Abstract

1,223,592. Zeolites. W. R. GRACE & CO. 22 March, 1968 [22 March, 1967], No. 14061/68. Heading C1A. Zeolite aluminosilicates having a silica: alumina ratio of 2:1 to 3:1 and having particles of predetermined size of 0.01 to 100 microns are prepared by dispersing a sodium aluminate solution having a Na 2 O; Al 2 O 3 ratio of 0À9:1 to 1À1:1 in a solution of sodium silicate having a Na 2 O: SiO 2 ratio of 0.75:1 to 1.0:1 in proportions to form a mixture having a silica: alumina ratio of 10:1 to 20:1, the sodium silicate solution being agitated at a constant rate while the sodium aluminate solution is added, and the mixture being maintained at 0‹ to 100‹ C. The mixing conditions are selected so as to produce particles of the required size, the mixing temperature being 0‹ C. for small particles and 100‹ C. for large particles and the mixtures being agitated vigorously for small particles and mildly for large particles. After mixing the solutions, zeolite particles are hydrothermally crystallized and separated from the solution. In the production of small particles, after the mixture has been formed at 0‹ C., it may be aged by stirring for 2 to 24 hours and heated to 80‹ to 100‹ C. to crystallize the product.
