Abstract
A synthetic crystalline zeolitic sodium aluminosilicate having a composition expressed as oxides of 0.9\sB0.2Na2O=Al2O3=5 to 6 SiO2=0 to 9 H2O and having a specified X-ray diffraction pattern is prepared by forming an aqueous sodium aluminosilicate mixture, the major source of silica being aqueous colloidal silica sol, having a composition expressed in terms of oxide-moleratios falling within one of the following ranges: <TABS:0972831/C1/1> (where III is a preferred example of I and IV and V are preferred examples of II), maintaining the reactant mixture at ambient (12 DEG to 38 DEG C.) temperature for at least 20 hours but not more than 40 hours for Range I and III and for at least 16 hours but not more than 40 hours for Ranges II, IV and V, heating the reaction mixture to 90 DEG to 105 DEG C. and maintaining the elevated temperature until the zeolite Y1 crystallizes, and separating the crystals. For composition Ranges I and III crystallization may be for 3 to 8 days, while ranges II, IV and V require 24 hours to 65 hours. Zeolite Y1 may be activated by heating to effect hydration water loss, e.g. as high as 450 DEG C. in air, vacuum, or other gas, preferably 350 DEG C. at 10-5 mm. Hg, when it will absorb at least 30 wt. per cent O2 at 100 mm. Hg and - 183 DEG C. In examples reaction mixtures are prepared from sodium aluminate, caustic soda and colloidal silica. Specifications 777,233 and 909,266 are referred to.
