sec-Butanol can be oxidized to butanone aka methyl ethyl ketone using Jones reagent.
sec-Butanol burns in air to release carbon dioxide and water vapors.
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.
2-Butanol is sold by various chemical suppliers.
Can be made by reducing butanone using a reducing agent.
- Make butanone
sec-Butanol is prone to forming explosive peroxide over the course of several years, so it's best to check it periodically.
sec-Butanol should be kept in closed bottles, in the solvent cabinet.
sec-Butanol should be tested for peroxides before disposal. If peroxides are present, a reducing agent such as sodium sulfite should be added to destroy the peroxides, then tested again to see if all the peroxides have been neutralized. If no peroxides are present, it can be safely burned.
However, unless the waste sec-butanol is very old (at least several years) and wasn't stabilized with an anti-oxidant, there is little chance of building up a dangerous amount of peroxides. Nonetheless, a peroxide test is recommended for safety reasons.
