Si(CO2H5)4 (TEOS)
Colorless liquid. Flammable. Slightly soluble in water, hydrolysis is slow in pure water, and can accelerate hydrolysis in the presence of acid or base; The reaction with boiling water gives silica sol without electrolyte. Ethyl orthosilicate reacts with higher alcohols or their esters in the presence of a catalyst.
