sec-Butanol or 2-butanol is an isomer of butanol, mainly used as a precursor to the more common methyl ethyl ketone.
Contents
Properties
Chemical
sec-Butanol can be oxidized to butanone aka methyl ethyl ketone.
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.
