英文摘要: The epoxidation of propylene catalyzed by a reaction-controlled phase transfer catalyst with H2O2 generated by the oxidation of 2-ethylanthrahydroquinone with molecular oxygen in the organic solvent was investigated. Effects of reaction temperature, reaction time, H2O2 concentration, catalyst concentration, and additives on the epoxidation were studied. Under the suitable conditions, the yield of propylene oxide, based on 2-ethylanthrahydroquinone, was above 85.6% in the fifth cycle. The results of P-31 MAS NMR of the recovered catalyst showed that the catalyst composition tended to being stable after the third cycle.
