acrolein|əˈkrəʊliːɪn|
[f. L. acr-is sharp, pungent + olē-re to smell + -ine = Gr. -ινη daughter, derivative; here used to form a term analogous to glycerin.]
A colourless acrid liquid, of pungent irritating odour, formed in the destructive distillation of glycerin (from which it is derived by the abstraction of two molecules of water, thus, Glycerin C3H5(OH)3, Acrolein C3H4O{pp}). It is the aldehyde of allyl, produced by the oxidation of allyl alcohol, and itself rapidly oxidizing to acrylic acid.
