The Oxidation Reaction Of Alkane Catalyzed By Phthalocyanine With Molecular Oxygen As Oxidant

The oxidation of saturated C-H bond is an important technical method to obtain oxygenous organic compounds. With the development of petroleum chemical industry, many oxidation technologies have been applied triumphantly. This thesis presents the study on the oxidation of saturated alkane catalyzed by metallophthalocyanine with molecular oxygen as oxidant in the simulated under water-free condition.First. we synthesized series of metallophthalocyanine with different central ions and different substituents, such as FePc(NO2)4. CoPc(NO2)4. MnPc(NO2)4. Pc(NO2)4. and FePc(NH2)(NO2)3, FePc(NH2)4, FePc. etc. Otherwise, we synthesized two kinds of ionic liquid—[bpy]Br and TBAB. The structures of them were affirmed by IR, UV-VIS spectrum and elemental analysis.Second, we studied the oxidation of heptane using metallophthalocyanine as catalysts with molecular oxygen as oxidant in the absence of solvent. Through investigating effects of reaction temperature, reaction time, oxygen pressure and the structure of catalyst on conversion of heptane, we got the optimal reaction conditions. Meanwhile, we also investigated the reuseability of catalysts.Finally. oxidation of alkane catalyzed by metallophthalocyanine with the molecular oxygen was investigated in ionic liquid for the first time. Some factors such as reaction tempareture, reaction time, oxygen pressure and amount of catalyst were conducted on conversion of alkane, and we got the optimal reaction conditions. In the presence of ionic liquid, the activity and stability of catalyst can increase remarkably.
