| Inhoud: |
A study of the condensation of hydrolyzed tertaethylorthosilicate (TEOS) was conducted to investigate the influence of solvent polarity. A non-aqueous microemulsion was formed to which was added water (pH 1) and TEOS. The various condensation products were observed with 29Si NMR of systems of differing amounts of formamide and decanol/decane at increasing time intervals. The solvent polarity of the solvent system was found to clearly influence the initial and final rates of condensation, despite the fact that the specific condensed moieties were the same in each of the systems studied. |
