ABSTRACT:
A prereaction mixture which is useful in the preparation of porous silica compositions with uniform pore sizes. The porous silica composition comprises a substituted nitrogen-containing siliconate, a colloidal silica and a soluble alkali silicate. By the addition of the substituted nitrogen containing siliconate to either the colloidal silica or soluble silicate, or by combining all three ingredients, a stable solution results, thereby avoiding the premature polymerization of the colloidal silica upon the addition of the soluble silicate. The soluble alkali silicate can have a metal cation which is selected from the group consisting of potassium and sodium.
