2-methyl -2-butanol is a chemical compound selected from the group of the alcohols, specifically the pentanols.

Production and representation

2-methyl -2-butanol is produced mainly by hydration of pentenes.

As prepared from 2- methyl -2-butene, or by hydroformylation of 1-butene, 2-butene or isobutylene with a mixture of carbon monoxide and hydrogen in the presence of a metal catalyst to give a mixture of isomers of C5 - aldehydes is that then the associated amyl alcohol, hydrogenated.

It can also be obtained by the fractionation of fusel oils.

Properties

2-methyl -2-butanol is a volatile, colorless liquid with an unpleasant odor, which is readily soluble in water. It decomposes upon heating and has a kinematic viscosity of 5 mm2 / s (23 ° C).

Use

2-methyl -2-butanol is used as solvent for oils, fats and many artificial and synthetic resins, paraffin, waxes, and the like.

Pharmaceutical use

2-methyl -2-butanol has been used under the name of amylene hydrate as a sedative.

Safety

The vapors of 2-methyl -2-butanol can form (19 ° C, ignition temperature 435 ° C flash point) with air to form an explosive mixture. They continue to have a narcotic effect.
