Hydroxyacetone

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 structure. It is a colorless, distillable liquid. 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 structure. It is a colorless, distillable liquid. It is produced commercially by dehydration of glycerol. Hydroxyacetone is commercially available, but it also may be synthesized on a laboratory scale by a substitution reaction on bromoacetone. It undergoes rapid polymerization, including forming a hemiacetal cyclic dimer. Under alkaline conditions, it undergoes a rapid aldol condensation. Hydryoxyacetone can be produced by degradation of various sugars. In foods, it is formed by the Maillard reaction. It reacts further to form other compounds with various aromas. As such it finds some use as a flavoring.
