| 摘 要： | 对Co2+-NaX催化苯乙烯氧气氧化进行实验研究,采用气相色谱-质谱联用确定其产物的组成。分别以不同产物为原料在该条件下进行催化氧化实验,确定了苯乙烯氧化平行-连串反应网络,即在该体系下苯乙烯氧化主要发生两类平行反应,一反应是苯乙烯环氧化为环氧苯乙烷;另一反应是苯乙烯氧化裂解生成苯甲醛和甲醛,苯甲醛能够部分氧化生成苯甲酸,而大部分甲醛则被深度氧化为CO2和H2O。并对苯乙烯氧气氧化反应机理进行探讨。

| Abstract: | The reaction process of styrene oxidation with oxygen over the Co2+-NaX catalyst was studied and the oxidation products were identified by the gas chromatography-mass spectrometry(GC-MS) method.The parallel-consecutive reaction network was determined using different oxidation products with oxidation being realized at the same reaction conditions.Two parallel reactions were carried out as follows:one was the epoxidation of styrene to styrene oxide,and the other was the oxidative cleavage of styrene into benz... |
