| Abstract: | Tungsten-containing mesoporous molecular sieves W-SBA-15 were synthesized under conventional hydrothermal conditions.The molecular sieves were characterized by means of X-ray diffraction and BET test.The catalytic performance of the molecular sieves W-SBA-15 for the oxidation of ethylbenzene to acetophenone was evaluated by using 30% H2O2 as oxidant and acetone as solvent.The optimized reaction conditions were determined to be reaction temperature of 120 ℃,reaction time of 8 h,catalyst mass fraction of 10.0%,and n（ethylbenzene）∶n（hydrogen peroxide）∶n（acetone） of 1∶2∶6.Under the optimized reaction condition,ethylbenzene was converted into acetophenone at a rate of up to 13.0%,and the selectivity of acetophenone was up to 88.3%. |
