Infobox references

sec-Butanol or 2-butanol is an isomer of butanol, mainly used as a precursor to the more common methyl ethyl ketone.

Properties

Chemical

sec-Butanol can be oxidized to butanone.

Physical

2-Butanol is a colorless liquid, with a strong smell. It melts at −115 °C and boils at 99.5 °C, just slightly below the boiling point of water.

Availability

2-Butanol is sold by various chemical suppliers.

Preparation

Can be made by reducing butanone.

Projects

  • Make butanone

Handling

Safety

sec-Butanol is prone to forming explosive peroxide over the course of several years, so it's best to check it periodically.

Storage

In closed bottles, in the solvent cabinet.

Disposal

sec-Butanol can be safely burned, unless it has peroxides.
