Highly crystalline zeolites, synthesis from

The synthesis of pure and highly crystalline zeolites from alluminosilicate hydrogels requires the study of the simultaneous effects of different parameters involved in the synthesis. Most of these zeolites are prepared in presence of organic directing... 

Zeolites are microporous crystalline aluminosilicates built from corner-connected TO4 (T = Si or Al) tetrahedra. Their micropores with uniform dimensions give rise to molecular sieve properties. Tetracoordinated aluminum atoms lead to ion-exchange properties and make internal acid sites possible. They are economically important as detergent builders, as adsorbents, and, because zeolites have high thermal stability, as catalysts in the petrochemical industry. They are also considered to have a high potential as catalysts in the synthesis of fine chemicals.
