Abstract

1300946 Active silica and silicates; zeolites PETER SPENCE & SONS Ltd 26 May 1970 [29 May 1969] 27132/69 Addition to 1193254 Heading C1A "Active" silica and silicates having the general formula. nNa 2 O : SiO 2 : xH 2 O, where n = 0 to less than 0À5, and x = at least 0À1, are produced in a process in which an "active" sodium silicate hydrate having an activity rating of at least 5 units is treated in an aqueous medium with the salt of a base, other than a metallic base, having a pKb in the range 2À0-9À0, or with a weak acid having pK a in the range 5À0-9À0 to remove or partially remove the cation from the sodium silicate. The sodium silicate hydrate treated is of general formula mNa 2 O : SiO 2 : yH 2 O, when m = 0À5-1À5 and y is greater than 0À05. Specified suitable bases are mono-, di-, and tri-methylamine and ethylamine, pyridine, piperidine and quinoline, hydroxylamine, and ammonium hydroxide. Suitable salts are chlorides, sulphates, nitrates, or carbonates, viz. amine hydrochlorides, the preferred salts being ammonium salts. Carbonic acid is specified as a weak acid of appropriate pK a value. The reaction to remove the cation may be carried out at a temp. in the range 10-30‹ C. In such a reaction the silica or silicate product is separated from the aqueous medium by filtration, is washed and dried. The "active" silica or silicate may be utilized in the preparation of synthetic zeolites having molecular sieve and base exchange properties by cystallization of said zeolite from a reaction mixture containing the required quantities of SiO 2 component, Al 2 O 3 component, cation component and water at a temperature in the range 30-120‹ C. with stirring when at least part of the SiO 2 component is "active" as prepared by the above method. Specified cations are Na<SP>+</SP> together with Li<SP>+</SP>, K<SP>+</SP>, Rb<SP>+</SP>, Cs<SP>+</SP>, Mg<SP>++</SP>, Sr<SP>++</SP>, Ba<SP>+</SP> <SP>+</SP> and NH 4 <SP>+</SP>: the zeolite: where d = 0-1, e = 6-8 and # is up to 10 and having a specified X-ray pattern, is exemplified.
