    Abstract

    Lamellar organoammonium silicates with variable silicon environments have been synthesized by the reaction of a layered polysilicate kanemite with aqueous solutions of hexadecyltrimethylammonium (C16TMA) chloride. While the structure of kanemite is composed of only Q3 silicate species ((SiO)3SiO), SiO4 units with both Q3 and Q4 ((SiO)4Si) environments were present in the silicate frameworks of the lamellar C16TMA silicates. The Q4 species mainly formed by intralayer condensation of the Q3 species in the individual silicate sheets in kanemite rather than by interlayer condensation between the adjacent sheets. The intralayer condensation can be suppressed by lowering the reaction temperature and/or shortening the reaction time, which results in the relative retention of the silicate framework of kanemite in the lamellar C16TMA silicates.
