Síntesis de zeolitas

Abstract

En la presente invención se describe un procedimiento general que, mediante el empleo de tensioactivos, permite acortar los tiempos de síntesis de materiales microporosos cristalinos basados en sílice con canales cuya apertura de poro está formada por 10 ó 12 tetraedros de sílice. Este procedimiento se basa en la adición a la mezcla de reacción en la cual se forma la zeolita, de un tensioactivo que puede ser catiónico, amónico o neutro.

Además este nuevo método de síntesis aumenta el rendimiento de los reactivos empleados en la síntesis de zeolitas y la estabilidad de los materiales formados, permitiendo controlar el tamaño de cristal. Y en los casos en que existe competencia de crecimiento de distintos materiales microporosos, es posible mediante una adecuada selección del surfactante, favorecer la aparición de una fase respecto de la que compite con ella.
