Abstract
The present invention is characterized in that it is a process for synthesizing an organic/inorganic composite that not only comprises an oxide of silicon and metal, oxide which includes a bond being expressed by 'M-O-M' (where 'M' independently represents silicon atom or metal atom), but also possesses an organic group which is bonded to a part of silicone atoms at least; and it includes: a preparation step of preparing a raw-material solution by dissolving an organo alkoxysilane, which possesses one or more alkoxy groups and has the silicon atom that is bonded with the organic group by covalent bond, and a metallic compound, which includes the metal atom, in a first solvent, which is a polar solvent; a reaction step of synthesizing the organic/inorganic composite by not only hydrolyzing the organo alkoxysilane and the metallic compound but also condensing them by means of dehydration; and a removal step of adding a second solvent, which does not dissolve compatibly with a solution that has undergone the reaction step, to the solution, thereby dissolving the organic/inorganic composite in the second solvent, and thereafter removing another solution, which does not dissolve compatibly with the second solvent. It is possible to recover the organic/inorganic composite readily by means of the present synthesizing process.
