Abstract
A process for preparing crystalline alumino-silicate compositions has been developed. The process involves preparing a charge density mismatch reaction mixture comprising sources of aluminum, silicon, optionally an E metal and at least one charge density mismatch (CDM) template. The CDM template is an organic nitrogen containing template, in the hydroxide form, e.g. tetraethylammonium hydroxide and is characterized in that it is incapable of inducing crystallization. To this mixture there is added a solution comprising a second templating agent termed a crystallization template (CT). The CT can be an organic template different from the CDM template, an alkali metal, an alkaline earth metal and mixtures thereof.
