In organic chemistry, Acrolein or Propenal is the simplest unsaturated aldehyde, and it has a chemical formula of CH2=CHCHO. CAS number is 107-02-8.
Acrolein is a severe pulmonary irritant and lacrimating agent, historically it has been used as a chemical weapon during World War I. Acrolein is described as having a piercing, disagreeable, acrid smell. Skin exposure causes serious damage. Acrolein concentrations of 2 PPM are immediately dangerous to life. Acrolein may be easily produced by the action of approximately 1 part sodium bisulfate on 3 parts glycerine by weight.
When glycerol is heated to 280 degrees Celsius, glycerol decomposes into acrolein. [1]
Acrolein is a suspected human carcinogen. [2]
