  • n. 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.

from The Century Dictionary and Cyclopedia

  • n. A compound, CH3CHOHCH2CHO, formed by the condensation of acetaldehyde by means of zinc chlorid. The official name is butanalol-3.
