Hydroxyacetone, also known as acetol, is the organic chemical with the formula CH3C(O)CH2OH. It consists of a primary alcohol substituent on acetone. It is an α-hydroxyketone, also called a ketol, and is the simplest hydroxy ketone.
Hydroxyacetone undergoes rapid polymerization, including forming a hemiacetal cyclic dimer.
Under alkaline conditions, it undergoes a rapid aldol condensation.
Hydroxyacetone is a colorless liquid, though contaminated samples may turn slightly yellow. It has a sweet-like odor and it's miscible with water. It is also hygroscopic.
Hydroxyacetone is sold by chemical suppliers.
- Preparation of pyruvic acid
Hydroxyacetone displays moderate to low toxicity. May be irritant to skin and sensitive tissues.
Hydroxyacetone should be kept in amber glass bottles, away from air and other reagents. Small amounts of pure sodium carbonate is sometimes used as stabilizer, though this doesn't appear to be always necessary.
Can be mixed with another solvent and burned in an incinerator. Alternatively, it can be diluted in water and poured down the drain.
