作者： Lin Fei xiao Jia Jian peng Chun Gu xia State Key Laboratory for Oxo Synthesis and Selective Oxidation Lanzhou Institute of Chemical Physics Chinese Academy of Sciences and Graduate School of Chinese Academy of Science Lanzhou 730000

Silica sulfuric acid in which sulfuric acid is immobilized on the surface of silica gel via covalent bond has been proved to be green catalyst for liquid-phase Beckmann rearrangement of oximes in dried dioxane at room temperature. Excellent conversion and selectivity were acquired in the Beckmann rearrangement of cyclohexanone oxime. The catalyst system was recycled and reused.

Influence of α-Al_2O_3 and AlF_3 on pyrohydrolysis of Li_3AlF_6

引用

Nuclear Science and Techniques 2018年第9期29卷 148-156页

作者： Jia peng xiao-Bei Zheng Yu-xia Liu Lan Zhang Shanghai Institute of Applied Physics Chinese Academy of SciencesShanghai 201800China University of Chinese Academy of Sciences Beijing 100049China CAS Innovative Academy in TMSR Energy System Shanghai 201800China

In this study, Li_3AlF_6 was employed to simulate the molten salt LiF–BeF_2 to explore its pyrohydrolysis behavior and that of its components, i.e., LiF and AlF_3,respectively. The influence of the accelerators α-Al_2O_3 and AlF_3 on the pyrohydrolysis of LiF and Li_3AlF_6 was investigated. Finally, the solid pyrohydrolytic products were characterized by means of X-ray diffraction, and the corresponding reaction mechanisms were proposed. These experimental results indicated that AlF_3 was completely hydrolyzed to the corresponding oxide α-Al_2O_3 at 650 ℃ in 1 h, whereas the complete hydrolysis of LiF and Li_3AlF_6 required the assistance of either α-Al_2O_3 or AlF_3 under the same conditions. The influence of the accelerator α-Al_2O_3 and AlF_3 on the pyrohydrolytic behavior of Li_3AlF_6 provides references for future research studies on the pyrohydrolysis of LiF–BeF_2 and multi-component molten salts.
