A PROCESS FOR THE PREPARATION OF ALUMINOSILICATE ZEOLITE OF TYPE NA-P

Abstract This invention relates to a process for the preparation of aluminosilicate zeolite of type Na-P. The invention relates to the preparation of crystalline micro porous aluminosilicate molecular sieve of Zeolite P type structrure exhibiting its suitability for several adsorption, ion-exchange and detergency processes of academic and industrial importance. The crystalline, porous aluminsilicate of type P zeolite structure, prepared by the process of the present invention are constituted of oxides of silicon and aluminum having well ordered porous structure consisting of channels of precisely defined and uniform dimensions.
