Claim 7
Dependent Claim
110 words
A process for preparing a composition comprising a crystalline, layered zirconium phosphate-type material having silica pillars intercalated between the layers of said material wherein said silica pillars comprise at least two silicon atom layers, which process comprises contacting a zirconium phosphate-type material with a solution of a polyhedral oligosilsesquioxane of the following general formula (ZSiO 1.5 ) n (OSiZ 2 ) m , wherein n and m are zero or integers and n + m does not equal zero and Z is an organic moiety containing an atom(s) possessing cationic and/or coordinating characteristics with the proviso that all of the Z's on a particular oligosilsesquioxane need not be the same.
Claim 8
Dependent Claim
110 words
A process for preparing a composition comprising a crystalline, layered zirconium phosphate-type material having silica pillars intercalated between the layers of said material wherein said silica pillars comprise at least two silicon atom layers, which process comprises contacting a zirconium phosphate-type material with a solution of a polyhedral oligosilsesquioxane of the following general formula (ZSiO 1.5 ) n (OSiZ 2 ) m , wherein n and m are zero or integers and n + m does not equal zero and Z is an organic moiety containing an atom(s) possessing cationic and/or coordinating characteristics with the proviso that all of the Z's on a particular oligosilsesquioxane need not be the same.
