【摘要】 在苯乙烯100 mmol,n(钨酸钠)∶n(草酸)∶n(苯乙烯)∶n(30%H2O2)=2.0∶3.2∶100.0∶440.0,92℃的反应条件下,用GC-MS和GC-IR跟踪分析了反应物和反应产物。根据其含量随反应时间的变化关系,提出了苯乙烯氧化为苯甲酸可能经过两条途径的反应机理。更多还原

【Abstract】 Reactants and products were analyzed quantitatively in situ under the reaction conditions as follows: styrene was 100 mmol,n（sodium tungstate dihydrate） ∶n（oxalic acid） ∶n（styrene） ∶n（30% H₂O₂）=（2.0） ∶3.2 ∶100.0 ∶ 440.0,reaction temperature was 92 ℃.The possible mechanism of the oxidative reaction was proposed according to the relationships between their amount and the reaction time.更多还原
