Abstract:为了研究氧等离子体对丙烯的活化和氧化作用,在室温和大气压下,以分子氧为氧化剂,采用介质阻挡放电方法进行了直接气相氧化丙烯生成环氧丙烷、丙醛等C3氧化产物反应的研究.实验考察了丙烯/氧气比值、介质阻挡放电频率及介质阻挡放电电压对丙烯/氧气转化反应的影响.结果表明:用介质阻挡放电法可转化丙烯和氧气选择性氧化生成环氧丙烷、丙醛、丙烯醛和丙酮等C3氧化产物,适当调节各相关参数可提高C3氧化产物的总收率.在介质阻挡放电电压为17 2 kV、总反应气流速为160 8 mL/min、介质阻挡放电频率为1 38 kHz、φ(C3H6)/φ(O2)=1:200的条件下,得到了丙烯转化率、C3类氧化产物的总选择性及总收率分别为3.9%,63.6%和2.5%的结论.
