为研究空气等离子体对丙烯的活化作用,在室温和常压下,采用介质阻挡放电法,考察玻璃反应器材质种类及长度对丙烯转化率、环氧丙烷选择性及其他产物分布的影响.实验结果表明:介质阻挡放电法可转化丙烯和空气直接生成环氧丙烷;玻璃反应器材质种类对丙烯环氧化反应有显著影响;在其他条件不变的情况下,随着反应器长度增加,丙烯转化率迅速增加,环氧丙烷、丙醛和丙烯醛等C3类氧化产物的摩尔分数均降低.
In order to study the activation of propylene by air plasma, the effect of species and length of glass reactor on propylene conversion, propylene oxide selectivity and other product distribution was investigated by dielectric barrier discharge method at room temperature and atmospheric pressure. The results showed that the dielectric barrier discharge method can directly convert propylene and air to form propylene oxide. The material type of glass reactor has a significant effect on the epoxidation of propylene. Under other conditions, with the increase of reactor length, The conversion rate increased rapidly, and the mole fraction of C3 oxidation products such as propylene oxide, propionaldehyde and acrolein decreased.
