N2 - The effect of the addition of tetramethylammonium ions on the distribution of silicate species in the methanolic solutions was studied by the trimethylsilylation technique. Tetramethylammonium ions affected silicate species formed in the hydrolysis of tetraethoxysilane, causing the singular formation of the cubic octameric silicate species in the methanolic solution. The recovery was higher in the methanolic solution than in the aqueous system. It was found that the presence of water was necessary for the singular formation, suggesting an interaction among silicate species, tetramethylammonium ions and water. It was also found that the formation of the cubic octamer started immediately after preparation of the solution.
