摘要：

The structures and the distribution of species formed by adding methyltriethoxysilane or 1,3-dimethyltetramethoxydisiloxane to a tetramethylammonium silicate methanolic solution, where the cubic octameric silicate species is predominantly present, have been studied. Me(n)Si8O20-n(8-n)- (n = 1-3) species have been formed in the solutions, which have the double eight-membered (Si4O4) ring siloxane skeleton structure consisting of both Si(O-)4 and MeSi(O-)3 units. indicating that Si(O-)4 units in the cubic octameric silicate anion can be displaced by MeSi(O-)3 units.
