PROCESS FOR FORMING ALUMINO-SILICATE DERIVATIVES

摘要

A process for the preparation of an amorphous alumino-silicate derivative which involves reacting a solid corresponding starting material with MOH where M is alkali metal or ammonium cation. The solid corresponding starting material may be selected from montmorillonite, kaolin, natural zeolite (e.g., clinoliptolite/heulandite) as well as illite, palygorskite and saponite and additional reactant MX wherein X is halide may be utilised in conjuction with MOH. The invention also includes alumino-silicate derivatives of the general formula MpAlqSi2Or(OH)sXt.uH2O as well as alumino-silicate derivatives of the general formula MpAlqSi2Or(OH)s.uH2O.
