  后合成方法对NaY沸石二级介孔结构的数量和大小的影响及其对催化剂负载量的影响。在常规加热条件下合成黄嘌呤的高效，环保催化剂

  摘要：

  已经使用了几种鉴定技术来研究脱铝Y沸石的制备方法对催化剂负载量的影响。在本文中，NaY沸石通过乙二胺四乙酸（H 4EDTA）处理。在这种方法中，从沸石的超笼中除去了骨架外的铝，从而增加了Si / Al的比例和孔体积。因此，与（0.0875 g / g等于0.043 mmol / kg）相比，EDTA处理（MPA-MDAZY）中的沸石超笼中的钼磷酸（MPA）负载增加（0.1 g / g等于0.049 mmol / g载体）。 g支持物）以水热法（MPA-DAZY）。XRF，AAS，FTIR，SEM，BET，XRD和WDX分析也证实了这些结果。减少反应时间和增加EDTA处理对水热法的催化活性可能与基于去除多余骨架铝的高催化剂负载量有关。在黄嘌呤合成反应中已经比较了两种催化剂的催化活性。

• Mg(BF4)2 doped in [BMIm][BF4]: A homogeneous ionic liquid-catalyst for efficient synthesis of 1,8-dioxo-octahydroxanthenes, decahydroacridines and 14-aryl-14H-dibenzo[a,j]xanthenes

  A homogeneous ionic liquid made up of 0.5 mol% Mg(BF4)(2) doped in [BMIm]BF4 was obtained from a mixture of MgCl2 and [BMIm]Cl subjected to anion exchange with NaBF4. The ionic liquid efficiently catalyzes the synthesis of 1,8-dioxo-octahydroxanthenes, 14-aryl-14H-dibenzo[a,j]xanthenes, and 1,8-dioxo-decahydroacridines, giving excellent yields in short periods of time at 80 C. The integrity of the ionic liquid remains reasonably unchanged when it is separated from the reaction mixture by water extraction, as it can be recycled several times without any loss of activity in each of the title syntheses. Magnesium cation, though in low concentration, appeared as an essential element of this ionic liquid catalysis, perhaps due to its non-coordinated existence giving rise to a promoted Lewis acidic characteristic. Application of this new homogeneous catalyst system offered the advantages of high yields, short reaction times, and easy workup procedure compared to the conventional methods of the syntheses.
