| Abstract: It was studied the hydrothermal synthesis of molecular sieve VPI-7 in Na2O-ZnO-SiO2-H2O system and mainly studied the influence of temperature, Na2O/SiO2, SiO2/ZnO on the synthesis. At the same time, the product was characterized by XRD, SEM and FT-IR. The results showed that:(1) pure VPI-7 can be synthesized when the ratio of SiO2/ZnO was in the range of 3.5～10, and with the increase of SiO2/ZnO, the crystallinity of the product increased;(2) SiO2/ZnO of the synthesized product was not in relation with that of the reactant linearly, which confirmed that the atom of Zn was orderly located in VPI-7. Referring the explaination of IR spectrum of alumi-nosilicate zeolite ,the adscription of FT-IR data has been done briefly. |
