| titleOfInvention | Hydrophobic organosilicate modified silica gel |
| abstract | (57) [Summary] The present invention is a hydrophobic organosilicate-modified silica gel and a method for producing the same. The process of the present invention comprises two steps, in which the organosilicate modified silica hydrosol is heat treated at a pH of less than 1 in the presence of a strong mineral acid to form an organosilicate modified silica hydrogel. In a second step, the organosilicate-modified silica hydrogel was contacted with an organosilicon compound in the presence of a catalytic amount of a strong acid to achieve the hydrophobization of said organosilicate-modified silica hydrogel and thereby measured dry. to form a hydrophobic organosilicate-modified silica hydrogel having a surface area in the range of 100m 2 / g~750m 2 / g when. In a preferred method, the hydrophobic organosilicate-modified silica hydrogel is contacted with a sufficient amount of a water-immiscible organic solvent to convert the hydrophobic organosilicate-modified silica hydrogel into a hydrophobic organosilicate-modified silica organogel. . |
