Acrolein (IUPAC name: propenal) is the simplest unsaturated aldehyde, characterized by its pungent odor reminiscent of burnt fat. It is a colorless to yellowish liquid with the molecular formula C₃H₄O and a molecular weight of 56.06 g/mol. Acrolein is highly reactive, flammable, and toxic, requiring stringent safety measures during handling and storage.

Industrial Production

Acrolein is primarily produced through the vapor-phase oxidation of propylene using bismuth molybdate-based catalysts. This method has been the standard since the 1960s 

? Applications

• Chemical Synthesis: Acrolein serves as a precursor in the production of various chemicals, including:

  • Methionine: An essential amino acid used in animal feed

  • Acrylic Acid: Used in the manufacture of superabsorbent polymers and coatings

  • Glutaraldehyde: A disinfectant and crosslinking agent

  • Polyacrolein: A polymer used in adhesives and coatings

• Biocide: Employed as a contact herbicide and algaecide in irrigation systems and oil fields

• Laboratory Reagent: Used in the preparation of biological specimens for electron microscopy

• Warning Agent: Added to gases to detect leaks due to its strong odor
