The aluminosilicate form of ITQ-58 has been directly synthesized in the synthesis gel SiO 2 -Al 2 O 3 -Na 2 O-H 2 O using Si/B-ITQ-58 zeolite as seed. Si/Al-ITQ-58 exhibits good crystallinity, high surface area, tetrahedral Al 3+ 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.
