3-Oxetanone is used as a starting material for the preparation of other oxetanes compounds, which are of pharmacological interest. It is also considered as an object for theoretical studies. | [Definition]
3-oxetanone (1,3-epoxy2-propanone, c?C3H4O2) is a highly strained molecule functional in ring expansion and addition reactions. This molecule has also been proposed as a decomposition product of acetonylperoxy radical in the atmosphere. 3-oxetanone is suspected in the decomposition of the acetonylperoxy radical, an intermediate formed during the atmospheric processing of acetone. Atmospheric acetone degradation produces the acetonyl radical, CH3C(O)CH2, which reacts with O2 to form the acetonylperoxy radical. Rate constants predicted by a canonical variational theory/small-curvature tunneling method show that the radical isomerising produces 3-oxetanone and hydroxyl radical. These are the dominant products in the 250?2000 K range. There is no significant branching to other products below 1200 K. The only published study of the dissociation of 3-oxetanone is a Rice-Ramsperger-KasselMarcus (RRKM) analysis of the unimolecular rate constant for the photolysis of 3-oxetanone, producing ketene and formaldehyde[1-2].
| [General Description]
Product may polymerize over time during storage. | [Synthesis]
the synthesis method takes the chloroepoxypropane as a raw material, and
synthesizes the 3-oxetanone by five steps of ring-opening reaction,
addition reaction, cyclization reaction, hydrolysis reaction and
oxidation reaction.
