| Abstract: | Influence of oil absorbing capacity and specific surface area on precipitated silica was studied in this article,which was obtained when using ethylene silane A-151 in the preparing silica from diatomite.The studies demonstrated that the size of modifying product is uniform and nano-meter,the largest specific surface area of all products is 232.908 m2/g,which was achieved when using w 4 weight parts of A-151 to modify the silica,chemical adsorption occurred between the surface of precipitated silica and modifying agent molecule. |
