Acetaldehyde
a volatile, colorless, water-soluble liquid, C 2 H 4 O, having a pungent, fruitlike odor: used chiefly in the silvering of mirrors and in organic synthesis.
Historical Examples
The decomposition of pyruvic acid into acetaldehyde and carbon dioxide has already been fully discussed (Chapter VI).
Alcoholic Fermentation Arthur Harden
Starting in the one case with fused paraldehyde, and in the other case with acetaldehyde, the same freezing point, viz.
The Phase Rule and Its Applications Alexander Findlay
For this reason it is possible to determine the freezing point curves of acetaldehyde and paraldehyde.
The Phase Rule and Its Applications Alexander Findlay
This is in harmony with the fact that the polymerisation of acetaldehyde is accompanied by evolution of heat.
The Phase Rule and Its Applications Alexander Findlay
acetaldehyde is not of much importance in itself, but is useful as a transition.
Creative Chemistry Edwin E. Slosson
acetaldehyde, which is halfway between alcohol and acid, may also be easily oxidized to acetic acid.
