Patent

CA 2007819

Dual zone porous materials having an external zone and an internal zone are prepared by contacting a suspension of a porous support, such as particulate silica, in a solvent with a halosilane and a catalyst for the halosilane in order to form silyl groups of a first type predominantly on the external surfaces of the porous support. Preferably, thereafter the porous support is contacted with a silane having silyl groups of a second type in order to form silyl groups of the second type predominantly on the internal surfaces.
