Abstract:
     The present invention discloses a crystalline molecular sieve contg. ZnO2, AlO2, SiO2 and PO2 tetrahedron group with 3-dimensional microporous frame structure. The emprical formula of these molecular sieves in anhydrous state is: mR: (Znw Alx Py Si2) O2, where R represents organic template existing in microporous system within crystalline, m represents moles of R per mole of (Znw Alx Py Si2)O2, w, x, y, and z are mole fractions of Zn, Al, P, and Si in oxide form of tetrahedron. The present invention also discloses the use of these molecular sieves as absorbent, catalyst, etc.
