The products of reaction between lead acetate and tetraethoxysilane (TEOS) in 2-methoxyethanol (CH3OC2H4OH) at 100°C were identified by kinematic viscosity measurement and IR and 1H-NMR spectroscopic techniques. Two reaction methods were used: Lead acetate and TEOS were directly reacted in Method I, whereas they were reacted with 2-methoxyethanol prior to the reaction in Method II. The reaction product in Method I is identified as (CH3COO)-Pb-O-Si-(OC2H4OCH3)3, which polymerized during prolonged heating. In Method II, lead acetate and TEOS changed to (CH3COO)-Pb-(OC2H4OCH3) and Si(OC2H4OCH3)4, respectively, by the reaction with 2-methoxyethanol. The reaction product in Method II was identified as (CH3OC2H4O)-Pb-O-Si-(OC2H4OCH3)3. No polymerization reaction occurred, because there was no acetyl group in the reaction product.
