| Abstract: | Influence of oil absorbing capacity and specifi c surface area on precipitated silica was studied in this article,which was obtained when using aminosilane KH-550 in the preparing precipitated silica from diatomite. The studies demonstrated that the size of modifying product is uniform and nano-meter,the largest specif ic surface area of all products is 250.184m2/g, which was achieved when using w4 weight parts of KH-550 to modify the silica, chemical adsorption occurred between the surface of precipitated silica and modifying agent molecule. |
