Synthesis
In a threaded test tube, 1.00 g of fluorapatite (FAp) and 0.079 g (0.021 mmol) of catalyst (CetylPy)3 [PW12O40] were weighed, and then 0.134 g (1.02 mmol) of dicyclopentadiene was added to the mixture, followed by 0.33 mL (3.0 mmol) of a 31% aqueous solution of hydrogen peroxide. After thorough stirring, the mixture was allowed to stand at 25 °C. After 96 hours at 25 °C, extraction was performed with the solvent. The solvent was evaporated to give 0.166 g (99% yield, 99% selectivity) of the corresponding Dicyclopentadiene diepoxide.
Chemical Properties
white to yellow-beige crystals or
Uses
Dicyclopentadiene diepoxide acts as an intermediate for epoxy resins, plasticizers and protective coatings. It finds application as a rubber additive and adhesives, which is used at high temperature. Further, it is used in the preparation of endo-3-hydroxy-exo-9-oxa-exo-tetracyclo[5.3.1.02,6.08,10]undecane using lithium aluminum hydride as a reagent.
Safety Profile
Poison by ingestion andintravenous routes. Mildly toxic by skin contact. A skinirritant. When heated to decomposition it emits acridsmoke and irritating fumes.
