HOLLOW ORGANIC SILICA STRUCTURE AND METHOD FOR PRODUCING SAME

摘要

Provided are a hollow organic silica structure having higher dispersibility that allows easy control of particle size and a method for the production thereof. A method for producing a hollow organic silica structure characterized in being provided with a first step for mixing an organic silane compound represented by general formula (1): R2-Si(OR1)3 (1) or general formula (2): (R1O)3Si-R3-Si(R1O)3 (2) with a solution containing silica particles, a second step for hydrolyzing the organic silane compound, a third step for aggregating the organic silane compound hydrolyzed in the second step on the surface of the silica particles with the silica particles as nuclei, and a fourth step for dissolving the silica particles that are the nuclei using a basic compound.
