BASF (CHINA) COMPANY LIMITED
|Title:||HIGHLY EFFICIENT SOLIDOTHERMAL SYNTHESIS OF ZEOLITIC MATERIALS|
A process for preparing a zeolitic material having a zeolitic framework structure which exhibits a molar ratio (aAl2O3) : SiO2 or a crystalline precursor thereof, comprising (i) pre-paring a mixture comprising H2O, one or more compounds comprising Si from which SiO2 in the zeolitic framework structure is formed, said one or more compounds compris-ing a silica gel exhibiting a molar ratio (c H2O) : SiO2 and optionally one or more com-pounds comprising Al from which Al2O3 in the zeolitic framework structure is formed; (ii) subjecting the mixture obtained in (i) to crystallization at a crystallization temperature in the range of from 110 to 350 ℃, preferably in the range of from 190 to 350 ℃, and for a crystallization time in the range of from 0.1 to 48 h.
