Efficient heterogeneous Cu-catalyzed aerobic oxidation of benzyl alcohols was discolsed. The combination of HKUST-1 and ABNO exhibited enhanced catalytic activity compare to the previous HKUST-1/TEMPO system in aerobic oxidation of benzyl alcohols. It was observed that the present catalyst was intrinsically heterogeneous and reusable. 相似文献

In order to remove U, Tc, and Np, which are positioning materials or target nuclides for transmutation, from the high-level radioactive waste, condition of co-extraction and sequential and sequential stripping of the nuclides wer studied by using 30 vol.% TBP. On the basis of the experiments ferformed on each element of U, Tc, and Np, a combination of co-extraction of U, Tc, Np Tc stripping Np stripping U stripping was suggested. To enhance the Np extraction yield, the electrolytic exidation of Np(V) was required at the co-extraction step. For the stripping of Tc 5M HNO3, of Np the electrolytic reduction of Np(VI) to Np(V), and of U 0.3M sodium carbonate were used. Phase ratios (O/A or A/O) were recommended to be of 2-3, for co-extraction and for stripping. 相似文献

The reactions of manganocene, Cp2Mn, with 2-aminopyridine (L1H) or 2-amino-3-bromo-5-methylpyridine (L2H) give the novel hexanuclear and octanuclear Mn(II) amido cage compounds [Cp2Mn3(L1)4]2 (1) and [Mn8(L2)12(mu 4-O)2] (2); magnetic measurements on which provide a rare insight into the magnetic properties of amido-bridged metal clusters. 相似文献
