Acetaldehyde, CH3CHO is an important intermediate in industrial organic synthesis. Acetic acid, acetic anhydride, n-butanol, and 2-ethylhexanol are the major products derived from acetaldehyde. Smaller amounts of acetaldehyde are also consumed in the manufacture of pentaerythritol, trimethylolpropane, pyridines, peracetic acid,crotonaldehyde, chloral, 1,3-butylene glycol, and lactic acid.

Acetaldehyde (ethanal) was first prepared by Scheele in 1774, by the action of manganese dioxide and sulfuric acid on ethanol. Liebig established the structure of acetaldehyde in 1835 when he prepared a pure sample by oxidizing ethyl alcohol with chromic acid. Liebig named the compound “aldehyde” from the Latin words translated as al (cohol) dehyd (rogenated). Kutscherow observed the formation of acetaldehyde by the

addition of water to acety lene in 1881.
