摘要：A cake or an aqueous suspension containing water and a zeolite which are practically inseparable from each other by filtration is neutralised with an inorganic or organic acid or a corresponding acid anhydride or salt so that the pH of the suspension after completion of addition is in the range from 9.5 to 12 and the pH of the suspension at rest after addition is in the range from 11.3 to 12.7. An organic polymer dispersant, which is soluble in water or dispersible in water at a concentration of at least 0.1 % by weight with respect to the anhydrous zeolite, is added to the neutralised zeolite suspension and the suspension obtained is stirred with a strong shearing action.
