Study on the oxidative degradation of macromolecular constituents of asphaltic sands with Mo(VI)complex as catalyst
钼（VI）配合物催化氧化降解沥青砂中重组分过程研究

This paper illustrates the reaction pattern of the catalytic oxidative degradation of macromolecule in asphaltic sands. Parameters, including reaction time, catalyst system, that affect the change in the weight of organic phase and residual phase, were investigated in detail. It was found that (MoO_2)(C_5H_7O_2)_2] is an effective catalyst for the oxidative degradation of macromolecule in asphaltic sands. The reaction of the catalyzed degradation is related to the oxidant, H~+ proton donator. In (MoO_2)(C_5H_7O_2)_2]/t-BuOOH/H_3PO_4 system, the conversion of asphaltene reaches 10.7% in organic phase and 20% in residual phase. The TLC-FID (Thin Layer Chromatography-Flame Ionization Detector) analysis indicates that the asphaltenes in asphaltic sands was transformed into resin and saturates. The yield of the degradation product is 11.7%.
