SYNTHETIC CRYSTALLINE ALUMINOSILICATE COMPOSITION AND METHOD FOR THE PRODUCTION THEREOF |
摘要 |
A synthetic crystalline aluminosilicate composition has the following chemical composition (in terms of molar ratios of oxides); 0.5-3M2/nO:Al2O3:15-30SiO2:0-50H2O wherein M represents a metallic cation and n is the valence of the metallic cation and also having an X-ray powder diffraction pattern having d-spacing as shown in the following Table. <TABLE> The novel composition is made by maintaining an aqueous solution containing dissolved SiO2; Al2O3; Na2O and the metal M in specified ranges of molar ratios at 150 to 200 DEG C under autogeneous pressure for 10 to 40 hours. By the practice of this invention, crystalline aluminosilicate of the modernite type possessing a high silica content is produced which is of high commercial value, for example, as a catalyst or molecular sieve. |
