| titleOfInvention | METHOD FOR PRODUCING A ZEOLITH A WITH VERY FINE CRYSTALLINE PARTICLES |
| abstract | Microcrystalline zeolite A prodn comprises the prepn of (a) an aq alkali aluminate soln kept at pH above 10.5, (b) an aq alkali silicate soln and (c) water having a specific pH, in quantities such that the metal oxide quantities in the starting materials of solns (a), (b) and (c) correspond to mol ratios SiO2:Al2O3 1.4-2.3 and M2O:Al2O3 1.2-4.5 (where M is alkali metal). Soln (c) pH is predetermined so that the alkalinity of the combined solns (a), (b) and (c) as calculated from the pH and quantities of solns (a), (b) and (c) is 1-4.5 N. Each soln (a) and (b) is stirred, at a constant rate, into soln (c) kept at 60-110 deg C. The addn of the total soln (a) and (b) quantities is completed within the same period. The deposited prod obtd is subsequently stirred at 60-110 deg C. Prods are used as zeolite builders for cleansing- and detergent compsns. |
