Abstract
A synthetic crystalline zeolite, the same as that designated zeolite X in Specification 777,233, is prepared by ageing a calcined kaolinitic clay in an aqueous solution of sodium hydroxide and hydrous silica and thereafter heating the solution at 50 DEG C. to the boiling point to produce the zeolite, the weight ratio of the reactant, at least during the heating step being 9-20 parts H2O, 0,2-0,4 parts SiO2 and 0,9-2 parts Na2O per part of calcined clay. Calcination may be effected at 500 DEG -800 DEG C. for 1-18 hours and the ageing may be effected at 20 DEG -40 DEG C. The term "hydrous silica" includes in this context sodium silicate, and this is the preferred reactant. According to Example (1) kaolin calcined at 700 DEG C. for 2 hours was aged as a slurry in of sodium hydroxide and silicate at 25 DEG C. for 72 hours after which it was refluxed at 100 DEG C. for 10 hours and the zeolite recovered by filtering and washing. Further Examples 2, 4, 5 and 6 exemplify the effect of calcination timer and temperatures, whilst Example 7 exemplifies the use of calcined halloysite. Example 3 is comparative, the aging step being omitted and the product being sodalite. Ion exchanged forms of the zeolite X may be obtained by conventional means.
