Descripción

[EN] A new synthesis procedure for the synthesis of ITQ-7 zeolites is reported that has been afforded by combining theoretical and experimental approaches. This new synthesis method is specially relevant since the earlier procedure reported in the literature [1] is not any longer applicable because the principal precursor of the Structure directing agent (SDA) employed in that route is not commercially available. Here, we present a convenient method for synthesising ITQ-7 zeolites using a family of new SDAs that can be easily prepared from a-terpinene and maleimide as main reactants. The appropriate fitting of the new SDAs within in pores of ITQ-7 structure is highlighted by studying the synthesis in the presence of the non-substituted SDA which leads to closely related structure of polymorph C of the Beta zeolite (BEC code). Finally, the differences and similarities between the two synthetic routes described for preparing ITQ-7 zeolites are discussed in this work.
