Abstract
A process for preparing a crystalline synthetic aluminosilicate having the composition, expressed in terms of oxide molar ratios, (see formula) where M is a cation chosen from the group consisting of hydrogen, ammonia, an alkali metal and an alkaline earth metal, n is the valence of the cation X has a value between 4.3 and 5.55, Y has a value up to about 8, the crystals of said aluminosilicate being isotropic and having the X-ray diffraction spectrum of the derivatives of the alkali metal and the alkaline earth metal designated numerical values for the derivatives of sodium, potassium and calcium in Table A of the Attached memory, whose procedure comprises mixing a silica sol dispersed in water initially layers to form silica gel, an aluminum compound capable of forming alumina gel, water, and a water soluble alkali metal base, supplying the proportions of said ingredients an aqueous mixture, the composition of which, expressed in terms of oxide molar ratios, falls within the following ranges: M2C/SiO2: from 0.15 to 0.6 H2O/M2O: from 30 to 200 SiO2/Al2O3: from 2 to 10 where M is an alkali metal, keep the aqueous mixture at a temperature comprised in the range of around 25º to around 150ºC for a period between around 5 and around 200 hours, during which crystals of said aluminosilicate of alkali metal, and separate these crystals from the mother liquor.
