Aldol n. (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.
... CH3MgI —> CH3.CH (CH3)2CH.OH MgI.OH. OMgI The lower members of the aliphatic series are characterized by their power of polymerization (see FORMALIN, and the account of Acetaldehyde below), and also by the so-called "aldol'' condensation, acetaldehyde in this way forming aldol, CH3.CHOH.CH2.CHO. These aldols generally lose the elements of water readily and pass into unsaturated compounds; aldol itself on distillation at ordinary atmospheric pressure gives crotonaldehyde, ... — Project Gutenberg Encyclopedia
