  • noun A thick, colorless to pale yellow liquid, C4H8O2, obtained from acetaldehyde and used in perfumery and as a solvent.
  • noun An organic compound containing an alcohol and a carbonyl group, especially a beta-hydroxy aldehyde.
  • noun A chemical reaction that produces a beta-hydroxy carbonyl compound as an intermediate or final product.

  • noun (Chem.) A colorless liquid, C4H8O2, obtained by condensation of two molecules of acetaldehyde: CH3CHO + CH3CHO = H3CH(OH)CH2CO; also, any of various derivatives of this. The same reaction has been applied, under the name of aldol condensation, to the production of many compounds.
