【Abstract】 The effect of feed ratio and catalysts on the yield of styrene oxide has been investigated. The yield of 80.6%(content 97.5%) of styrene oxide was obtained under the optimum conditions. When the recovered NaBr solution was reused three times, for 1mol styrene the average yield of styrene oxide and NaBr consumption were 72.5%(content 92.7% of styrene oxide) and 0.46 mol, respectively.更多还原
