The aluminosilicate form of ITQ-58 has been directly synthesized in the synthesis gel SiO2-Al2O3-Na2O-H2O using Si/B-ITQ-58 zeolite as seed. Si/Al-ITQ-58 exhibits good crystallinity, high surface area, tetrahedral Al3+ species, and middle acid sites. The acidic form of Si/Al-ITQ-58 zeolite, is an excellent alternative heterogeneous catalyst with high yield and simple product separation, used for Biginelli reaction. Therefore, with the second case, we further confirm the new function of seed-assisted synthesis, i.e., direct aluminosilicate preparation.

种子辅助直接合成硅铝酸盐形式的 ITQ-58 沸石
ITQ-58 的铝硅酸盐形式已在合成凝胶 SiO 2 -Al 2 O 3 -Na 2 O-H 2 O 中使用 Si/B-ITQ-58 沸石作为种子直接合成。Si/Al-ITQ-58 具有良好的结晶度、高表面积、四面体 Al 3+物种和中等酸性位点。Si/Al-ITQ-58 沸石的酸性形式是一种出色的替代非均相催化剂，收率高，产物分离简单，用于 Biginelli 反应。因此，在第二种情况下，我们进一步证实了种子辅助合成的新功能，即直接制备铝硅酸盐。
