Patent ID: 7560094

Claim:
A process for producing a modified layered metallosilicate material, comprising the following first to fifth steps: First Step: a step of heating a mixture containing a template compound, a boron compound, a silicon-containing compound and water to thereby obtain a precursor (A); Second Step: a step of acid-treating the precursor (A) obtained in the first step, to thereby obtain a precursor (B); Third Step: a step of heating the precursor (B) obtained in the second step in the presence of a swelling agent so as to swell the precursor (B) to thereby obtain a precursor (C); Fourth Step: a step of modifying the manner of the stacking between layers in the precursor (C) obtained in the third step, to thereby obtain a precursor (D); and Fifth Step: a step of calcining the precursor (D) obtained in the fourth step, to thereby obtain a modified layered metallosilicate material.
