PURPOSE:To prevent the integration of spherical glass and the generation of odd-shaped particles in a method for dispersing an HF-contg. aq. solvent soln. of metalalkoxide into the organic medium which is insoluble therein and is the easily volatilizable liquid capable of dispersion by containing the specified substance in the above-mentioned organic medium. CONSTITUTION:An aq. solvent soln. contg. a small quantity of HF of metalalkoxide is added into the liquid organic medium to be dispersed and the hydrolysis of metalalkoxide is performed in the dispersed state to form the spherical glassy gel body. If necessary, the gel body is subjected to the high-temp. heat- treatment to obtain the spherical glass body. As the above-mentioned organic medium, the following easily volatilizable organic medium is used which is insoluble in the above-mentioned HF-contg. soln. and capable of dispersion and contains the long chain saturated fatty acid or a nonionic surface active agent together with it. By this method, the spherical glass body useful as the column packing material for chromatography and a carrier for enzyme immobilization or the like is obtained. |
