Full use of factors promoting catalytic performance of chitosan supported manganese porphyrin.

Abstract：

:In order to make full use of the impact of internal and external factors on the performance of title catalyst for ethyl benzene oxidation, the key internal influencing factors on the catalytic performance were modulated by coordinating and grafting manganese porphyrin to mesoporous and macroporous chitosan, and the important external factors (i.e. oxidation reaction conditions) were optimized using Response Surface Methodology. Under the Response Surface Methodology optimized oxidation reaction conditions (176.56 °C, 0.59 MPa, and 0.25 mg amount of manganese porphyrin), the catalyst could be used at least five times. The ethyl benzene conversion, catalyst turnover numbers, and yields reached up to 51.2%, 4.37 × 106 and 36.4% in average, respectively. Compared with the other optimized oxidation reaction conditions, the corresponding values increased 17%, 26% and 53%. Relative to the manganese porphyrin, the catalytic performance and efficiency of the immobilized catalyst had notably increased.

  • Molecular characterization of woodchuck IFI16 and AIM2 and their expression in woodchucks infected with woodchuck hepatitis virus (WHV).

    abstract：:IFI16 and AIM2 are important DNA sensors in antiviral immunity. To characterize these two molecules in a woodchuck model, which is widely used to study hepatitis B virus (HBV) infection, we cloned and analyzed the complete coding sequences (CDSs) of woodchuck IFI16 and AIM2, and found that AIM2 was highly conserved in...
