Cyclohexene oxide is a cycloaliphatic epoxide. It can react in cationic polymerization to poly(cyclohexene oxide). As cyclohexene is monovalent, poly(cyclohexene oxide) is a thermoplastic.

Production[edit]

Cyclohexene oxide is produced in epoxidation reaction from cyclohexene. The epoxidation can take place either in a homogeneous reaction by peracids^[2] or heterogeneous catalysis (e.g. silver and molecular oxygen).^[3]^[4]^[5]

In industrial production the heterogeneously catalyzed synthesis is preferred because of better atom economy, a simpler separation of the product and easier recycling of catalyst. A short overview and an investigation of the oxidation of cyclohexene by hydrogen peroxide is given in the literature.^[6] In recent times the catalytic oxidation of cyclohexene by (immobilized) metalloporphyrin complexes has been found to be an efficient way.^[7]^[8]

In laboratory, cyclohexene oxide can also be prepared by reacting cyclohexene with magnesium monoperoxyphthalate (MMPP) in a mixture of isopropanol and water as solvent at room temperature.^[9]

With this method, good yields up to 85 % can be reached.

Properties and reactions[edit]

Cyclohexene has been studied extensively by analytical methods.^[10] Cyclohexene oxide can be polymerized in solution, catalyzed by a solid acid catalyst.^[11]
