In the field of chemicals, acrolein and allyl aldehyde are two common monomers, and they have some obvious differences in structure and properties. In this paper, the differences between acrolein and allyl aldehyde will be discussed in depth, and the structure, properties and applications will be compared.

From the structural point of view, the chemical formula of acrolein is C3H4O, and its molecular structure contains an aldehyde group and an olefin group. The chemical formula of allyl aldehyde is C4H6O, and its molecular structure contains a ketone group and an olefin group. It can be seen that the molecular structures of acrolein and allylaldehyde are very similar, differing only in the aldehyde and ketone groups.

from the nature, acrolein and allyl aldehyde also have some differences. Acrolein is a colorless liquid with a pungent odor that is soluble in water and a variety of organic solvents. It is easy to polymerize and can also be reduced to allyl alcohol. Allyl aldehyde is a colorless liquid with a pungent odor and can be dissolved in water and a variety of organic solvents. Its main reaction mode is addition reaction, which can occur with many electrophiles.

from the application point of view, acrolein and allyl aldehyde have their own uses. Acrolein is commonly used in resins, coatings, plastics, textiles and other fields. Its polymer can be made into a variety of heat-resistant, chemical-resistant materials. Allyl aldehyde is commonly used in dyes, pharmaceuticals, pesticides and other fields. It can be used as an intermediate for the synthesis of dyes and also for the synthesis of various organic compounds.

In summary, there are some differences between acrolein and allyl aldehyde in structure, properties and applications. Understanding their differences is important for the correct use and selection of these two chemicals. In the process of use, we should abide by the relevant safety operation procedures to ensure the correct use and storage of chemicals to protect our health and environmental safety.
