ABSTRACT:
Process for preparing particulate, porous, amorphous water-insoluble poly(alumino-silicate) having a Si/Al ratio of 2:1 to 100:1, of high surface area, and in high yield, by mixing an aqueous solution of an alkali metal aluminate and an aqueous solution of silicic acid, allowing the aluminate and silicic acid in the resultant reaction mixture to polymerize to poly(alumino-silicate), and thereafter removing sufficient water from the reaction mixture to permit recovery of the particulate poly(alumino-silicate) therefrom; and particulate poly(alumino-silicate) prepared thereby.
