  Preparation, Characterization and Reactivity of Keggin Type Phosphomolybdates, H3−2x Ni x PMo12O40 and (NH4)3−2x Ni x PMo12O40, for Adipic Acid Synthesis

  摘要：

  Two H3-2x Ni (x) PMo12O40 and (NH4)(3-2x) Ni (x) PMo12O40 Keggin type heteroploysalts series (x: 0.25-1.5) were synthesized and characterized by IR spectroscopy, XR diffraction and thermal analysis (TG). Their catalytic properties were studied in the oxidation reaction of cylohexanone and cyclohexanone/cyclohexanol mixture to adipic acid in presence of hydrogen peroxide and in absence of solvent. The effects of catalyst/substrate molar ratios and heteropolysalt composition on AA yields were examined. TG analysis allowed to confirm the x value. Obtained catalytic results showed that both salts series are efficient for oxidation of cylohexanone and cyclohexanone/cyclohexanol mixture. Adipic acid yield achieved 45 % in the cyclohexanone oxidation in presence of (NH4)(0.5)Ni1.25PMo12O40 with a catalyst/substrate molar ratio of 10(-3).

  Electronic Activity Relationship for Methacrolein Formation Over 4th Period Transition Metal Phosphomolybdates

  摘要：

  Phosphomolybdate compounds have been investigated for their structural characteristics and oxidation activity toward isobutane. The phosphomolybdates were synthesized from phosphomolybdic acid and the fourth period transition metal cations Cr3+, Mn2+, Fe3+, Fe2+, Co2+, Ni2+ Cu2+, Cu+ and Zn2+. Two compounds were synthesized per transition metal: where (i) all the protons had been replaced by the particular transition metal, and (ii) only partial proton replacement leaving a single proton per phosphomolybdate. X-ray diffraction analysis has shown that a primitive cubic phase is apparent with some of the transition metal phosphomolybdates. Each solid was exposed to isobutane using the anaerobic low-pressure steady-state technique. Category 1 exponential-like distributions of methacrolein were observed with all the transition metal phosphomolybdates, except the lower oxidation state iron and copper salts, Fe-1.5[PMo12O40] and Cu-3[PMo12O40] respectively. Activation energies ranged from 51.31 +/- A 0.27 kJ mol(-1) (Cr[PMo12O40]) to over 200 kJ mol(-1) (Zn-1.5[PMo12O40]). Phosphomolybdates with counter cations which are one or two electrons deficient from either a 3d (5) or 3d (10) configuration (in this case 3d (3), 3d (8) or 3d (9)) had the lowest activation barriers for methacrolein formation. A computational investigation into HOMO-LUMO band gap energies agrees with the association. The presence of protons also enhances Category 1 product formation and may be attributed to migration of H+ through the bulk of the solid.

  磷钼酸镍盐作为双功能均相可回收催化剂，用于醛无碱转化为酯

  摘要：

  合成了磷钼酸镍盐（NiHPMA），并通过各种物理化学技术（如 EDX、紫外-可见光谱、FT-IR、拉曼光谱和 XPS）进行了表征。FT-IR 和拉曼光谱证实了 Ni 作为抗衡阳离子的存在，而紫外-可见光和 XPS 研究证实了催化剂中Ni( II ) 的存在。评估了催化剂对苯甲醛串联转化为苯甲酸乙酯的双功能活性，发现极少量的Ni（2.64×10 -3 mmol）增强了对苯甲酸酯的选择性。通过紫外-可见光谱和拉曼光谱进行了详细的机理研究，以证实两种中间体物种，Mo-peroxo 和 Ni-oxo，对酯具有更高的选择性。此外，还进行了确定附加原子（杂多酸）的影响的研究。还发现该催化剂在优化条件下对于多种醛是可行的。
