can be used as part of the essences.
