3. Propylene epoxidation in nonprotic solvent catalyzed by TS1 was studied.

4. The epoxidation of styrene - isoprene block copolymer ( SIS ) in different organic solvents was studied.

5. Sucrose epoxy resin 2-2 was prepared by epoxidation using peroxyacetic acid.

6. By one-step epoxidation of double bond in the side chain of cardanol, epoxy-cardanol has been synthesized, which may interact with diethylene triamine to form amino-cardanol.

7. Citral underwent selective epoxidation of sodium hyp rite and Wharton transposition to afford Linalool.

8. Besides these, the present calculations indicate that the epoxidation of ethylene is slightly endothermic or exothermic in sextet and quartet states, respectively.

9. In the epoxidation, chloroform and t butanol gave the best results.

10. The invention also provides a process for the epoxidation of an olefin and a process for the preparation of a chemical derivable from an olefin oxide.

11. Styrene epoxidation was carried out using styrene as the row material, molecular oxygen as the oxidant, and modified vanadium phosphorus oxide as the catalyst.

12. Recent progress on asymmetric epoxidation of alkenes by chiral catalysts was summaries.

13. The epoxidation of propylene to propylene oxide, using cumene hydroperoxide as oxidant, molybdenum glycol complex as catalyst and ethanol as solvent, has been investigated.
