Brief description of a zeolite by the continuous supply of an aqueous solution of sodium silicate and of an aqueous solution of sodium aluminate, the product obtained and the application of the product is in the detergency
Zeolites well suited for detergency, e.g., zeolites of type A, are adopted for mass production by simultaneously continuously introducing both an aqueous solution of sodium silicate and an aqueous solution of sodium aluminate into an unagitated first reaction zone to effect the continuous intimate admixture thereof, continuously transferring intimate admixture from said first reaction zone to a second zone of gelation to effect the continuous homogeneous gelling thereof, the time of retention of said intimate admixture in said first reaction zone being less than that period of time required for the gelation thereof, and thence effecting crystallization of a zeolite from said homogeneous gel.
