Title:
METHOD FOR PREPARING SILICA POROUS CRYSTAL
Document Type and Number:
WIPO Patent Application WO/2006/030741
Kind Code:
A1
Abstract:
A method for preparing a silica porous crystal, characterized in that it is a method for synthesizing a silica porous crystal through a hydrothermal reaction, which comprises forming a region having a high concentration of silicon in a part of a hydrothermal reaction vessel, and carrying out the hydrothermal reaction while allowing a bulk article comprising a compound containing silicon and oxygen and having been subjected to a surface-smoothing treatment, as a supply source of a part or all of the elements constituting the skeleton of the silica porous crystal, to be so present as for at least a part thereof to be within the above region having a high concentration of silicon. The above method allows the synthesis of a silica porous crystal having a size of 0.5 mm or more with good reproducibility and good efficiency.
