CH2CHOCH2
CH2CHOCH2, also known as acrolein dimer or 2-formyl-3,4-dihydro-2H-pyran, is a cyclic acetal formed by the Diels-Alder reaction of acrolein with itself. It is a colorless liquid with a characteristic odor. The compound exists as a mixture of isomers due to the presence of a chiral center. Its chemical formula is C6H8O2.
Acrolein dimer is typically produced by heating acrolein, a reactive aldehyde. The reaction is reversible and
Industrially, acrolein dimer serves as an intermediate in the synthesis of various chemicals. It is used in
