Title: Synthesis of epoxyethylbenzene with no-solvent method
Abstract: Epoxyethylbenzene is synthesized by styrene and using H2O2 as antioxidant,quaternary ammonium heteropolyphosphatotungstate as catalyst on no-solvent condition.The effects of reaction time,reaction temperature,ratio of styrene and H2O2,catalyst dosage and ac dosage on the reaction are investigated by single factor experiments and orthogonal experiments.Under the optimal reaction conditions:reaction time 6.5 h,reaction tempreature 55℃,n(C8H8)∶n(H2O2)=1.5∶1.0,16 g of quaternary ammonium heteropolyphosphatotungstate,2.5 g of ac and 100 mL of styrene,conversion of styrene is 78%,selectivity of epoxyethylbenzene is 89%.
