  Mixed Oxides as Highly Selective Catalysts for the Flash Pyrolysis of Phenacyl Benzotriazole: One-Pot Synthesis of Dibenzazepin-7-one

  摘要：

  The one-pot synthesis of dibenzo[b,d]azepin-7-one (3) was selectively achieved from 1-phenacyl-1,2,3-benzotriazole (1) using the catalytic flash vacuum pyrolysis (cfvp) methodology. Catalysts with the scheelite structure ABO(4) (A = Ca2+, Sr2+, Ba2+ and B = Mo6+, W6+) and fergusonite BiVO4 were explored in this new catalytic reaction. These oxides promoted high conversion of starting material at lower temperatures than those observed for noncatalytic reactions. The chemical nature of A and B cations in the scheelite structure showed a strong influence on the formation toward the desired azepinone. In addition, the catalyst's morphology had a significant influence on the course of the cfvp reaction.

• Microstructure and Spectroscopic Properties of AMoO4 (A = Ca, Ba) Particles Synthesized via Cyclic Microwave-Assisted Metathetic Route
  作者：Chang Sung Lim

  DOI：10.14233/ajchem.2014.16519

  日期：——

  AMoO4 (A=Ca, Ba) particles have been successfully synthesized via cyclic microwave-assisted metathetic route in ethylene glycol followed by further heat-treatment. The AMoO4 (A=Ca, Ba) particles were well crystallized after heat-treatment at 400-600 °C for 3 h. The microstructures exhibited fine morphologies with sizes of 0.5-1 and 1.5-2 μm for the CaMoO4 and BaMoO4 particles, respectively. The synthesized AMoO4 (A=Ca, Ba) particles were characterized by X-ray diffraction, scanning electron microscopy. Other spectroscopic properties were also examined using photoluminescence emission measurements and Raman spectroscopy.

This paper presents a study, performed by X-ray diffraction, scanning electron microscopy, Raman and optical absorption spectroscopies of the stability as a function of the thermal treatment temperature TC of a simplified Mo-rich nuclear waste glass. The impact of the addition of a high amount of Nd2O3 on the thermal stability of this glass is studied. For comparison

  在为固定放射性废物而开发的硼硅酸盐玻璃中加入高含量的 MoO3 可能会导致富钼相的结晶，这可能会导致玻璃的长期性能下降。因此，必须了解它们的结晶机制以及废物（例如稀土）中存在的其他丰富裂变产物的可能影响，以便在玻璃制备过程中控制或避免它们的形成。本文介绍了一项研究，该研究通过 X 射线衍射、扫描电子显微镜、拉曼光谱和光学吸收光谱进行了稳定性与简化的富钼核废料玻璃的热处理温度 TC 的函数关系。研究了添加大量 Nd2O3 对这种玻璃的热稳定性的影响。为了比较，还介绍了不含 Mo 的富含 Nd2O3 玻璃的热稳定性。介绍了这些玻璃中形成的所有相（CaMoO4、Na2MoO4、Ca2Nd8(SiO4)6O2（磷灰石））的结晶范围以及它们的结构和微观结构随 TC 的演变。在富含 MoO3 的玻璃中引入 Nd2O3 会抑制钼酸盐的结晶（增加 Mo 溶解度），只要不形成磷灰石，这表明 [MoO4]2-

  A convenient and systematic solvothermal pathway towards alkali and alkaline-earth molybdates has been established. The solvothermal treatment of a molybdenum-based precursor material (yellow molybdic acid, MoO3⋅2 H2O) with ionic additives (alkali or alkaline-earth halides) provides access to a spectrum of molybdates. Their particle morphology can further be addressed by optimizing the reaction conditions
