摘　　要：采用微波法合成了双核酞菁钴,并采用红外光谱、紫外可见光谱、热重分析对其进行表征。以二苯并噻吩(DBT)为反应底物,考察双核酞菁钴对DBT催化氧化性能,筛选出较优催化剂,并进行脱硫反应工艺条件优化。结果表明,双核酞菁钴具有较好的催化性能,在室温下、双核酞菁钴用量为0.01 g(cat)/5 m L、空气流量为80 m L/min、反应温度为40℃、反应1 h,DBT脱硫率达到97.17%。催化剂重复使用5次,催化效果无明显下降。氧化产物经红外光谱、质谱分析为DBTO2。对芳香烃及烯烃进行了催化氧化实验,发现该工艺对油品的质量基本无影响。Binuclear cobalt phthalocyanine was synthesized by microwave method and characterized by infrared spectroscopy, UV-visible spectroscopy and thermogravimetry; its ca talytic performance in the oxidative desulfurizta ion of dibenzothiopeh ne （ DBT ） was investigated.The reus lts hs owed that the binuclear cobalt phthalocyanine exhibits the highest activti y among five catalyst ; over it, with the catalyst amount of 0.01 g（cat）/5 mL and air flow rate of 80 mL/min, the us lfur removal rate reaches 97.17% after reaction at 40℃for 1 h.The product of DBT oxidation is DBTO2 , as verified by the FT-IR and mass spectrometry.The catalytic performance in the oxidation fo aromat ics and ol efins was also investigated, which illustrates that current process using binuclear cobalt phthalocyanine as the catalyst has little influence on the quality of the oil product. Moreover, the catalyst can be reused for 5 times without significant decrease of its oxidation activity.
